The Feather That Cuts the Wind
She first met Kenichi after throwing over her shoulder when he touched her from behind. Due to them being late, they had to stand out of class. Miu offered to be his friend since she doesn't have any friends. She became very happy that he wanted to be friends with her, making Kenichi her very first friend. When Kenichi saw some thugs try to harass her, he jumped in to protect her only to land one weak punch. However, Miu defeated the thugs with little effort and decided to take Kenichi to Ryōzanpaku so he can learn martial arts and protect the people closest to him.
During his time there, Miu would be the one who worries over his condition more than others due to the masters' crazy training methods, occationally becoming horrified when he's left half-dead at the end of training or from his near death experience from Apachai. When Kenichi was forced to fight Takeda, Miu and Kenichi would have lunch together in hiding till Kenichi was strong enough to defeat him. After Miu saw Kenichi on the side of the roof of the school about to fall off with Takeda, Miu rushed over to save them and when she saw Kenichi unconscious and Takeda and Ukita over him, she became enraged believing they beat him up and brutally pounded the two of them (though Miu didn't really apologize afterwards due to the trouble they caused Kenichi in school). In order to protect Kenichi from Valkyrie of the Eight Fists (due to the former not wanting to fight the latter), Miu fought in his place and easily defeated her. When Miu got a part in a play and was supposed to kiss someone in it, Kisara wanted to ruin the play, Kenichi stopped her and kept the play on. However, Miu didn't kiss him and thanked Kenichi for what he did for her. She would occasionally help Kenichi when Ragnarok would want to fight him and watch his fights or keep others from interfering.
When Renka Ma, Ma Kensei's daughter showed up to take Kenichi back to her country Miu becomes extremely jealous but Kenichi declines making Miu relieved. The both would continue to fight over Kenichi's attention, revealing Miu developing feelings for Kenichi. Miu eventually becomes friends with Renka (due to her cat like appearance and her love for cats). When they all go to the pool, some thugs try to embarrase Miu and Kenichi would step in and defeat them. However, the thugs were actually just workers at Renka's uncles shop and just wanted to take her home and Renka eventually went for her uncle's sake.
When Miu and Kenichi were walking home one day, they saw Kisara tending to a cat and Miu stayed with her in the rain while Kenichi went to go and get an umbrella. Miu eventually becomes close friends with her cause of their love for cats. However, no one would take the cat and the two would be attacked by the Valkyrie's and Kisara tried to protect the cat and even when Kenichi arrived to help, due to his "no-hit women" policy, they were in trouble. Luckily, Shigure showed up and easily defeated them with a wooden spoon and they ran away embarrassed due to their clothes having been torn. When the cat was adopted by a family and Kenichi was too late to tell her that he could keep it at their dojo, he decided to do all of her chores to apologize for it.
When Miu takes Kenichi to the spot where they first met (when they were little and Kenichi doesn't remember at first), they meet Ryuto, Kenichi's old childhood friend and leader of Ragnarock. She watches Kenichi fight and when he loses, Ryuto takes his Yin Yang badge and bends it and takes Kenichi's due to his belief it always belonged to him.
When Kenichi is taken by her grandfather to train in the mountains, Miu would hang out with Kisara stating that she misses him. Kisara would tease Miu about her being a couple with Kenichi, causing her to get very flustered and trying to say that there just close friends. They both would fight the Valkyries and Kisara would fight Freya. After winning, Miu would watch Kenichi fight Ryuto with the masters having made a picnic. When Kenichi would use all the moves the masters use, she would be very surprised and amazed how well he's fighting. As he wins and is saved by the Elder, she first is very scarred that he may have been seriously hurt, but seeing him alright, she congradulates him and states she's glad he's alright.
After the defeat of Ragnarock, Kenichi is informed by Miu that though he's become stronger, he must not become arogant or he'll end up getting hurt in a fight if he underestimates his enimies. She tried to fight him to prove a point, but were interrupted by her classmates and left. They both went on a trip with Sakaki to introduce Kenichi to the real world of marital arts and Christopher Éclair would kidnap Kenichi and Sakaki and Miu would save him. After Sakaki defeated Christopher and Miu and Kenichi defeated the lower enemies, they went home.
With Li Raichi attacking the Shinpaku Alliance, Miu, Renka and Kenichi would go and help and after Kenichi defeated her, her father arrived and devistated all of them, including Miu who was no match. They were saved by the other masters. When his masters tell him to quit Ryōzanpaku, Kenichi refuses due to him shouting he can't let nice people like Li Raichi to go down the path of evil and wants to change that. The masters all state how proud they are of their disciple and state how wonderful it is to have Kenichi for him to be their disciple and Miu just smiled and slightly giggled and blushed on hearing Kenichi's words. That night, Miu came into Kenichi’s room and inviting him to come visit her parents’ grave to make her feel calmer.
When Miu meets Sho Kano,he falls for her at first site and offers to tell her about her father if she comes with him, causing her to choose to go with him to get answers. However, after he attacks Kenichi and friends and Kenichi shouts for Miu not to leave and swears he'll protect her, she refuses to go with Sho, but not before he kisses her on the cheek before he leaves, much to Kenichi's anger and depression.
While on the school ski trip, Miu begins to remember her mother being killed and begins to black out and develop a fever. When Kenichi would go out to find her, he would run into Radin Tidat Jihan, member of Yomi and where he held Miu for him. Kenichi would be able to get her out of there and leave her in a hiding place for safety, prompting Miu to beg Kenichi not to leave, believing he would die in the snowstorm just like her mother. When she's returned home, she at first screams out Kenichi's name only to be surprised she's back home and Kenichi is next to her changing her towls in bandages. Miu then tearfully hugs Kenichi, thanking him for saving her and for him being alive. However, Miu accidently grabs his knife wound and passes out from the pain (though Kenichi still loved the moment regardless).
At the D of D tournament, she fought with Kenichi as Team Ryōzanpaku. Their first match was against the Three-Headed Dragon Team (sponsored by the Black Tiger, White Dragon Alliance) where she revealed her special move called 'Hyōi Kazekirihane', which resembles a bird. In thier second match, they were paired against nonother than the Elder (disgised as Garyuu X). During the fight, Elder would give both them advice on their fighting styles and how to defeat him, after a long fight, they crack his mask and he admits they passed and admits defeat. During the night, Sho would try to take Miu away again only this time with more force going as far as to attack Takeda, Thor and Freya leaving them heavily injured, causing Miu to lose control of her emotions and attack widely. Kenichi would try to calm her down and, embarrassed and apologizing to Miu in advance, gropped her breasts (calling it a Ma Kensei move) to bring her back to her senses. It works and Miu slaps him silly cause of it and Sho leaves in anger over Kenichi interfearing of "making Miu his". In Kenichi's fight with Sho, Sho tries to win her over saying he loves her and only he can protect her. Miu, somewhat taken by what he said, stated she already has someone who can protect her and states she can never love someone who hurts people. She then cries while screaming Kenichi's name and Kenichi rises up to fight Sho declaring he will defeat him for making Miu cry, surprising her. When Kenichi finally wins after a long fight, she tearfully hugs him. Just as she's about shot by the soldiers, Sho blocks the bullets and slowly dies from the blood loss, causing Kenichi to promise him to always protect Miu in his place. Both Kenichi and Miu mourn his death.
As the new students of her school are revealed to be Yomi members, Miu and the others are shocked. Miu then develops a rivalry and anger with Rachel Stanley when she tries to out class her at everything and kissing Kenichi on the cheek, much to Miu's anger, making her jealous. On thier school camp trip, Miu and the Stanley siblings stop the Russian soldiers from attacking the students while Kenichi must fight Boris.
She later meets another YOMI student not long after Boris left, named Chikage and, not wanting Kenichi to fight her, resolves to fight her herself. After having witnessed Chikage's more emotional side and her talk with Kenichi wanting to be her friend, Miu decides to talk with her to be her true self. While attempting to convince Chikage to be true to herself, Chikage Kushinada accused Miu for not being true to herself as well for her glasses and hairstyle, prompting her to point out how Miu's doing exactly the same thing she is, but far longer, leaving Miu surprised. After she leaves, Miu recalls all the time the other students in the past having noted how Miu always never tried to stand out, which has Miu realize Chikage is right and, after looking at Kenichi, realizes it's cause of him she's come this far and made so many friends thanks to him. This conviction had Miu decide to show off her true beauty the next day, no longer wearing her hair braded nor wear fake glasses, prompting Chikage to be shocked and Kenichi to look at her proudly (while the male students oggle at her beauty).
It is revealed that she fights using the flow of Dou. Before Kenichi left with Shio Sakaki and Akisame Kōetsuji, they mentioned that Miu grew up witnessing fights between master martial artists which would explain why Kenichi can't seem to land a hit.
When Kenichi returns from his trip with Shigure, Miu runs up and hugs him, believing she'd never see him again, prompting Shigure to note how rude that was. Later, the Elder gives Kenichi his son's (Miu's father's) arm guards, stating the guards he got are his to keep, much to his surprise wondering if he and Miu are alright with that, which Miu happily states she's glad to give them to Kenichi, causing a development in their relationship together.
When Diego Carlo challenges Kenichi and Ma to a fight, Renka takes his place, causing Miu (who was eating with Kenichi at the time) and Kenichi to follow them to a ship. While their, they would reunite with Li Raichi and work together to defeat the Meatman and defuse the bomb on the ship. However Miu messed up with the bomb, due to her losing her focus when Raichi asked if she and Kenichi were a couple causing her to get flustered. When Diego was defeated, everyone left and the bomb was deactivated.
When Freya and her grandfather Danki was kidnapped by the Yami weapons group, Miu and the other members of the Shinpaku Alliance go to rescue her with Shigure Kosaka's assistance. As they all fight their own opponents with Shigure fighting Agaard Jum Sai on her own, Kenichi and Niijima went on their own on the truck were Freya and Danki were taken from. When Freya and Niijima escaped but Kenichi was taken and left severly injured by the Bantou Master, Miu was very worried and they left to find them. After Danki and Kenichi defeat the opponents at their location, Miu and the others arrive and hugs Kenichi admitting how glad she is that he's alright. After they went home, Kenichi was under house arrest for fighting a master opponent and Miu told him not to worry about it. She was then seen serving the other masters while they were cellebrating Kenichi's progress and how proud they were for fighting a master class fighter and defending his friends, all which Kenichi saw with Shigure helping him spy on them.
She is later shown with Kenichi and the other masters during the invasion of the Okinawa Yami base, being the few to arrive at the top floor with Apachai Hopachai, Kenichi, and unexpectedly, Haruo Niijima Before Kenichi's fight with Tirwat, she escorts Niijima to the computer room to help Koetsuji get information on Yami but heads back out when she gets a bad feeling about Kenichi and on the way defends herself from one of Yami's Bantou Master then meets up with Sakaki and meets with Kenichi saying she's glad he's alright.
When Ryōzanpaku's masters were framed by the Pro-Yami members of Congress and had to run away. She teamed up with Kenichi, Niijima, Takeda, Ukita, and Kisara to get the evidence to the government to clear the names of Ryōzanpaku's masters. She then had to fight Rimi (who has speed that could outclass Miu) to get back the disc. She thought to have failed Thor broke the disc by accident, but Nijima revealed that it was a fake for Yami to leave them alone, annoying Miu and Thor. They fight Ishida after he reveals his true nature and he's defeated by Sakaki. After all the fighting, she is present when Freya visits a recovering Kenichi, and intiutively discovers Freya's confirmed crush on Ukita. She now playfully hints toward this by making a triangle with her hands (representing the love triangle between Ukita, Kisara, and Freya) whenever talking about them.
After the incident time has pasted and the masters have yet to return. Kenichi wounds have healed and he has been getting used to it being just him and miu at the dojo he has also been doing the training regiment akisame left form him but has been multiplying it, making Miu smile while blushing at him stating for some reason she feels really happy. When he and Miu arrive at school he asks Niijima about the status of things wondering when his masters will return. Kisara teases her and asks about the time alone she's had with Kenichi lately wondering if anything particular has happened, causing Miu to blush. When Kisara asked about her doing something with him special, Miu was flustered. As they return home, Miu brings him a cup of tea and he knocks it over in the air by accident, he and Miu both react and quickly grab it before it hits the floor and end up holding hands while grabbing the cup. Both blushing too embrassed to let go they hold hands for a minute. Later that night, Miu was on the roof the same part where he and Miu have always had important talks in the past. Kenichi tells Miu that there is an emotion that he wants to put in words but, wants to save it until he is able to protect her. And tells her that he only wants to say that he has this feeling and asks if it is a cowardly thing to do. Miu tells him it isn't and if he says it like that until now without words but with action he has shown her how he feels and she kisses him on the cheek. All of the masters suddenly return surprising them both and scared by the Elder having seen everything. Apachi says he didn't see anything and the elder tells him if he wants to be with Miu he has to defeat him first. He says he knows that very well and begins training with Akisame. And that night became "The night that did not happen" in Ryōpanzaku. Since then, Miu has been under surveillance away from Kenichi. However, others have noted how much more cheerful and energetic she is and happy around Kenichi.
Due to an inquest from Kenichi, the elder revealed to her that her father is still alive. As it turns out, Miu (on her mother's side) and YOMI's late former leader, Shō Kanō, are of the same tribal lineage, the Kuremisago. This explains Shou's love-at-first-sight encounter with Miu in the past. The Kuremisago tribe customarily arranged marital bonds between men and women of their own tribe in order to create the perfect offspring and keep the bloodline pure so to speak. The love between Miu's mother and Saiga Fūrinji, peace-loving at the time, caused division within the tribe. Those opposed to the union, and their allies, fought against the couple and those who supported them. However, Saiga, who held back from killing during fights then, changed and began to believe that blood must be shed for the greater good. Eventually, he killed his wife, Miu's mother, along with all the fighters in the village before his father, the elder, could stop him. A Yomi member also refers to him as the leader of "One Shadow Nine Fists," specfically the "One Shadow." Without showing any indication of anger or sadness, Miu accepts her past with strong resolve.
She then accompanied Kenichi to watch the fight between Sakaki and Hongo. During this fight, she recognizes that Kenichi has surpasses her own "sight," that is, the ability to observe one's opponent. Although the context in this case was referring to a fight in which neither Kenichi nor Miu took part, it can be inferred that from this point, Kenichi may be able to read his own opponent now better than Miu can read her own. However, she decides to not stay behind and keeps watching. When an unconscious Hongo (mistaking it for someone else) delivers a devistating blow to Kenichi and presumably kills him, she loses control of her emotions and goes to attack Hongo in anger much to the delight of the culprit, Silkwat Junazard. She then quickly discovers that it was Junazard, who was nearby, who launched that massive amount of killing intent behind Hongo, triggering the knee-jerk attack on Kenichi. She then rushes to attack him, landing on an electrified fence but remaining unfazed due to her anger. Impressed with her technique, composition, and power due to her unleashed anger and rage, Silcardo decides to make her his new disciple. Using the Amnesia Fist technique, he knocks her out and manages to escape from Sakaki and Hongo, who both had regained consciousness and were angered that Silkwat interrupted their fight. Later, Silkwat takes off on a plane with Miu, but the plane crash lands in an unknown jungle somewhere in Tidat. Although the elder caught the falling Kenichi and saved him after all, Miu believes Kenichi is dead at this point.
Afterwards, a still-unconscious Miu "awakens" in an uncontrollable, reactive state, her body still acting in accord with the rage she last felt before Silcardo knocked her out. Still believing Kenichi to be dead, she can't control herself and starts attacking anyone who comes in contact with her. However, Junazard (showing his true, still youthful appearance), trains her in his fighting style in hopes of turning her into a ruthless killing machine full of killing intent. However, glimpses of her consciousness continue to fight within and hold Miu back from becoming such. Later, while fighting for Junazard during a takeover of one of his allied forces, she is seen and pursued by Kenichi. Although still unconscious, Miu recognizes him and says his name. Observing this reunion, Junazard believes that Miu would be completely his if she herself kills Kenichi. This idea excites him, releasing enough killing intent for Sakaki and Hongo, who are nearby working together to stop the fighting, to notice him. In addition, Miu has hesitated to fight Kenichi even after two weeks of Jenazad's training and brainwashing techniques as her feelings for him help hold her back. Sensing Sakaki on his trail, Junazard knocks out Kenichi and takes both him and Miu to another location so he can have Miu kill Kenichi in a fight to the death and keep her from breaking control again. Later, Junazard orders Miu to kill him in a death match and during the fight, she tries to break control, but continues to attack. Remembering how it worked in the D of D Tournament before, Kenichi uses Ma's Shock Recovery Technique to try and snap her out of it. Unfortunately, it doesn't work like last time. Instead, it provokes Miu even more, causing her to unleash a barrage of punches and kicks at him.
Kenichi dodges some of them and Kenichi tries Ryuusei Seikuken to see into her heart, only to see emptyness, causing Kenichi to be enraged at Jenazad for brainwashing her to a heartless fighter. Knowing words won't reach anymore, Kenich tries using the moves Mui taught him in hope of reaching her only for Miu to use a powerful move on Kenichi's face. Despite going on the offense against Miu, even using techniques from key points of their shared history, Miu continued to be unresponsive to this stimulation and overwhelm Kenichi. As Miu finally pinned Kenichi and was prime to finish him, she at the last moment stopped herself. Junazard, realizing that Miu's naturally compassion was still holding her back from killing and being completely brainwashed, he decided to take an alternate path. He unleashed a former disciple of his, Pengulu Sankan, whose failed training resulting in him becoming a mindless killer in hopes he would pressure Miu enough to kill and finally become fully brainwashed. As Sankan began to overwhelm Miu, Kenichi, despite battered and barely conscious, unleashed his "Mubyoushi" to save Miu. At this point, Miu seems to have remembered all those times Kenichi was their for her. Despite this, she still attacks Kenichi due to her unable to control herself due to her brainwash. While wondering why Kenichi fights feeling she's felt this before, Kenichi is severly struck by Pengulu in a similar manner when Hongo struck him, she remembers the similar incident and starts to collapse from the pain in her mind from confusion. Just as she's almost killed by Pengulu when he is unable to fight anymore, Kenichi stops Pengulu from killing her at the last second and her mask shatters from the impact and finally regains her senses while shedding tears seeing Kenichi again. With their combined effort, they defeated Pengulu.
Having Miu brought back to her senses, she thanks Kenichi for everything, but then becomes embarrassed after realizing she was half naked from her clothes torn up. She tried to attack Kenichi due to Jenazad's spell trying to take over again and realized she should knock herself unconscious for Kenichi's sake. Kenichi then carried her body trying to escape but were surrounded by Tidat masters and were saved by Menang and his daughter. Later, they were saved by John, who was revealed to be none other than her father, Saiga Fūrinji. When he leaves, she briefly wakes up believing she heard his voice. As Hongo's death match with Junazard is over with Junazard defeated, Miu briefly wakes up again after hearing Hongo's name and goes to attack him. However, instead she rushes over to Jenazad to keep him from dying, shocking Jenazad stating she should be attacking Hongo due to his brainwashing. After Junazard dies and Kenichi and Sakaki make it to the top Sakaki knocks her out again. As the elder arrives and thanks Kenichi for protecting his granddaughter so well, Miu wakes up again and tries to attack Kenichi again only for the elder to knock her out with a Ki move on the back of her head. The elder states they can bring her back to her senses since Kenichi managed to save her from Junazard fully brainwashing her.
At the palace, Miu is being treated by her grandfather and is eventually brought back to her old self but has a fever for now. At night, she's visited by Kenichi who asks if she's alright and she says she's glad saying she had a dream that she met her father. Kenichi smiles back and holds her hand saying they should now go back to Ryōzanpaku and to their friends in Japan.
After returning home, Miu, after several treatments from her grandfather and Kensei, she was fully out of Junazard's control and back to her old self and Kenichi noted how much closer she is to him now as a result. On their way to school Kenichi asked if she had any memories of being brainwashed but Miu didn't remember anything. When they get home, she asks Kenichi to spar with her since she hasn't trained in several days and thinks her skills are rusty, however, much to their surprise she delivers several blows all over his body and knocks him out with powerful blows to which she deeply apologizes realizing her skills have become sharper thanks to Junazard.
On Sunday, Miu would decide to go to the Shinpaku headquarters for fun and would run into Kenichi and ask what he's doing. He would explain about his meeting with Ryuto and that he had to do it alone to which Miu understood and asked for him to be safe. When she arrived at the headquarters, she would discover about Rimi's website blog and how she's saying someone named R-sama meeting someone at the aquarium. Realizing it must be Ryuto, Miu left and went to the aquarium worried for Kenichi but quickly lost focus as she became excited at being at the aquarium for the first time ever and started watching all the fish. She would bump into Rimi and the two would fight while Rimi asked what Miu is to Ryuto. Miu easily overwhelms Rimi due to her training from Jenazad and her Dou Ki getting the better of her, something Miu isn't able to understand and, as a result, delivers heavy blows to Rimi despite Miu trying to hold back noting the strength. She tried to get her gold shoes only for the octopus to grab them and force her to leave them and be spotted by Kenichi and Ryuto. She apologized to them for coming but Ryuto understood her reason since Rimi is like that. Ryuto decides to talk with Kenichi another time and Kenichi agrees and tells Miu they should leave so she doesn't get a cold.
The next day at school, Niijima would scold Miu for fighting Rimi like that and Miu thought she did something bad and Takeda would put his arm around her causing Kenichi to tell him to let go. Renka would then hug Kenichi stating she wants to experience youth herself causing Miu to try to hug him back and make her let go, causing Kenichi to become nervous. She and Miu would later listen to Kenichi and Tanimoto's talk and when Renka asks if Miu feels the same about putting her life on the line, Miu just smiles back. Later, she helps Kisara prepare for her double date with Ukita and is extremely happy to help thinking it's one of the sweetest memoris of youth. When Kisara doesn't take it seriously, Miu slaps her hands together calling her a fool that she must take this seriously like Freya did and slaps her hands again when Kisara wants to go in her normal clothes and says new clothes might attract him and Kisara realizes she's right and asks for her help in getting ready. After the date, Miu is visited by Ukita and she hears of his bad luck on the date, but Ukita is positive nontheless and says how amazed he is by Kenichi's resolve to get together with her and when Ukita has doubts about whether he desirves her or not since he isn't able to protect her, Miu asks if you love a person do you really need to qualify for that. She says that when Kenichi said he would protect her it made her very happy and knows that happiness won't fade even if he should ever quit martial arts and says thats her feelings on some level while blushing.
The next day, when she says Ukita acting out his feelings, she becomes happy and does her love triangle. She then walks hom with him and Kenichi while talking about the match and hearing Shiba's words afterwards. On the day of the fight with Ukita and Shiratori to win Kisara over, Miu walks over with Kenichi due to Kenichi's legs being weak from Akisame's brutal training despite Miu saying he's being mean on Kenichi and Shigure commented she softer on Kenichi since Tidat and blushes more. She helps Kenichi walk, however, they are being followed by an assassin. They arrive and witness Ukita loss at the hands of Shiratori while Miu comments on how strong he really is despite his rank. The assassin arrives and tries to kill them and Miu's berserker mode kicks in and starts attacking brutally till Kenichi stops her telling her she'll kill him if she continues. Just then, Ukita grabs him and they fall off the ledge. They are saved by Shiba and taken to Ryōzanpaku with Shiba commenting on how her ki has become stronger, but Miu didn't understand what he meant.
When Kenichi trains at Ryōzanpaku with Kensei, Miu decides to train to, but her Dou ki kicks in again and breaks the post she punches and bleeds from her hand. The Elder seeing this has Kensei train her at night to develop her ki for better control. The next day, Miu and Kenichi with the masters (and Shinpaku that found out) all go to a Yami headquarters but are forced to stay due to the danger. However, they are spotted by a limo that picked up the other YOMI members the other day and are shocked to see Berserker in the limo and a new member named Lugh. As Niijima reveals Berserkers decision to join YOMI she reacts shocked that his fighting style is personal style noting how it's similar to her grandfathers. As Lugh sets his sight on the alliance, Miu tries to tell him about Ogata's usage of his disciples, but Lugh is fully aware prompting Miu and Kenichi to prepare to fight him only for Ukita to strike first but be saved by Siegfried. She becomes shocked to hear from him that Lugh is blind and is horrified when Sieg has his neck snapped only for him to snap it back into place. She later watches as Takeda decides to step in to fight and wishes him to be safe. She notices Lugh's fighting style makes him able to hear the vibrations of the human body and how his fighting style is advanced to expert level. As Takeda attempts to sacrifice his left arm, Miu stands on the side telling Niijima that it's a one-on-one fight and can't interfere. However, Kenichi steps in to save them and Lugh decides to leave (due to him sensing Shigure coming) but promises to take Takeda out first next time.
After returning home, Miu ponders over Lugh's skills and realizes he sensed Shigure's presence from before and tries to do the same. She attempts to sense a presence around her and tries to guess it's Sakaki or Akisame, but it turns out to be non other than Tsutomi Tanaka, much to her surprise. She and Kenichi greet him as he wishes to talk to the masters. Later, as Kenichi trains and Sakaki beats him to a pulp Miu yells as Sakaki for going too far and tends to Kenichi as Kenichi asks why she's not coming to the amusement park with the Alliance and she states she wants to but has a lot of things to do and her training with Kensei and Akisame to do and her afteraffects from Tidat are still affecting her. As Apachai comes in having told her he did laundry she at first gets upset that he might of ruined the clothes but becomes surprised they are all clean, much to her relief that he was in "secret training". With that, Apachai tells her he'll to the chores so she can to the amusement park and gets excited that she can go and starts preparing.
At the amusement park, Miu starts just hanging around with Kenichi, but due to her happiness of hardly never been to an amusement park so much in her life she runs fast leaving Kenichi in the dust. As some boys stare at Miu commenting on her beauty, she realizes she lost Kenichi and then sense a strong ki and jumps into the water wandering if its from the side of the pool. She then is found by Kenichi as she stares at the merry-go-round and Kenichi notes she wants to ride it stating she's always wanted to ride one when she was little and Kenichi and Thor note she gave up a lot during her travels with her grandfather. Kenichi states that it's because of this that he met her and grabs her arm and tells her they should ride it together despite her hesitance. While riding it, she blushes from Kenichi's enthusiasm from the ride for her sake and admits her happiness from waving while on a ride rather than on the side feels good for a change. At night, she is attacked by Lugh and Rimi while grouped with Takeda. As Takeda tells her he'll fight Lugh, Miu prepares to have her third match with Rimi.As she fights Miu is shocked to see how much stronger Rimi is since the last time and how her attacks are so heavy and her own attacks are losing to her. She notes her speed and skills have increased since last time and how she's a different person. She continues to guard from her and becomes shocked to hear that all the other members of YOMI are hear also. As Rimi continues to overwhelm her, Miu resorts to taking her limits off her martial arts and attacks Rimi with her Dou Ki, only this time in control. Miu states that now she has to go all out and that her travels have made her fight many thugs and made sure she didn't hurt them so much and notes she can't hold back so much against Rimi this time. They continue to fight as Rimi, realizing Miu's still holding back her true strength takes her gold shoes off and runs at Miu only to be angry that Miu runs past her after the gold shoes again. She finally gets the shoes only for Rimi to grab them right back and throws them on top of a castle.
Miu then resumes her fight with Rimi and states that the Satsujinken causes damage to Rimi's loved ones, but Rimi retorts stating to gain power, one must be willing to take risks. Rimi intends to prove her training from Ogata and charges at Miu with blinding speed kicking Miu in the back and tries to attack Rimi only for her to dodge her while attacking her from behind again and continues to overwhelm Miu with several blows, prompting Miu to wonder if Ogata's training was really effective. A roller coaster ride arives and she gets on it and continues to defend herself from Rimi as she marvels at her new strength. As Rimi prepares to end things, Miu breaths in and unleashes a new move she came up with having control over her Dou ki and knocks Rimi down. As Rimi tries to believe she was faster, Miu says she was and that she decreased her strength to increase her strength. She then reveals she followed Rimi's movements from how strong her ki was and that her ki scatters, so does her heart and makes her distracted and kicks Rimi backwards into the water. As Rimi demands to know if her training made her stronger, Miu says she just learnt to do it now.Confused, Miu admits her having trained in martial arts all her life yet has never fought someone who was her age and have a hard time against. When Rimi asks if Miu would ever sell her soul for power, Miu seems surprised. Rimi then decides to go all out and releases her Dou ki, prompting Miu to recall the dangers of Dou ki from Sakaki and Apachai's and how dangerous it is. Rimi then unleashes her Dou ki and overwhelms Miu to the point she can't dodge Rimi's moves anymore and notes how heavy they are and it's very dangerous, but is unable to dodge and gets hit with a brutal punch into the water. Rimi then approaches the fallen Miu and says it's her victory and delevers a powerful punch into Miu's back and she crashes into the water. As she prepares to finish Miu with Ogataryuu Datotsusenpa, Miu, wondering if she's going to die and recalling her training with her grandfather, suddenly activates her Dou ki berserker mode after her near death experience and blocks Rimi's blow and sends her backwards. She then punches Rimi back and the two, having unleashed there Dou ki causes them to fight in a wild frenzy all after going through the other YOMI fights with Shinpaku. They make there way to Ryuto's and Freya's location still fighting wildly as Miu seems to gain the upper hand as she loses control. Miu continues to fight wildly, having lost control of herself as she continues to overwhelm Rimi. However, Rimi tells Miu the world of martial arts isn't so cut and dry that victory is determined by ones release of ki and deals a two-fisted punch in Miu's stomach, sending her back. However, Miu ignores her damage prompting Rimi to berate her for ignoring it more over Miu trying to damage her instead. Miu then charges with fury and gets behind Rimi as Rimi tries to swing her arm around as Miu jumps up unleashing a fury of fists only for Rimi to dodge them at the last second. Miu then runs to the other side of the peer and Rimi retreats and Miu rushes at her full speed striking her as they strike back and forth as Rimi notes Miu's ki surpases her and if she makes one mistake she'll be done for. Rimi still refuses to lose and when Miu strike with her fist, Rimi pushes it upward and tells the berserk Miu that the proper usage of ki always surpases those that use it wildly and thanks to Ogata's training will help her win her fight and delivers' point blank attacks on Miu's face.
Miu continues to ignore the damage and they fight onward making there way to Kenichi fighitng Berserker as Miu is dealt a kick to her face. She recovers on a roof and continues to ignore her damage as Rimi coontinues to dominate her with severe blows leaving Miu unable to defend, something Kenichi notes is cause she's trying to supress her full potential less the other personality Junazard made will take over. Rimi then deliver's a devistating blow to her face which causes Miu to cough blood up and crash into the roof of a building. Almost unconscious, Miu is then yelled at by Kenichi to open her heart and listen to him. He tells her to not be afraid of her ki or the curse from Junazard, siting the elder's quote "Do not spread your wings halfheartedly, but fly with all your might". He goes on saying that though he has Sei ki, he's sure that beyond the curse of Junazard lies the answer to control her Dou ki. Rimi takes advantage of her limp body and throws Miu into the air, crashing into the merry-go-round as Kenichi shouts for her to fly and he'll be by her side. Still not moving, Rimi tells them both words won't reach her and strikes her face only for Miu to have regained consciousness, blocking the blow at the last second and strikes Rimi's sides swiftly. Miu then stands, having finally returned and now in control of her Dou ki with a new look in her eyes, smiling at Kenichi.
Having finally gained control of her Dou ki, Miu turns the tide of the battle in her favor and continuously overwhelms Rimi with blows all over Rimi and states it's due to her training under Junazard that she's able to control so much Dou ki. Rimi continues to attack only for Miu to counter and slam her down with a Silat move. Rimi still attempts to attack her and after seeing an opening, attacks Miu. However, Miu easily got past her and landed several blows afterwards. Rimi then falls hitting a poll to the ground, seemingly defeated in disbelief over Miu controlling so much Dou ki, to which Miu states it's cause of Kenichi she's able to. Just then, Isshinsai Ogata arives, surprising her and as Kenichi approaches him, she tells him to back off and is shocked to see him thanking Ogata instead. After he walks back, she notices he's fighting Berserker and then is surprised to see Rimi demanding to fight and asking Ogata to teach her "that technique" so she can still fight. Despite her's and Kenichi's attempts to stop her, Rimi uses the Seidou Goui technique to continue fighting via Ogata's permission. Having her strength increased further, Rimi regains control of the battle and overwhelms Miu to the point that if Miu hadn't used her Dou ki at max to defend herself she would have died. As Rimi continues to toy with Miu she wonders how can she defeat an opponent so strong without killing her and if this is the limit of the Katsujinken.
Knowing the danger of Rimi's current condition, Miu surmises that one of them will die if they continue to fight in there condition. As Rimi attempts to finish her off, both deal one final powerful blow to the two as Ryuto desperately tries to stop Rimi and catches her as Kenichi catches Miu. However, while Rimi regained her senese before she struck Ryuto, the negative affects of Seidou Goui activate and Rimi coughs blood up and passes away in Ryuto's arms. Shocked, Miu laments her inability to save her while Kenichi tries to comfort her. As Ogata regards Rimi's death as a pity and a "noble sacrifice" over how he'll use someone else next time, Miu attacks Ogata in furry only for Ogata to easily block and strike her torso with a fatal blow. Miu flys backwards as Kenichi catches her as she vomits blood and passes out from her injuries.
Comming to, she watches as Kenichi and Ryuto face off against Ogata, pleading Kenichi to stop and watches in horror seeing Kenichi struck by Ogata. She then is shocked by the appearance of Tanaka saving Ryuto at the last second as he faces Ogata now. Watching the masters fight and seeing there desire's to win, Miu and everyone else is shocked to learn that Ogata didn't just murder his master, but his wife and unborn child. As the fire gets closer to her, Kenichi saves her at the last second, prompting an impressed Tanaka to tell him to protect her. Despite Tanaka's best efforts, Kenichi and Miu watch in horror as Tanaka is killed by Ogata with an elbow crushing his head. With the fight over, Ogata and Berserker leave while Ryuto stays behind with Rimi's body. They are later found by Niijima and Renka and help take them away from the park.
Following Tanaka's death, Miu and Kenichi go and visit Ryuto and the now recovered Rimi at the hospital, to which they (unintentionally) interupt Rimi's attempts to be with Ryuto. Ryuto says there fine and they converse how Ogata actually saved Rimi's life when checking her pulse but really was stoping her flow of ki at that time. A couple of days later, the masters talk about the subject of how Tanaka's fight with Ogata was unavoidable, and how they need to find a way to help Kenichi and his friends with their fight against the weapon users of Yami. They all agreed that they would eventually fight the weapon division on a frequent basis, which is when Shigure comes up with a plan for helping the Shinpaku Alliance, a plan which she calls the "Shigure-chan Special". When asked about her plan, Shigure says it's a secret, prompting Kenichi and Miu to wonder if it's a type of hellish training for the alliance. Wondering what her plan is, the two follow her and Apachai to gather sand from the sea. They then go to a house that Kenichi remembers and is greeted by nonother than Kagero Sai and as he and Miu believe he's going to fight the alliance and when they think he's going to attack them, he goes right past them and instead picks his sprout plants, much to there shock. When Shigure gets some dirt and a device for moving water in a canal and Miu realizes Shigure is using a metal flow while Sai states she's right and it's used for forging metal, as Kenichi and Miu realize she's providing arms for the alliance. Shigure corrects them and says she's making armor for protection and when she says it will take a week to make, Miu leaves with Kenichi.
Following the week, the elder leaves on a trip to which Miu tries to convince hiim not to, but says those with great power must fight for justice and says he'll be back soon. Kenichi tries to comfort her, only to hurl him from behind by accident. Miu and Kenichi meet up with Shigure and Apachai to which when Miu tries to wake her up, her clothes are shredded by Shigure's self defense, much to Miu's embarrassment. She is given a towel and watches in amazement seeing how strong her arm guards are for the alliance.
Later at Ryozanpaku Inspector Honmaki arrives with news that starting tomorrow, the police force is to guard Yami during a meeting in a governmental building, greatly shocking everyone. While the other masters comment on how their influence has reached in the government and all resolve to lock them in Big Lock while Miu wishes the elder could witness this, Kenichi reassures her, while taking her hand, that he'll return with a smile. As Miu smiles back, Kensei slap their hands away stating he swore to the elder he'd keep their relationship "moderate". They all then proceed to each lunch together and prepare for tomorrow.
The next day, after the masters go off to face Yami (minus Shigure), Miu wishes them luck along with Kenichi wishing her grandfather was hear and that Kenichi should protect her too, to which she becomes upset when Shigure says the same. Later, when Shigure tells them of the man she saw on tv that has a weapon her father made and her hesitance to go after him, Miu and Kenichi encourage her to do so. Knowing she can't leave them alone, Shigure brings them along to which Miu notes that it's better than waiting for everyone to return. They all then go to the Tokyo docks without the coast guard catching them. While searching, they find two bodies who are still alive and Miu treats them the best she can. Afterwards, they follow the trail the man left behind and manage to board the boat before it leaves. However, Shigure notes that there are seven people on board, and they are all the members of the Hachiou Executioner Blade members.
As helicopters surround the area, Miu notes how rowdy it's getting. As Shigure notes they've likely been spotted, Miu notes they've been exposed by the armed members. They are then found by Michael Schtilvay who prepares to fight Shigure. As Shigure appologizes to the two over the situation, Kenichi and Miu agree to not let her worry and that they will work together. Though moved, Shigure tells them as her master to find a way to escape. Miu reminds Kenichi of them working together like that time in Tidat, to which Kenichi notes it will be much tougher than that time.
As Shigure engages all the weapon's users, Kenichi and Miu take this opportunity to run away, only to be blocked by Michael. When Seitaro raises the black flag of Yami, Shigure slashes open one of their contaner's to reveal gold bars. Miu exitedly marvels at all the gold wanting to take some of it, prompting Kenichi to note she's too excited. As Shigure continues to fight the Bow Master and Michael holds her and Kenichi hostage, Kenichi wispers to her to run when he makes an opening. After he distracts everyone by dancing, they make a run for it while Miu complains not getting some of the gold. They are blocked by the Armored Knight and Michael reengages them and chooses to kill them both. Despite their efforts, they are no match for Michael and are saved at the last second by Christopher Eclair and Mycroft.
She and Kenichi then watch as Christopher and Mycroft, after having been ordered by the Japanese government (and payed by Shigure with a gold bar) engage Seitaro and Michael in battle. Once Shigure tells Mycroft and Christopher to take Miu and Kenichi away, Shigure gives Miu tochumaru to escape with. Once Shigure uses her Soutou Kyourenzan allows Miu and the others to escape. She was seen on an escape ship watching worried as Shigure was defeated by the weapons division.
Back at Ryozanpaku, as Sakaki scolds Christopher for not saving Shigure, Miu and Kenichi thank Christopher for saving them, much to Sakaki's annoyance. They later go to the Shinpaku Alliance headquarter to inform everyone of what happened. Once everyone questions the actions of Yami, she agrees with Kenichi about fighting Yami when the time comes. Just then, Kenichi questions Miu on the wereabouts of Tochumaru, to which Miu shamefully admits he's been missing since they escaped the tanker and Miu answers that Tochumaru escaped her grip and stayed on the ship.
While at school Kenichi and Miu are running a marathon for their school when Kenichi is kidnapped. Miu tries to catch up with them but loses them. Luckily, Akisame anticipated this knowing Yami would go after Kenichi and flips the car saving him. After interigating the man through Akisame's and Sakaki's rather frightening methods, Miu, Kenichi, Akisame and Sakaki run on rooftops and arrive at an empty train station. They hear voices stating they are glad the targets have been brought to them as the masters tell Miu and Kenichi to stay back. Weapons are thrown at the two as they dodge, though the electical wires are cut and is now dark. The two attackers are happy to encounter such able opponents and introduce themselves: "Francisca Freaks" Sherman Camus and "Scramasax Master" Cedric Casken. They watch as Akisame and Sakaki fight the Yami weapons users and are both surprised how calm the opponents are. However, they are defeated once Sakaki and Akisame go all out. Just then, they are visited by an individual named Okamoto who works in the government. He reveals a person named Kiyoi Kidou who may be able to help them.
The following day, they consult Niijima's assistant and find Kiyoi's location. They visit her and discover she is blind and the younger half sibling of Rin Tachibana of the Hachiou Executioner Blade, but they note she has no ill intents to them. After revealing a phone her brother uses to talk with her, they discover it's impossible to make calls for themselves on it. However, at that moment Shigure calls them to which Miu jumps for joy at this revelation. Just before the connection is destroyed, Shigure is able to give her location to them. After gaining her location, they all leave and greeted by Okamoto, who reveals to have been tapping in on the lines and wishes to help them.
Miu is later seen with the rest of the Shinpaku Alliance with Okamoto on their way to the Yami base to save Shigure. While traveling, Miu is sparing with Kenichi in the mean time, to which Okamoto also engages in training with all of them as he points out where they need improvement in. Miu laughs noting how similar his training methods are to that of the Ryozanpaku masters, to which Kenichi sheepishly agrees. Later, Okamoto has them all resting for later, to which others question if they can trust Okamoto, to which Kenichi says they can if it will save Shigure. At that moment, Miu apologizes to Kenichi about dragging him into the world of martial arts. Just before Kenichi can rebuff her statement, Takeda interrupts stating he needs to tell everyone, especially Miu something he heard from Sho Kanou a year ago: that Miu's father, Saiga Furinji, is the leader of Yami. As most react shocked, Miu shows little surprise, noting she always had her suspicions and that her father may have really murdered her mother, to which Kisara tells her not to think so gloomy about that.
Miu asks everyone if they are ready to go to war, to which they state they are martial artists and are always ready. When asked by Takeda if she's been in a war, she replies at least twice, but not one this big, much to the shock of Takeda and Kenichi. In a serious tone Takeda tells Miu that it won't just be Kenichi and Shou Kanou who will risk their lives to protect her, and Takeda and Kenichi meet eyes. Kenichi then brings up his earlier conversation with Miu and says that he does not regret being invited to the world of martial arts because he was able to meet all of his friends, which makes Miu smile at his response. Just then, Okamoto enters and tells them to get ready as Miu and the others get ready for battle.
- In a good portion of her fights, Miu's cloths get ripped in some way by Master (or Disciple) Class Fighters.
- Miu bears a heavy resemblance to Street Fighter character Cammy White and shares quite a number of traits with her: both have blonde braided hair with a bang sticking from the top, blue eyes, a fondness for cats and similar looking fighting styles.
- Miu is one of four girls that has fallen in love with Kenichi. The other three are Renka Ma, Li Raichi and Yūka Izumi.
- Miu's dream is to become a beautiful bride. Ironically, her dream of becoming a beautiful bride is made extremely difficult by her grandfather's unreasonable declaration that Kenichi must defeat him in order to be with Miu. This is made more ironic due to the elder only being concerned for Miu.
