Not so much a single technique as Kenichi's ability to fight with his masters styles, allowing him to use all of his martial arts to their absolute peak. When using this technique, an image of whichever master he's copying appears over him. His imitation is so flawless that he even adopts some of their character traits and personas, such as Apachai's habit of saying Apapapapa, Sakaki's confident and cocky demeanor, Kensei's battle cry of Chowa, Shigure's speech pattern in pausing between words and Akisame's squinted eyes and calm philosophy. In other words, it is almost as if he becomes each of his masters.
When using this, he can also use each of his masters signature or special techniques (albeit, not with as much effectiveness as when the actual masters perform them due to Kenichi's differing levels in skill) such as Apachai's Apapunch and Chai Kick, Shigure's Kousaka slash and Akisame's Idori. His masters have shown themselves to be invariably impressed, amused, ecstastic or horrified at each others' and their own imitations. This ability is not limited just to fighting styles as he once used this technique to copy Kensei's "ecchi mode" when fighting against Raichi due to his vow to never hit a women. According to Siegfried and Miu's observations, whenever he activates this ability, his spirit changes to match his masters. This technique was first used against Ryuto and even Ogata has praised this technique for is dynamic nature. According to Hayato, the reason why Kenichi can use this technique is because of all the brutal training his masters have forced him to go through as humans will remember even the most horrible memories even when they hate them. (Also noted is the fact that his eyebrows change to whomever he is imitating)
