The One Shadow, Nine Fists are the ten most powerful unarmed combatants of Yami and the leaders of the Hand-to-Hand Division of organization. Each member is a master's of different Martial Art and promotes the Satsujin ken (The Killing Fist) as their belief of what true Martial Arts are meant for. Each member also has a disciple, whom they have personally trained and who each make up the ten strongest members of Yomi. Each member is assigned an element as their symbol, which their disciples in YOMI use as well. Despite being working together, they do not get along well, with Silcardo saying the only reason they have come together is so that they can avoid fighting each other.
Also to note are the names of the nine Fists with regard to their degree of cooperation with Yami. Masters such as Silcardo Jenazad, Agaard Jum Sai, and Ma Sougetsu have only "Fist" to show in their names while their titles speak of themselves not as "Fists" but as "God" or "Sovereign". In stark contrast are Ogata and Alexander, who are both "Fists" and cooperative with the other members of Yami.
There are currently seven active members; Alexander Gaidar and Diego Carlo were defeated and sent to Big Lock and Junazard was killed in his death match with Hongo. Agaard was defeated, but Yami's control of the government at the time saved him and deported him to back Thailand; he has recently made another appearance uninjured and seemingly active.
While not much is known of this group or its members, they are a very powerful group, noted by Shio Sakaki to the Armed Division counterpart to the One Shadow, Nine Fists and the top division of Yami's weapon users with both sides being equal in power. Likewise at least one of their members has two students, though it is unknown if this division has the same standards of selection as the Nine Fists or if the disciples of the Hachiou masters have formed a sub-division aswell.
