Togusa

Togusa no Kandakara (十種の神寶, Tokusa no Kandakara) is one of the main characters of the series. His inscription as a half-Katana is Yatsuka no Tsurugi (八握の剣, Eight Grip Sword) but he detests that name, instead going by the nickname his squad members gave him. He is the only Katana-human hybrid seen in the series.
