Giriko

Giriko is a Demon Weapon and an ally to the witch Arachne. His existence revolves around fighting, and likes to be destructive. Giriko transforms into a chain saw in weapon form. Although he is a weapon like Tsubaki or Soul, he openly states his disgust for Shibusen, claiming that he wishes to follow his own path instead of being used by a meister. Giriko fails when it comes to remembering faces, as seen when he does not recognize Maka when she infiltrates into Arachne's castle with the other Shibusen students.
