Saika



Saika is an ancient, powerful entity who is manifested in a sword. It loves humans very much a expresses its love by taking control of other people and causing them pain. Although it is powerful, Saika can be suppressed by people that it is attempting to control if they have strong enough feelings to prevent it from overtaking them. When Saika stabs someone they become one of her "children" and follow her ideals; in theory if the original Saika is destroyed then the "children" will be put back to normal.

Saika was very interested in making Shizuo Heiwajima one of her "children" because of his massive and near inhuman physical strength.

Anri claimed that she was the parasite of Saika.
