Kaoru Namikido

Description

An oni in the reconnaissance unit who is disguised as an ordinary librarian. He activates his Blood Eclipse Release by shaking a vial of his blood. The blood echoes back, giving him the locations of nearby people and the layouts of buildings, much like animal echolocation. Additionally, anyone can use his power by shaking the same vial, though there are certain restrictions; one such restriction is based on a person's IQ.
