Kouhei Kakishima

A research professor who was Nijuu Mensou's supervisor in Nijuu Mensou's days as a scientist.

[Spoiler] Though he warns Chiko against trusting Nijuu Mensou, he is actually obsessed with obtaining Nijuu Mensou's legacy as a researcher and reaching the "fourth state of water". He does not care for the consequences and believes that the dangerous power of the fourth state of water will change the world, no matter how destructive it is. He also used Seiji Tamiya's research to create enhanced cybernetic bodies for himself and others, eventually changing his body in the image of Nijuu Mensou. Kakihara was the original Nijuu Mensou, but Nijuu Mensou's thefts began occurring at the same time and the name became attached to the young scientist while Kakihara was forgotten. He is without morals and seeks only to complete the research Nijuu Mensou conducted before the war, believing the research was selfishly kept from him, and had killed many people over the years to obtain it.
