金森 義仁

Marie's homeroom teacher. He is a lively and popular teacher among the girls... but he keeps a wild animal inside of himself, and Marie becomes its outlet. Initially, he was ambitious and idealistic, but Kanamori attributes his changes to cracking under various pressures as well as being disillusioned.

Kanamori becomes paranoid about Marie eventually revealing their "relationship", and strangles her to death when she tried to confront him (Marie planned on reporting him to the authorities, using the video recordings Kanamori made as evidence against him).

He was competing alongside Marie in the hopes of becoming Meso-Meso, but was killed because he broke the rules of the "game" (speaking to Mesomeso-san). In the end, Marie became Mesomeso-san and crushed his entire body into dust.
