Morikawa is a minor character in As the Gods Will, a student at the same school as Shun Takahata and a member of the student council. He first appears during the second deadly game, in which participants are forced to dress as mice and ring a bell attached to a giant Maneki Neko. Morikawa attempts to assert authority by ordering Shun and Ichika Akimoto to put on the mouse costumes, but they refuse to follow his command. Beyond this interaction, his role in the story is limited; he is one of the many students caught in the lethal games, and no further information is available about his background, personality, deeper motivations, relationships, character development, or any notable abilities. His fate after the second game is not described in the available material.
