Akira Shiroyanagi 白柳啓

Akira Shiroyanagi is a high schooler who loves games and Konpeito. He is bored with his everyday life and hence tries out many games hoping to find something to challenge him. This changes when he suddenly is dragged into a battlefield by a mysterious girl who calls herself Mion. The participants are told that they were "erased from the family register, involved in an experiment, and gained certain powers." They then have to compete against each other in varying matches.
