Satoshi, who suffered severe burns while rescuing him. Though he's
convinced that his parents were murdered, Maki has no clues to help him
find the culprits other than the hazy memory of a certain symbol.

society called Premium that's based in Tokyo University, Maki enters the
same college, hoping his top credentials will get him an invitation to
Premium. He isn't chosen, but the more socially adept Suzuki is. Maki

embark on a hunt for the truth.
