Suigin Riku, a high school student and gamer, attends the renowned Shinryou Private Academy, a school for the elite and children of the affluent. But Suigin is neither rich or wealthy; in reality, he is dirt poor and must work many part-time jobs to pay for his tuition. During one such task, he leaps into a pool to save his favorite cat, despite the fact that he is unable to swim. Rei Riku, the gorgeous and popular daughter of a game creator, saves him, and he falls in love with her. He is also attracted to another girl: a new acquaintance he meets in Dungeon Century, his favorite online role-playing game. However, he is aware that the game is about to be terminated.
