A coming-of-age story about a delinquent boy and an honour student girl, two people who never crossed paths, and how they grow into their true selves through ‘monsters’. The protagonist is delinquent Nishiura Kazuren. He develops a crush on his classmate Fukatsu Yuki and decides to change himself for the first time. However, Yuki is an elite student with good looks and top grades. He has nothing to do with the delinquent Ren. But he really wants to be with her. He has no choice but to rely on God, so Ren makes a wish at a shrine.
"Please make me the type of girl she likes". His wish came true, and the next morning he was transformed into the type she likes – in the form of a monster.
