Juzo Ogami, a legendary hit man, faces his toughest assignment yet: surviving middle school. After a mysterious insect bite reverts him to a teenager, he must navigate the treacherous halls of adolescence while his old life keeps pulling him back.

During a double date, Ogami suddenly transforms back into his middle-aged self, and Noren is abducted right under his nose. He tracks her captors to a deadly encounter with two operatives from the world's largest murder-for-hire syndicate, forcing him and Tenma into a desperate rescue.
