Kill Blue

Mysteriously transformed into a kid, hitman Juzo poses as a student to investigate a middle school; he encounters a suspicious intruder.

Juzo discovers Mitsuoka Pharmaceuticals created the wasp and befriends the president's aloof daughter Noren; as he slowly befriends her, she's kidnapped.

Juzo turns to a classmate to catch up on his studies and joins the home economics club with Noren; Mitsuoka Pharmaceuticals makes a big announcement.

Juzo's cover as Noren's boyfriend comes under fire when a young assassin transfers in and challenges Juzo to a duel in a bid to become Noren's fiancé.

While on an errand, the Home Economics Club runs into Tenma, a brash multi-sport ace who challenges Juzo to a futsal match; will Juzo take him on?

Even as Tenma overwhelms the Home Economics Club in their futsal match, Juzo earns his respect, forcing him to drop the handicap and go all out.
