In the suburbs of M City, a town full of people with unusual personalities, all kinds of extraordinary slapstick incidents are taking place on a daily basis. Gambler Itou Kaiji lives as a NEET and is treated as a useless member of society by the people around him, but he is unable to reform. In the meantime, Akagi Shigeru (13), Akagi Shigeru (19), and Akagi Shigeru (Man of the Divine Realm) are living as part of the Akagi residence and causing trouble around them.

In addition, the old villains including Hyoudou Kazutaka and Washizu Iwao are enjoying shady events at the retirement home Espoir, while Hirai Ginji, the head of the neighborhood association, is scheming to make money, and genius boy Ukai Zero has confrontations with Shirube at the arcades.
