Tenkabu!

A new student named Hideyoshi Hashiba is drawn into a strange situation when Nobunaga Oda, a loud and clumsy girl, insists he join the Tenkafubu club. The club's goal is to "unify Japan," and its members act out a chaotic, humorous version of Sengoku-era themes. The story features a group of eccentric characters who perform a bawdy, over-the-top parody of historical figures and events.
