Tenkabu!

Hideyoshi Hashiba transfers to Sennokuni High School, and he is immediately noticed by Nobunaga Oda, the brash but dum b girl sitting next to him. She forces him to join the Tenkafubu club, a club that aims to "unify Japan"... A big, dumb comedy performed by a bunch of Sengoku-style weirdos! (Source: Kadokawa, translated)
