1•2 no Ahho!!

This manga centers on the supervisor of the Yujo Gakuen (Friendship Academy) baseball club and its lone member, Sadaoka, as they cause all manner of mayhem! Featuring cameos by various baseball players, singers, and even characters from other manga, this comedy's use of current events and biting satire made it a true trailblazer.
