Bobobo-bo Bo-bobo (2005)

Season 1: Episode 19

With saving Beauty still on their mind, Bo-bobo and team prepare for one-on-one fights with The Battleship Five Quartet (who still number in six). Gasser fights first, having to go through a masked school filled with friends, enemies and sumo wrestlers until encountering an old ally turned rival. Then, Bo-bobo takes on a calendar who's afraid of losing all its pages...but it may not be the real enemy he should be worried about!
