The War Begins!!

Summary
The Sket Dan/Yabasawa team recruits Shinzō to be their fifth member and registers for the competition. The Student Council registers at the same time and are followed around by Shōnen Jump editors tracking their progress for promotional purposes.

Both teams blaze through the preliminary rounds and meet at the final, where the five rounds are announced: a cooking battle, a fighting game, a shooting game, a dating simulation game, and a mystery card game. Bossun decides on a perfect contestant order for the games, but Yabasawa gets a call informing her that her brother was involved in another accident and that Yeti has run away again. She leaves, and the Sket Dan team is forced to call in another member or forfeit. Himeko tries to contact Momoka while Bossun, under pressure, switches the contestant order randomly.

First round: Himeko vs. Michiru, in the Cooking Colosseum.
