During the early days of Housen Academy, a massive brawl erupted among the students, leading the top man at that time to implement a unique rule. Any student who lost in the fight was required to shave their head, while the last five standing were deemed victors and appointed as captains in the school's army. This rule of shaving heads, except for the leaders, has become one of Housen's defining characteristics, earning them the moniker of the "Skinhead Army."

Sachio Ueda, along with Ozawa Hitoshi are watching before it starts.

Sachio: Order them to start, Jin-Jin.

Jinkawa: YOU ALL, GO!!!

Sawamura: It looks like they have great potential as potential captains like us.

Yuken: You're probably right.

Shidaken: I can't wait to see those kids bald!

Monji and Sabakan, the duo sophomores, just stared at each other and saw the new Housen students, including you, fighting for the title of captain.

All of Housen's students, including you, are currently involved in a massive fight. Make sure you win so you don't go bald!
