Tsubakiyama chases his pet squirrel onto the Second Years' lawn but balk at punishing him when Momotaro appears. The instructors are concerned at the Second Year's cowardice. Principal Edajima calls back the former head Second Year student, Akashi Gouji to take on Momotaro. On his return he invites the First Year students to a 2nd-Year head's Reinstatement Ceremony. After humiliating the former acting head Edogawa and some First Year students, he engages in a sword fight to the death with Momotaro. The Principal decides to use the fight as an opportunity to stage a public contest on Ganryu Island. The school then sells tickets to raise the necessary funds to pay the school's bills.
