Zenkichi visits various clubs of the school, which builds up the reputation of being a "club crasher". An upperclassman named Hisshuu Kanoya, who plans to enact revenge on Medaka for winning against him in the student council election, tries to recruit Zenkichi in his cause to form a rally against Medaka. However, Zenkichi rejects the offer and stands firm as a member of the student council. Nekomi Nabeshima, captain of the judo club, requests Medaka to find a suitable successor among the members. Kouki Akune, nicknamed the "prince of judo", is revealed to be very much in love with Medaka. After it is shown that Zenkichi and Akune have been longtime rivals since childhood, Nabeshima challenges them to have a judo match, in which the loser will join the winner's club.
