Haiji Miyamoto, captain of the Karate Club, had challenged Wataru to a fight. Wataru quickly accepted his challenge and defeated him. While Moka was helping Wataru on his homework, They both had given into their urges and had sex with each other. Deepening his relationship with his other girlfriends, Wataru also had sex with Kurumu and Mizore later on. The next day when Wataru was walking towards school to check on Haiji, Gin jumped him from behind and angrily gave him a headlock, knowing that Wataru got laid three times in one day. Meanwhile, the girls are reporting their mothers about the change in their relationship while Moka called Wataru's mother about her relationship as well and had earned Maya's blessings.
