Hamaji

Takuma, Hinata, Yui, Hamaji, and Maki go to the beach together to have fun, but before long Hamaji's younger sister Yukiji shows up and tries to take Hamaji back home. In the end, Takuma and the others agree to let her stay, though for a while Yukiji attempts to hurt (even kill) Takuma or otherwise separate him from the others due to her love for Hamaji. When Yukiji is confronted by the others about Takuma, she runs away and swims in the sea, but when her leg cramps, it is Takuma who attempts to save her, though he nearly drowns himself. Hamaji has to use CPR to revive Takuma, (strangely in slow motion) and Yukiji thanks Takuma for saving her while he was florid with Hamaji's CPR. While taking a bath, Takuma finally realizes that Hamaji is actually male. Hayami comes to the beach to ask Takuma about his true feelings, but they get interrupted by Hinata.
