The Student council and SA are supposed to organize a party for the school's foundation day, with Kei and Hikari representing the SA. Kakei's behaviour towards Hikari is pissing off Kei. He angrily challenges Hikari, and the two of them split into two teams. Hikari teams up with Kakei and Akira, while Kei is working alone as always. Hikari realizes that things shouldnt be like this. She asks Kei if he would like to work together, because fun things should always be enjoyed with others. Kei agrees at once and the party turns out to be wonderful.
