From the scene that took place the other day, several girls (also known as a ko-gal group) immediately began to voice their acceptance in having Maki join their circle of friends. The group include Yuu, Michiru, Mina, and Renge. Maki was nicknamed Maki-chan.The ko-gal group planned an outing to a pool where they could showoff some new and very revealing bathing suits. A few days later, each of them were modeling their new bathing suit. During the pool outing, a girl named Kaori Sakiyama also noticed the girl and became jealous, challenging the entire group to a swimming match.
Sakiyama Kaori, ein selbsternanntes zukünftiges Supermodel, fühlt sich gedemütigt, weil im Schwimmbad alle Augen auf Mina und Maki gerichtet sind. Deshalb fordert sie Maki zu einem Kampf heraus – an einem Ort mit wenig Bewegungsfreiheit.
