Suisou Academy (水槽学園, Suisou Gakuen) is the main setting for the Medaka Box spin-off, Good Loser Kumagawa Gaiden. Considered Japan's foremost prestigious school, Suisou Academy closed one month after Misogi Kumagawa transferred in.
Kumagawa transferred into Class 3-4, suggesting that Suisou Academy has at least twelve classes; four for each year. Given the academy's reputation however, there are likely more classes.
The standard men's uniform of Suisou Academy consists of a dark green jacket and matching pants. The jacket has a white collar and five yellow buttons. The standard women's uniform of Suisou Academy consists of a green jacket and matching skirt. The jacket has a white collar worn with a yellow bow, white sleeve-ends, and a white fur lining at the bottom. The jacket can come in both a short-sleeved and a long-sleeved version.
Jakago's Student Council
The Suisou Academy Student Council holds a great deal of power within the school, thanks in part to the abilities of its president, Aki Jakago. Considered the ruler of the academy, several students were actually forced to leave simply for upsetting Jakago's mood. New transfer students are supposed to visit the Student Council's office after entering the school. If they don't, their entire class will be in trouble. Despite Jakago's qualifications however, Saki Sukinasaki claims that Jakago only became president because Sukinasaki made her so. After encountering Kumagawa, Jakago broke down mentally and had to be hospitalized. Because of this, Sukinasaki expresses her desire to make Kumagawa the next Student Council president.
- President: Aki Jakago
- Vice President: Iya Renpei
- Treasurer: Usa Hannyaji
- Secretary: Kae Sakanoue
- General Affairs Manager: Tou Kejukuri
Kumagawa's Student Council
Sukinasaki's plan worked; after defeating Jakago and her council, Kumagawa took her place as Student Council president. Sukinasaki joined the council as its General Affairs Manager.
In the pilot chapter, Suisou Academy is considered Hakoniwa Academy's sister school. Notably, the Suisou Judo Club comes to Hakoniwa to take part in an inter-school competition. Despite their star member Beppu losing the first match to Zenkichi Hitoyoshi, the Suisou Judo Club still manages to rally, and win two matches, though they ultimately lose the competition.
