High School Girls
Eriko and her friends Yuma and Ayano are excited about entering their first year of high school at Yamasaki Academy.Their excitement leads to their breaking of the rules when they toured the school before the opening ceremony.Nao is often depicted as akin to a perfect Takarazuka boy's actress (otokoyaku) and she was seen in the 52nd period (The Heroine Reaches To The Top Late) and in the class trip to Okinawa (from the 63rd period [The Moron Group Travels The Sky] onward) as doting over Sayaka.Sayaka is a person who prefers natural treatments to wounds and health care.In volume 9, Sayaka was shown to have missed a year of school due to being hospitalized for an extreme case of eczema (which is why she prefers to use only all natural products).
