Hoshino Rei is a girl who in middle school has been overweight and the subject of ridicule. Encountering a handsome high school student from Jion Academy named Akai Sui, Rei underwent a rigorous dieting and exercise regimen to slim down. Upon entering the same high school, Rei at first tries to hide her fujoshi side from Akai, but Akai is too oblivious to know what that is.
Hoshino is a big fan of various works, but is especially fond of the Gundam franchise. She has a couple of close friends, namely her male childhood friend Kamiyu Shoutarou and a comrade in fujoshi activities whom Hoshino refers to as her “Elder in Life.” Her rival in romance, Kurotsuki Luna, tries to use her identity as a fujoshi against her, but ends up only bringing Hoshino and Akai together.
Like her namesake, Hoshino Rei manifests her fujoshi side in the form of a small furry green creature. She approaches history class by thinking of famous figures in “seme” and “uke” categories.
