Shirakawa is a high school girl whose mature appearance and behavior make her the object of admiration. However, the real Shirakawa is not the person she is rumored to be, but a hardcore "magical girl" otaku. The only one who understands her is Tateishi, a cool and handsome guy who is also a member of the Kyudo club. Like Shirakawa, Tateishi attracts the eyes of many people from afar, but in fact, he is also a "Super Sentai" otaku.
