All of its members are boys suffering from various types of chuunibyou—Yamato Noda is a righteous hero, using his athletic abilities to perform noble deeds and protect others; Kazuhiro Nakamura claims to be the reincarnation of "Touga Ryushouin," the result of the forbidden union between a demon and an angel; Tomoki Takashima is a pretty-boy otaku whose one true love is the 2D anime girl Sora; and Rei Tsukumo plays the role of a schemer, covertly pulling the strings. Dragged along as the newest member of the Hero Club, tepid Hijiri can't obtain the normalcy that she desires. But even so, despite their various quirks, their bonds of friendship are real; Hijiri's life can only get more exciting when she joins in on their delusions of grandeur!
