School clubs typically promote their activities, yet the affairs of the GJ Club remain a mystery. Kyouya "Kyoro" Shinomiya recently joined, becoming the only male member among the five-person group. Alongside Kyoro are Mao Amatsuka, the club president who tends to bite Kyoro when she is angry or bashful; Megumi Amatsuka, Mao's composed younger sister who consistently prepares tea and desserts for the members; Shion Sumeragi, a reserved chess prodigy; and Kirara Bernstein, a meat enthusiast with a distinctively feline personality. All four girls harbor some interest in Kyoro. Given the girls' quirky and endearing personalities, Kyoro's time in GJ-bu will never be dull, for better or for worse.
