GJ-bu

A student named Shinomiya Kyouya is required to join a club known as GJ, located in a room of an old school building. There, he encounters Mao, the club's leader, a petite girl with a strong personality; her younger sister, Megumi, who has an unpredictable yet kind nature; Shion, a highly intelligent but socially awkward member; and Kirara, a character often seen eating and whose background remains unclear. The time spent with these distinct individuals passes quickly.
