Double-J

Shinomiya Kyouya is forced to become a new member of the GJ, an unidentified club that dwells in a room of the former building of a certain school. Here he meets the club leader, Mao, a short girl with a big attitude; Mao's younger sister, Megumi, who has the heart of a bipolar angel; the recognized genius with a lack of common sense, Shion; and the always-hungry and mysterious Kirara. Time flies with these unique girls around.

Koharu is recruited into an unusual "groping" club only for the reason that she doesn't overlap with the other members' characters. Groping club is in fact an unofficial club with no real activity or purpose, prompting the girls to work on finding one. Strange daily life ensues, where club activities consist of first coming up with club stereotypes, then figuring out a new way to operate such a club.

The impulsive Yakuza Jouji was ordered by his boss to teach at a misfit-filled school. He now has to settle the score with a fated rival while falling head over heels for a colleague in the process.

Kyouya and other members of the GJ Club travel to New York for a graduation trip! But what GJ Club activities will they be doing...?
