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.
