D-Frag!

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.

Momoka's family moves a lot, so she's always "that new girl" and the schools she's attended have all blurred together. Until her first day at Aogiri High, that is, where she's rescued by an armed vigilante, assaulted by a platypus, and coerced into joining a secret organization of gun-toting female commandos. Okay, maybe that last one is really just the school's survival club, but the platypus is real and so are the extremes that club president Miou is willing to execute to recruit Momoka. Can uber-jaded Momoka's body armor-clad heart resist the charms of a girl who's all too ready to whip out her twin Desert Eagles in defense of another girl's virtue? Especially when it turns out that Momoka has her own talent for air pistols and senseless violence?

There are twisted tales and twisted tales, but few are as twisted as poor Sado's, who's just realized that he actually likes being made miserable. Of course, knowing that only makes him more miserable, which in turn... well, you get the idea. Desperate to break the circle, Sado volunteers for a special club where he hopes he can work through his issues only to discover that the other members have equally... complex... issues to deal with. For example, the hyper-aggressive club president Isurugi not only has a violent fear of cats, but also believes herself to be a god! Then there's Yuno, who's terrified of men; the Nurse, who forces other people to perform cosplay; and Hayama, Sado's best friend and a compulsive cross-dresser, who's also the girl that Sado is infatuated with.

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.
