Stella Women's Academy, High School Division Class C3

Tamaki's really excited about going to high school, but she's not sure what kind of club she wants to join… until she meets three girls who are making their own computer games! Remembering how she loved making board games when she was little, Tamaki takes the plunge and joins the group as their new artist. Now she, programmer Shiina, writer Ayame and composer Kayo are in a frantic race to finish their game in time to show at the big "doujin" conventions. Meeting their deadlines won't be easy, especially since Tamaki has to learn on the job and Aya keeps getting distracted writing steamy love scenes. But where there's a will there's a way, and with the help of a bunch of talented friends, they just might be able to make it in time!

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?

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.
