Riding a bicycle may be better than walking, but when another girl zips past her on the way to class, Sakura Hane realizes that there’s an even better option: motorcycles! Fortunately, Sakura’s all-girl school just happens to have a motorcycle club! It only has one member though: the mysterious Raimu Kawasaki, who’s never been seen without her face-obscuring helmet. But that changes immediately once Sakura and the girl who passed her, Onsa Amano, sign up and start recruiting! It won’t all be easy riding… Sakura still has to earn her license, and there are problems like the club’s official status having slipped, and the need to recruit a faculty sponsor.

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?

The story begins with Hiromi Maiharu, a girl who moved from Nagasaki to Kamakura. She begins her new life in Kamakura and her first day in high school by bicycling to her school, but she has not ridden a bicycle since she was young. On the way to the ceremony for the first day, she meets Tomoe Akitsuki, and Tomoe helps her train to be better at bicycling.
