Bakuon!! Complete Collection contains episodes 1-12.
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. But when the rubber hits the road, those are just little potholes as six student bikers take a ride on the wild side!
