On her way to her first day of school, Hane Sakura takes interest in her classmate, Onsa Amano, after seeing her ride a motorbike to school. The two go to the school's Bike Club, whose only club member is a silent girl in a helmet named Raimu Kawasaki, who takes Hane for a ride on her Kawasaki ZX-12R. After joining the club alongside Onsa, Hane applies for a motorcycle license, initially struggle with lifting a bike but managing to pull it off after seemingly hearing a voice coming from her bike. During her lessons, Hane comes across another classmate, Rin Suzunoki, who takes her and the others to a bike shop to pick out a bike, only to argue with Onsa when she disses her taste in Suzuki bikes.

As Rin manages to get her bike license, she remains angry at Onsa over her prejudice towards her Katana, but is awed by Hane's honest compliments. Later, a freshman named Hijiri Minowa comes to join the bike club, giving Hane the idea to have Onsa and Rin settle their dispute with a chicken race. Though Onsa and Rin stop in order to keep their bikes safe, Hijiri and her butler Hayakawa go full force against Raimu. On the day of her license exam, Hane becomes nervous when she has to ride a different bike than from her lessons, but Hijiri and the others manage to cheer her on, allowing her to successfully pass her exam.
