Hane Sakura commutes to school every day, cycling up a steep hill on her bicycle. She gets introduced to the motorcycle club, commanded by the ever-silent Raimu Kawasaki, after meeting motorcycle enthusiast Onsa Amano one morning. Sakura, who is new to motorcycles, has firsthand experience with the challenge of relearning to ride. However, she thinks that by doing so, she would be able to relive her first bicycling experience, which was both terrifying and exhilarating. Sakura works toward acquiring her motorbike license and experiencing the joys and tribulations of riding alongside Baita, the talking motorcycle; Rin Suzunoki, a Suzuki model enthusiast; Hijiri Minowa, a privileged girl who dreams of being a thug; and professional racer Chisame Nakano.
