Sachi, a first-year university student, became interested in skateboarding after watching a video her brother was watching. While skating, she made a mistake and nearly hit a passing woman with her skateboard, injuring her, but the woman caught her skateboard and gracefully stopped it on the spot. This woman's name was Kurisu. The meeting of these two women marks the beginning of a lively and fun girls' skateboarding memorial for female university students...!
