For the average Japanese high school student, walking to school can be a chore, but for first-year Chio Miyamo, it's always an adventure. Constantly running late due to her long night sessions playing video games, she is forced to come up with new routes to make it to Samejima Private Academy on time. On her many bizarre journeys to school, Chio contends with obstacles like street-blocking detours, overzealous kabaddi players, and befuddled motorcycle gang leaders.

Together with her best friends Manana Nonomura and Yuki Hosokawa, Chio will do whatever it takes to avoid her school's harsh penalties for tardiness. [Written by MAL Rewrite]
