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. But these minor hindrances are no match for the special ops training that Chio, AKA the legendary assassin Bloody Butterfly, has received from her extensive gaming obsession.

And so begin the wasteful days of these high school girls, each day kicked off with a simple question: Hey, wanna hear something amazing?
