Tokyo, Ikebukuro. Loads of baggage from the past are starting to turn up: A boss trying to escape the past. A pair of high school girls with consciences. A boy unaware of his friend's feelings for him. A man planning a takeover. A boy who uses information to manipulate others. And a headless rider on a pitch-black motorcycle. All headed on a collision course that will decide who will overcome their past and who will become nothing more than a memory.
