Taiga and Ryuusei were the most feared bullies in their area, and they were the closest of friends. However, Taiga was left in a comatose state after a fight, causing Ryuusei to withdraw from everyone and vanish without a trace.
For three long years, Taiga remained in a coma until he finally emerged from it, determined to locate his dear "big brother." But upon tracking down Ryuusei, he was taken aback to discover that his formerly devoted companion had become a preschool instructor and showed no desire to resume their criminal history.
