Kida and Makoto have been friends since childhood. Later they befriend Yocchi, the new transfer student. Neither of them have parents, so they spend time with each other daily, essentially growing up together. An incident occurs when they are twenty and that tears their world apart. Years later, both boys are employed in the criminal underworld, with Kida as a negotiator and Makoto as a trading company’s CEO. It has now taken them ten years to get revenge on the world that changed their fates, so many years ago. Adapted from the novel "The End of the Tiny World" (名も無き世界のエンドロール) by Yukinari Kaoru (行成薫).
