六道闘争紀

人類が生き残るために地下に逃げた世界で、エンは自分より恵まれた人々のゴミを糧にして生きている貧しい少年です。In a world where humanity escaped underground to survive, En is an impoverished boy who lives off the trash of those more privileged than him. He spends his days in the slums, looking through a trash heap for the decomposing bodies of losers, those who were defeated and killed in the Battle of the Six Realms. To participate combatants have to undergo an expensive body modification surgery, and En sells these modifications, machines attached to their bodies that significantly increase fighting ability. Uninterested in the tournament and its champion, unlike everyone else, he aims only for a worry-free life. But one day, a chance encounter with a mysterious man shatters his reality and puts him on a different, more gruesome path.
