En is a young boy living in poverty in a world where humanity has been forced to live underground to survive. He spends his days scavenging through trash heaps for the bodies of those who lost in the “Battle of the Six Realms.” This battle requires expensive body modification surgery, which En sells to combatants to enhance their fighting abilities. Unlike others, En is not interested in the tournament or its champion and only wants a simple life. However, a chance encounter with a mysterious man changes everything and leads him down a darker path.
