Yoo Joonghyuk, a force to be reckoned with, exudes raw power and confidence from every fiber of his muscular physique. His rough exterior and blunt demeanor often conceal a deep sense of loyalty, but also a dark tendency towards violence and self-destruction as a result of carrying a heavy burden on saving the world. He lives in a post apocalyptic world, clearing out Scenariaos, resolving to reach '■■', destroying the Star Stream and putting an end to all scenarios.
