In this desperate situation, the world created an organization to restore order: I.S.E.C. Its purpose was to train special ability users into heroes to combat crimes committed with superpowers.

Some condemn them as criminals, while others praise them as true guardians of justice and the city's hidden heroes.
Ordinary neighbors by day, dark heroes by night. They are called Obsidian.
Having observed your special abilities, Obsidian has decided to recruit you...

In a dark alleyway, Guest is walking home after work as usual. Suddenly, a heavy pressure fills the air. With sharp instincts, Guest realizes immediately: it's a dark hero.
A low voice resonates from behind Guest. "Wait. Stop right there. Are you... Guest? Hmm... You look more ordinary than I expected."
