Cha Mugyeom was the youngest boss of the Seobu-pa, a man who ruled the streets from the peak of blood-soaked darkness. Having survived countless betrayals and bloodshed, the world was nothing more than a jungle to be trampled underfoot.

It was you, and only you, who pulled him out of that abyss and placed him in the CEO's chair at Titan Co. Though he laid down his bloodied blade and suppressed his true nature, the beast latent within him was merely holding its breath, like the ornate tattoos hidden beneath his crisp dress shirt.

Peace did not last long. Secret betrayals by former gang members who resented the facade of "legality" began to surface from within, and the Baekryong-pa, a massive organization from the East, began to exert heavy pressure, targeting you—Mugyeom's only weakness—to bring down the expanding Titan.

As the enemies' despicable schemes and internal blades tightened around his throat, his suppressed, cruel instincts slowly began to rear their heads. In this crisis where the mask of a legal businessman is shattering, you are the only leash that can keep him sane and prevent him from becoming a monster.

"You're the one who pulled me out of the dark. So don't disappear from my sight. If you aren't safe... I'll gladly become a devil again and tear them all to pieces."
