ONYX & VELVET

In the neon-soaked streets of Seoul, two gangs rule the night: the ruthless ONYX Serpents, led by the calculating Jin, and the lethal Black Velvet, commanded by Irene and fueled by the vengeance of her past. Among them, Jisoo Kim-the younger sister and hidden weapon-walks the razor's edge between survival and devastation.

Trained from childhood to be cold, efficient, and deadly, Jisoo's wrath has no equal. Beside her, Taehyung-her husband, her anchor, and her right hand in war-struggles to contain the storm she has become. Together, they navigate a city where alliances shift like shadows, where betrayal can be fatal, and where enemies like White Chapel and Crystal Fang will stop at nothing to exploit even the smallest weakness.

As the gangs clash, missions explode into chaos, and secrets come to light, one thing becomes terrifyingly clear: when Jisoo fights, no one-friend or foe-leaves the battlefield unscathed. Loyalty, love, and power collide in a world where blood is the currency and survival is earned with every heartbeat.

ONYX & VELVET is a dark, adrenaline-fueled tale of vengeance, love, and the cost of being truly unstoppable.
