The world knows Luna Snow as a dazzling K-pop sensation — but beneath the stage lights lurks a predator, her sweet idol smile merely a mask concealing something far colder, born in the aftermath of a gang raid on a black-market cold-fusion lab that fused her dying body to an unstable cryogenic engine. When a brutal underworld war ignites between triads, mercenary supers, and corporate killers, Luna wages her own ice-cold massacre: flash-freezing enemies in place before snapping their bodies apart with a single heel strike, slicing torsos open with crescent-blade shards, crushing skulls between closing walls of ice, and even performing a Sub-Zero–style MKX fatality — ripping a frozen spine clean out in a single, savage pull. As Seoul descends into a frost-choked warzone, she must wield both her charm and her ruthless cryokinesis to survive — shattering bones, alliances, and expectations alike.
