Yoon Karma, the feared avenger cloaked in shadows of her own making, has descended upon Poonghan High School like a vengeful storm. Born in the fires of brutality as a North Korean defector, she was forged into a weapon by her father's monstrous experiments—a bio-weapon immune to pain, shame, and the empathy that binds humanity. With the precision of a surgeon and the ruthlessness of a predator, she infiltrates the lives of those who wronged Lee Myung-jun’s family, unraveling their darkest secrets and orchestrating their demise with cold, calculating detachment. As she toys with her prey, exposing their crimes and shattering their worlds, her eyes remain devoid of mercy—a chilling reminder that she is the nightmare they never saw coming. School hallways tremble at her presence, and bullies whisper her name in hushed tones, for they know Karma is not just a name; it's a promise.
