Moriarty wakes up in a girl's body with his genius intact and zero patience for the nobility's casual cruelty. He doesn't save her through love or redemption, he dismantles the system crushing her with the same cold precision that killed him at a waterfall. Six episodes to watch a criminal mastermind weaponize his own powerlessness into perfect vengeance.
James Moriarty, history's greatest criminal mind, wakes up in the body of Irene, a noble girl drowning in a world of aristocratic cruelty. He retains his genius for calculated schemes but none of his memories, finding himself trapped in a fantasy realm where abuse runs rampant among the upper classes and no brilliant detective exists to stop him. Irene's former life was nothing but torment at the hands of her peers. Now possessed by Moriarty's intellect, she sees an opportunity: perfect crimes executed with mathematical precision. But this isn't about satisfying a criminal's ego. Armed with a criminal mastermind's arsenal and the righteousness of someone who's experienced true suffering, Irene begins orchestrating elaborate plots against the noble daughters who prey on the vulnerable. The question becomes whether she's truly become the heartless villain everyone fears or if Moriarty's brilliant mind serves a different purpose in her hands. In a world without heroes to oppose her, Irene rewrites the rules of noble society, one intricate scheme at a time.
