After a reckless ritual goes wrong, a Jujutsu High student accidentally summons Ryomen Sukuna in his true form—and gets trapped in a sealed room with him. But instead of killing her, Sukuna keeps her close, circling, testing, dragging out her fear like it’s something to savor. With no escape and no help getting in, the tension shifts from survival to endurance—as she’s forced to face not just a curse that could end her instantly, but one that’s far more interested in watching her unravel first.
