The Labyrinth of
Sealed Sins

When an ancient Quirk sealed beneath UA for generations awakens, it rewrites the campus into a shifting labyrinth of memory and power. Students and teachers alike become trapped inside their own worst moments, forced to relive failures they thought they'd buried. Izuku Midoriya (20) and a handful of survivors — including a sharp-eyed, obsessive watcher who's been tracking him from the shadows since their first year — must navigate the collapsing reality while the Quirk feeds on their guilt and fear. The labyrinth weaponizes intimacy: it binds survivors together in impossible nearness, pushing them into corners where secrets spill, confessions escape, and walls break. Alliances fracture under the weight of old secrets. The only way out is to confront the one memory none of them are willing to face. Some truths, once released, cannot be sealed again. In the dark, between traps of the mind, Deku's stalker becomes his most dangerous ally — her fixation sharpens into protection, her obsession into a love that might save or devour him.
