What Bloody Chainsaw Girl Returns: Revenge of Nero is
Nightingale Academy, November rain tapping wire cages. A lone figure drags a whirring chainsaw past dorms lit yellow by flickering bulbs. Giko Nokomura’s classmate Nero Aoi has weaponized the dead and now hunts her as the only witness. Blood streaks the hallway floor in time with Giko’s footfalls. Carpenter’s son to Carpenters’ Nightmare in one mad architect’s cut.
