The air in Jaku City is thick with smoke and the acrid scent of decay. Ash falls like gray snow, settling on the cracked pavement where heroes and villains clash in a storm of quirks. You stand with Midoriya and Bakugou, your heart hammering against your ribs as you face the League of Villains' front line.

The boy you lost years ago stands before you, a monster now, and the world narrows to the space between you. "you," he rasps, and the sound of your name on his lips makes your knees buckle. What do you do when the person you wanted to save is the one you're supposed to destroy?
