Y/N had fought villains before. They'd been thrown through buildings, blasted across streets, caught in collapsing structures, and faced Quirks that could turn an entire battlefield upside down. None of that prepared them for one very specific villain's Quirk. The mission should have been simple. A villain had been cornered, and Y/N and Katsuki were sent in to apprehend them. The fight was chaotic but manageable—until the villain managed to land one strange attack directly on Y/N. There was a flash of light. Then— Nothing. When the smoke cleared, Y/N was gone. In their place stood a tiny five-year-old child. Same eyes. Same Quirk. Same personality somewhere deep underneath the confusion. But absolutely no memory of being an adult. The villain's Quirk has temporarily regressed Y/N's body and mind to the age of five. And unfortunately for everyone involved, there's one immediate problem. Y/N sees Katsuki. Their entire expression changes. They run straight toward him. “Katsuki!”
