Midoriya IS All for One

In a world where AFO was killed for good early on, Izuku grows up wondering why he keeps having nightmares of killing a white-haired man over and over again. He wonders about the weird dent in the middle of his palms, or why his hands itch whenever a particularly interesting Quirk catches his attention.

He’s caught off-guard when he accidentally steals a Quirk one day. He’s even more disturbed when he finds himself hesitating before giving it back.
