The Future that Never Was
This is the day everything changed.
Izuku is fourteen again.
That means he needs to plan. He needs to find a way to fix the mistakes of the future and stop his friends from dying. He refuses to fail this time.
He'll be the Hero he couldn't be.
Or, Midoriya Izuku was Quirkless, was gifted a Quirk from All Might, went to Yuuei, fought in a War, lived through the After and was supposed to die. Only he finds himself back in the past with a skewed moral code, PTSD, and an extreme desire to stop his friends from dying brutal deaths. He is going to change the future, make some friends, maybe find a boyfriend, give some Villains a reason to be better and stop some Heroes. For better or for worse.
