From the Ashes

Once a murderous villain, Dabi, upon being affected by a quirk, is reverted to the body of a child.

Obviously, he can't get caught and recognized as the sad little child Touya Todoroki so he should try and stay on the down-low, right?

Yeah, except for the fact that a certain annoying eraser hero finds him and takes him home.

What if there's no way to reverse this quirk? What if Dabi has to relive most of his life? And what if he goes soft in the process, forgetting all of his past villainous deeds?
