Meeting future Eri

You actually didn’t know this much about the little girl Eri, only that she was once a victim that Izuku had rescued. When you had removed Aizawa from the school you’d sent her to live with Mirio, having used your quirk to ensure no one would complain. But you knew that she was nothing like the woman before you.

This new woman had two horns instead of one, looked about eighteen with silver hair, a voluptuous body and and mad look on her face.

“Why are you here?” You ask curiously.

“It’s my birthday.” She replied desperately.

“Do you mean right now? Or that it was your birthday when you came back in time?” You ask, to see a slight bit of confusion on her face.

"The latter I think, I'm eighteen now. I can be Izuku's ****." She said with a gleeful smile, "I've waited so long."

You started to put things together, and began to smile "I see what's going on dear. So shall we visit your younger self?"

She nodded with a delirious smile, "yes plant the seed that will keep me infatuated with Master Izuku. Make me spend puberty dreaming of the day where I can become Izuku's sex ****."

"We'll see." You explain, and she smiled brightly.

A/N: So following Ookami12354’s suggestion the plan is to use Loremaster as the fanart and have Ren use her quirk to make her grow up to be akin to Darkness from Konosuba. Leave your suggestions and thoughts about this path in the reviews
