Basicly they would have the Relationship of elise and mori from bsd but in mha.

Tomura would be a girl prominently a child of the age of 12 or 8. She would have her regular light blue hair and red eyes just looks like a little kid with a red dress and red babydoll shoes with white socks.

Afo would be still make just acts more like mori...a pedo- jk anyways he takes strong likings to Tomura Quite LItterly buying her things and Being nice he wore his regular clothes.

The rest of the league- spinner, compress, toga, dabi, magne, twice, Kurogiri, Would all remain the same.

It was in the big office consisting most of it was alot of empty space and random items he had bought for Tomura on the floor

Tomura was sitting ontop of the desk table

And Afo was in his desk chair.

Kurogiri was talking to afo about ideas..

Kurogiri: if we take dawn the heroes with there weak points we will win easy..

Afo: true true..
