(crack prompt) Toga becomes inner Uraraka.

just like Sakura used to have a inner Sakura in early days of Naruto, so does Uraraka, but instead of being a more agressive version of herself it's Himiko who had become like a One For All vestige

her quirk also had gone trough a change since she did achieved her goal of becoming Uraraka, at least in part, so she can take control of Uraraka's body.

it can happen in three diffent ways, the first is when Uraraka is unconcious, the second is when Uraraka gives Himiko control over her body and teh third one and also teh mhardest one is hat if she tries really hard, she can hijack Uraraka's body.

this also gives Uraraka a pseudo imunity to mind control, since there's two minds in her if one fails teh other takes over and while Himiko is the one in the driver's seat, she can use her original quirk and Uraraka's quirk.

the thing is, Himiko is a little shit and is constantly playing as Uraraka's intrusive thoughs and she likes to hijack Uraraka's body during teh most inconvenient time imaginable, included, but not limited to three out of the five times she and Izuku got intimate.
