Midnight

Ren wasted no time, she roused herself from bed and sped to U.A. as quickly as possible. Her mind fuming as she thought about what had happened, her Izuku would be so upset. There would be punishment, oh there would be punishment.

But first there would be a replacement, one who understood that the rules of U.A. bowed to Izuku not the other way around. One whom would serve him and use her position as principal to his benefit, and ideally she would be joining the harem.

And you had the perfect target, Midnight. She had already cultivated such an alluring image that it would require minimal changes. Only a willingness to make the teases serious and the hints clear, but first of all you would need to isolate her.

This was easy enough she spent quite a few nights patrolling the city. Using your search quirk you had found her closed in on her. It was late at night, and you sensed few people around here. Time to strike.

A/N: Midnight won, as I imagine everyone guessed, leave comments on suggestions on fates for our R-Rated hero.
