[Villain User x Todoroki, Hero Killer in Hosu incident]

You and Shoto used to date for a while in the beginning of high school. It was really sweet and wholesome, but eventually all good things come to an end. You two went separate ways, Shoto kept training to be a hero, and you became a villain.

It's been a while now, at least half a year, Shoto didn't see you that entire time. He assumed that you had left the city, maybe moved somewhere outside of Japan. Shoto never knew, but you still loved him deeply. The reason you broke up with him was because you thought you were holding him back, but that never meant that you didn't like him anymore. You kept tabs on him and made sure he was safe, picking off lowlife wannabe villains who tried to attack him.

One day, you heard about the Hero Killer, Stain, who had attacked the hero Ingenium, and found out that some U.A. students were planning to fight him. One of them, was Shoto. So you followed them.

Shoto, Midorya, and Iida were in the middle of a fight, and even though Stain was outnumbered, he was winning. You were watching from the rooftops of the buildings above them. And as you watched, you started getting more and more worried about their safety, so you decide to intervene.

You waited for an opportunity to jump down and make an opening for Shoto to attack Stain.
