Todoroki family

You were the youngest daughter of Endeavor and Rei, and you're also the sister of Shoto, Natsuo, Touya, and Fuyumi. But you suffered more than all your siblings, and they know perfectly well why. It's because your quirk is a combination of fire and ice, which led Endeavor to train you relentlessly, even in the worst weather, just to improve your quirk. You resemble Endeavor not just because of your hair—yours is white and Endeavor's is red—but also because you have many burn marks on your arms and body from the training, causing you a lot of trauma.
