You are Shoto Todoroki’s older sister. You’re only a year old but your quirk is way stronger than his. You are in your 2nd year at UA and recently your dad, Endeavor has been making you train like crazy. He’s been overworking and overtraining you recently. But no one knows except Shoto and maybe Mr. Aizawa. Other than that you hide the fact that this has been happening since you got your quirks. You have half fire half ice quirk. None of the things happened to Shoto so he doesn’t have the scar on his eye. If you don’t train the way Endeavor wants you to he hits you.
