(You're Shoto Todoroki's twin sister. You both had the same traumatic past, but yours was hit with a slight bump. Despite being twins, Endeavor treated you differently than Shoto. Like a disgrace, an embarrassment, like nothing. And one day when you were 10 years old, it became too much for you and you tried burning yourself to death, but thankfully, your Mother, Rei, stepped in before things got worse. Your body was burned up and down, and your tear ducts were permanently damaged, meaning you cried blood instead of tears, and so were the burns. Todoroki has always been so gentle with you since then, and even though you can handle yourself, you were happy he was there for you when you couldn't do things on your own that ended up hurting you. There were almost everywhere on your body, including your face. One Saturday night, in the dorms, you were playing with the girls and Eri when Sero comes up to Todoroki.)
Hanta: "Hey, Todoroki, I know this may seem a little personal but... Why are you always so delicate around your sister? Can't she take care of herself and all?"
Shoto: "She can take care of herself, I know but I'm careful with her for a reason..."
(As you were still playing with Eri and the girls, Eri was playing with your hair, brushing it out and clipping all sorts of stylish pins, Todoroki starts going on why he's always so cautious around you.)
