Endeavor with a quirkless child

This is a 1 part story!!

WARNING: Mentions of child negligence, panic attacks, mentions of abuse.

You are Shoto's twin sister and youngest of the Todoroki siblings, your birth was a surprise for the whole family since the doctors only noticed one baby during the whole pregnancy and Rei didn't even look like she was carrying twins.

You have your father's hair and eye color while the rest came from your mother, being a carbon copy of her with the same facial features and eye shape, it was like seeing Rei with a red wig and contacts.

 When Shoto's quirk manifested but yours didn't Enji waited for a while, but eventually he suspected his daughter was quirkless when there was no change, he took you to the doctor anyway, to confirm his suspicion.

His guess had been right, you were indeed quirkless, after the doctor gave the diagnosis his whole attitude had changed, he barely paid you attention on the way home, but the moment you came back home it was like you didn't even exist, he wouldn't even look at you.

 His treatment caused a huge rift between you and your twin, Shoto wished your father would ignore him as he did to you, you wished he would at least remember your name. your other siblings -especially Touya- and your mother made sure to show you as much affection as possible, with Rei it was a bit harder though, she loved you but the sight of your hair and eye color would make her uneasy, then everything started going downhill.

 Her mental health had been greatly affected by your father's constant abuse, this proved to be fatal the day she accidentally hurt Shoto, your father didn't hesitate when he sent her away. Then the day Touya died the rift got worse. Fuyumi ended up having to step in and take care of Shoto, who you barely talked or interacted, your father made sure you wouldn't go anywhere near his "masterpiece" and distract him from his training, Natsuo took over Touya's place and helped take care of you, trying to spend as much time with you as possible, out of all your family you ended up taking after him the most.

Eventually you ended up spending less time with Natsuo and Fuyumi, Natsuo was busy in high school and with after school activities, sometimes he wouldn't even sleep home, staying over his at his friend's house during a study session. Meanwhile, Fuyumi started college, she was always busy with her studies and with chores, sometimes you'd try helping her when it was obvious how stressed out she was. Being home alone with people that treated you like a ghost was hard. By the time Shoto and you were about to start high school, there was no difference in your relationship, the two of you barely knew each other, let alone talk.

Neither Shoto or your Dad realized you were also going to attend class in U.A., you had done everything yourself and convinced Fuyumi of helping you when it came to signing important stuff.

 A few days before school started you made the decision to dye your hair -sporting a pixie cut- a different color in order to avoid being recognized as a Todoroki, being in the Support department meant you'd probably end up interacting with your brother's class, and the last thing you wanted was to get his attention.

It was during the sports festival people found out you were Endeavor's child. apart from your classmates and the school staff nobody else in school was aware you were a Todoroki. Personally, you blamed Present Mic, he had been so excited during the obstacles race and accidentally yelled out your full name, (Name) Todoroki. You could feel your heart rate dropping significantly, your secret was out.

 "EEEEEHHHH?!?!?!?!"

 The whole stadium was in chaos, everyone was yelling, you could hear some of Shoto's classmates screaming "that's your sister?!" Your brother was speechless, Fuyumi and Natsuo knew this would happen, the whole school was shocked. For the first time in years your Father had noticed you...and he was furious.
