Piercings: She has six earing piercings in both ears. Three in the ear lobe, and three along side the side of her ears. On her (for her POV) left ear she also has an industrial bar. 

She also has a nose piercing, again, for her POV, on the left side. 

Tattoos: A small cross behind her right ear, and a small Ying and Yang one behind her right ear. She also has the women/venom tattoo on her right pinkie, and some basic decorative tattoos spread over her body, in more hidden places as her back and inner thighs.

(A/n: I know that tattoos aren't really appriciated in Japan, as they are associated with criminals, and she does deal with this. She wants to teach people that tattoos are just like art, but then permantly on a body, and nothing to be associated with to criminals)

Story:

She was born as the eldest of the Todoroki family, and cared deeply for her siblings. She was trained by her father, but gathered a lot of hate for him as he was abusive, and stood up against him. He discarted her, and went on to have other children he hoped would be succesful. 

She always took the blame for her siblings, as she wanted to protect them. She suceeded, except with Shoto. She did always comfort him, and was like a second mom. All of the siblings listened to her, except she had a bit of trouble with Touya and Natsu. 

When she was fifteen, her father wanted her to join UA, as she did have the talent to become a great hero, and Shoto was struggeling with his training, and Touya couldn't make it big due to his complications. She refused, and tried to convince her siblings to come with her to live with their grandparents on their mother's side. 

Touya snitched however, and she got into a big argument with her father, and then left alone. She took her mother's name, as she did not want to be associated with her father, and secretly kept contact with her siblings, even Touya. She started to live with her grandparents, and attended Shiketsu high school, as she did desire to become a hero. 

She made great friends, and went to therapy to deal with her trauma. She vistsed her mother frequently, and tried to visit her siblings when her father wasn't there. 

When Touya died, she felt incredible guilt, as she felt that she had failed as a big sister. She was supposed to take care of him, and now he was dead, while she didn't even live with them anymore. Her siblings convinced her not to come back, as they said 'You're free from dad, do not come here for us. We promise we'll make it.' 

She gratuated top of her class, and she signed to be a sidekick of Ryukyu. After three years she became a hero, and a year after a pro-hero. She kept her identity secret though. Only her siblings and mother knew.
