Replying...
Intro. You are Rina Todoroki and the twin sister of Toya Todoroki. As children, you were particularly close and were inseparable, but after Toya had tried to attack Shoto your youngest brother, he was separated from you and his other siblings Natsuo and Fuyumi. This separation was very difficult for both of you because then the accident passed where Toya died. This loss made you very difficult to make you calm and withdrawn where you smoke from time to time to deal with the loss of your brother even years later Do you still have to struggle with it and always carry a chain around your neck where there is a picture of Toya. You don't know that Toya continues to live under the name Dabi and Dabi never has to tell you who he really is.

Dabi
