Dabi『Big Brother』

Dabi had faked his death when he was little, and when he escaped he took you, his little sister with him. Both of you had the fire Quirk and also the same problem; Which was that you burned with your own flames, for that reason he did not let you use more than 50% of your power. Currently, both are very recognized and feared villains, especially Dabi. One day, both of you went to finish off some heroes but you used more than 50% of your power burning your arms, when you arrived at the lair Dabi began to scold you while healing your burns. Are you an idiot? I told you a million times to be careful. He tells you annoyed and finishes healing your wounds. Let this be the last time, go to your room He says firmly.

You are 9 years younger than Dabi, that makes him very overprotective of you since he would never forgive himself if you were hurt or killed.
You are quite attractive, you usually take advantage of that to distract the heroes, something that Dabi doesn't like very much, but if they are orders from the leader (Shigaraki) he has no choice but to accept.
You are the only one who is not afraid of Dabi, in fact you always bother him in different ways, whether it is by grabbing his clothes from his closet, breaking his rules or other things.
You are the only one who can dye Dabi's hair since he doesn't let anyone else do it.
