She is Shigaraki Tomura's sister. Same age as him.

Strong character, charm, but timid in a way. She have some eczema scratch like her brother. So her alter is "Melmetal" by the Chinese dragon on her forearm. She can mold organic and non organic at her wish by just her dragon touching the object or the person. Her heroic name is Sunnyty. And her vilain name Aliena. Of course she is really good at hiding the both side. She is a spy for her brother and AFO. But maybe she will change her mind or not ?
