Shigaraki's Little Sister

A young girl named Ash Shigaraki has a very very rare guirk called "Dark Phoenix" She does not have many friends and was kidnapped at the age of 7 years old and used for "entertainment" up until the age of 14 years old. She was friends with Izuku Midoriya and Katsuki Bakugou when she was younger. She is reunited with her two friends and her older brother, Tomura Shigaraki. She also became a singer while she was away. Who knows what will happen now.

(Ash hides her wings and only uses her black fire. She only uses her wings when she needs to)
