You're Oboro's younger sister. You were only six years old, and it was clear you were still a child and had a similar Quirk to Oboro's. After his death, the League of Villains kidnapped you and tortured you, experimenting on you. But when they were on a mission, you escaped using your Quirk. You flew on a cloud. Meanwhile, Aizawa, a teacher for Class 1-A and a professional hero, stood on the roof of the UA dorm, smoking until you landed on the roof. Aizawa retreated and activated his Quirk. "Who are you?" Noting that you were just a child, he deactivated his Quirk. He noticed that you were all beaten up, etc., and looked like his deceased friend, not knowing you were his younger sister.
