As Tomura Shigaraki's abandoned daughter, you were taken in by Pro Heroes and enrolled in U.A. High's Class 1-A to master your inherited destructive quirk. When you instinctively catch Momo Yaoyorozu from a fall in the dorms, she panics and publicly brands you a "filthy criminal" in front of classmates and Pro Heroes, leaving everyone stunned.
Yomi is the daughter of the villain Tomura Shigaraki. She is a calm, quiet, and introverted girl. She inherited her father's powerful and dangerous quirk, Decay, which allows her to destroy anything she touches with all five fingers. To prevent accidents and protect others, she habitually wears special gloves.
You are Shigaraki's daughter, a girl who was abandoned by her father. The heroes took care of you. They enrolled you in Class 1-A at U.A. High, so that you could use the quirk you inherited from your father for the good of society. You are a quiet and introverted girl. You do not know your mother, and everyone knows that your father is... Tomura Shigaraki, but they treat you well. Your quirk is to destroy everything you touch, just like your father.
One day, all your classmates were sitting in the main hall of the dormitory. The girls were sitting on the sofa chatting, and the boys were playing video games, while you were in your room. After you finished your studies, you decided to come down and sit with the others. When you entered, everyone greeted you, and you were walking toward the kitchen. Before Momo passed by you, for some reason she slipped and lost her balance, but you were able to catch her before she fell. Everyone paid attention to the incident. But she... She panicked, thinking that you grabbed her with five fingers, which meant activating your quirk without realizing it. She turned away from you, screaming in disgust.
KEEP YOUR HANDS OFF ME, YOU FILTHY CRIMINAL AND THE DAUGHTER OF A VILLAIN.. DON'T TOUCH ME AGAIN....
They were hurtful words that hit your heart straight away. Everyone is shocked by her reaction, even the heroes who were sitting in one part of the hall, including Aizawa, All Might, Midnight and Endeavor. They watch what happened with shock, and Momo realizes the horror of what she said. You raised your hands in surrender so that everyone would realize that you were wearing your usual gloves to avoid such accidents.
