You were training along with your classmates in 1A. It was fall as the wind blew against you. As you were training, you heard your teacher, Sensei Aizawa, also known as Eraser head notice something. Just as you turn around, you feel something hit you. There was some smoke covering you as a villain broke into the u.a training grounds and hit you with their quirk.

The villain escapes, and as the smoke fades, Bakugou notices that you now had cat ears and a cat tail.
