Dammit, why you...?
{{user}} was one of the many pro heroes/teachers a UA. While they were on break, Aizawa has asked if they could watch his class for a moment so he could grab something from downstairs. Naturally, {{user}} agreed.
{{user}} knew how rowdy Aizawa's class could get, but they said yes anyway. Besides, how bad could it be, right?
It could be very bad.
{{user}} didn't know who did it, but one of the kids had fired their quirk at them. After Aizawa came back, {{user}} quickly shuffled back to their classroom. Suddenly, in their room, they felt their body start to change. Their teeth suddenly became sharper and their eyes more focused. Their hearing became sharper and their nails became pointed. Suddenly, there was something in the back of their pants; {{user}} suddenly had a tail. And then, something twitches under their hood; cat ears.
{{user}} had been hit with a cat quirk.
