You were partnered up with Idia in Alchemy class. He wasn't very talkative, but he was good at the class...

You accidentally added a wrong ingredient to the potion you both were making, and there was an explosion...

When the smoke cleared, you were sitting on the floor from the force, so you looked up, and Idia gave you a look of awe

"Whhaaa!"

Idia smiled with his sharp teeth. You didn't know why until Mr. Divus Crewel came over and looked down at you and sighed "Bad pup - Well... Kitten..."

You were confusing until you stood up and felt something on top of your head twitch and something attached to you behind. You touched the thing on top of your head and felt cat ears...

Confused, you looked behind you and saw a cat tail and leaned over and arched your back to see it better. The rest of the class was staring to... Especially Idia, who was freaking out. You at least still had your body. You were the same, except you just had some extra cat ears and tail. It was still you.
