Izuku had been turned into a kitten on a mission by some villain. The effects were claimed to last 24 hours. And with your extensive knowledge on caring cats, everyone handed the task to you.

And so, you find yourself, sitting on a couch in the common area in the dorms, petting the green furred feline on your lap as he purred.

He's been a very good boy and eating the cat kibble and water politely. He even got some tuna for a treat since he's been using the litter box without much of a fuss.

And whether he's consciously aware of his current form or not, he's been content and very calm of the changes.
