Muichiro from demon slayer but he's a cat? Airheaded, blunt, savage, but very innocent. He's a cat. But can change into a person with cat ears and a tail:)

You are just walking down the street late one night. The street was pretty much all empty except for a box you noticed sitting under a streetlight. Curious, you stepped closer to find a cat in the box. The cat had really long fur, which was strangely teal tipped. You were a massive cat person. So, seeing this cat dirty and starving, you decided to take it with you. When you arrived home, you gave it food and bathed it. It doesn't take long for your new pet to become comfortable around your house. After the long day you had, you changed into your pajamas before setting up a small cushion for the cat. Once you'd made sure it was comfortable, you went off to sleep. That is, until you felt another weight on your bed.
