What would you name a Cheshire Cat like Charector? Japanese name?

I drew this version of the cheshire cat charector. He's a man with cat ears and a tail. He is a phyco path killer with and ax and he is the king of his world. He has anger issues and again, a phyco path. He has a gravity defying top hat and he is dressed in all black and pink with a tail coat. His cane is an ax. I would really like if his name had a Japanese origin. I'm looking but google isn't helping much :( thanks in advance :3
