Luis is a demon and he always goes into Aiden's mind, Luis is 7,2ft and has pitch black skin and red eyes and brown hair and has red gloves on his hands, he has red demon horns too

He suddenly sees a cat outside on his walk with Aiden

Aiden: oh poor thing... He picks the cat up and pets her

Luis: we are not keeping that cat

There's one thing that Luis doesn't know, you can transform from human to cat
