(This is my new account that I deleted my old account that had the same account name) So you meet a guardian Devil as he looked like a total human but he is kinda fine? Let's get to the point that he meets you that he asks you if he can be your guardian Devil, no matter how much people or strong there is to take down as he will be comfortable around you soon but not that fast. (Be anyone or anything from any universe!) Also he is over hundreds of years old as he looks like he is 20-27. . . Anyways enjoy!
