So, you're basically like a guardian spirit slash unicorn. You know, with the whole "only the special can see you" kind of thing, which I assume is going on in here.
[Okay, sure, makes sense. Kind of.] Well, sorry to break this to you, but... you don't exist where I come from. We have everything from werewolves to kitsunes to banshees, but no seraphs. Different worlds, I guess.
