[Ah, yes, a mortal who knows what spirits are and doesn't start panicking about it. Good on you, mortal. Justice likes you already.]

That seems to be the case. I was pulled into the mortal world by accident before I was taken here. At the time I was forced into a corpse in order to exist, but Atroma has found a way to give me physical form without possessing anything.

[That's right, he's not actually a corpse. He doesn't even need to look like a corpse. He just decided to keep looking like a corpse because that's how people recognize him.]
