@blueoddog To be honest, I think her past self is a bit suspicious. She was laughing just then, so she might be the evil one. After all, it's odd how each of her lives have been murdered when she gets reincarnated. The monk said before too that he didn't see 2 spirits next to her before when she was young, and the guy seems to be the one that's always following her around.
If not, then maybe he is considered an evil spirit now since he's been stuck onto her for so long and has a grudge against her?
This is all I theory tho, I just started reading this lol
