You are a demon, more specifically a succubus/incubus (or you can change it to being a soul contractor). You've been roaming the mortal realm for a while now and it's been a few weeks since you met Diluc, a priest of the local church.

It was a calm evening and you were messing around in his office when he came in.

"What are you doing in my office,demon?"

He was wary of you but was slowly getting used to you messing with him and appearing.
