At first I was like, eh, another isekai, but I really liked the twist at the end of the 1st/beginning of the 2nd episode, and I like how you're building the relationship between the MC and Fae
The only thing I'm not feeling is the impact the names are supposed to have. I feel I'm supposed to be impressed by her name being Lucifer, or Lucy Fern, but for some reason I'm not getting it. It's a secondary thing though, doesn't make me dislike the story.
