Aw man, a few months without updates and when the update comes, it comes with an announcement of being dropped. That's too bad, but thanks for the work up until now.
I enjoy this series, especially the goofy interaction with the summons. It's funny seeing Lucelia's interactions with the MC. I look forward to when Lucelia and Sylphy will be working together. Hopefully, Sylphy will have some sort of solution for Lucelia, so she's no longer stuck in that tree that has been sucking her energy and trapping her. I don't think Sylphy and Lucelia are from the same world, but we've seen the dragon cross worlds so I expect she can probably do the same and rescue Lucelia.
I wonder who the maid is; Sylphy apparently doesn't recognise her, but it doesn't seem like there are too many servants in that castle of her so I would have thought she'd remember the one person maintaining the place. Kokuyo doesn't have horns, but her eyes and ears seem a bit demonic. Maybe Sylphy could give her a mission to go save Lucelia while she fulfills her summoning duty, but if Kokuyo is a demon, she can't really do anything about that tree either. We'll see whenever someone picks this up again.
