That's quite an interesting start. It's rare you get to see a story where the undead are put to a less destructive use. I do wonder if she's imply animating the body or if she's enslaving the person's soul.
Somehow this remind me with Maou no Ore ga Dorei Elf wo Yome ni Shitanda ga, Dou Medereba Ii?
Anyway followed, this seems like a good read
Thanks for the work
