Of Cats and Demons (neko!reader x Ciel)
When the thirteen years old neko (name) murders yet another person for her own protection, Sebastian awaits her in the entrance of the ally in which she just killed a man. After a bit of arguing, the girl only knows two things: That butler isn't human, and she is now a maid in the Phantomhive Manor.
