PotEO: Vampire Maid Ending

The Vampire Maid Ending is an Ending in Prisoners of the Elder One. It occurs after picking up the mirror shard without the broom and dustpan while Camelia is in the room.

Erik slices his finger on the glass which causes Camelia, smelling fresh blood, to feast on him, turning him into a female thrall. She puts Erik, now Erina, to work as a junior maid, and while she does end up recovering her free will, she is so used to being a woman that she doesn't want to change back. After accidentally feeding on her sister and managing to escape sometime in the early 2020s, the three vampires open a vampire-themed maid café.
