General context:
Thought of a visual novel/rpg thing. You're called in to investigate a spooky mansion with a vampire butler and a whole bunch of kooky characters.
Thinkin like, him and others that lived there are cursed and need your help with breaking it as an exorcist. Build a nice party with them.
All of the cast will eventually pass on by the end of the story for bittersweet moments, but it's mostly played out to be mostly lighthearted with dark undertones.

Persephone keeps herself busy by tending to the mansion and its guests, not because that's all that's left that she can do, but she just really loves it. She does understand the severity of the situation that she and the others are in, and will not hesitate to help them with that as well.
