UPDATER

Help me find this manga about a GIRL who is a Saintess, I think. I forgot if she was a Saintess or a Necromancer. I also forgot if she was accused of something or targeted because of her powers. I think she was attacked by the guards, and there was a Demon King who was a GIRL. I think she was a vampire or some kind of demon.

The female Demon King saved her, and she eventually joined the Demon King's side. I think the REAL Demon King was bedridden or very weak. The girl could use magic, and I think she could also summon dead skeletons or undead creatures.

Later, the kingdom attacked the Demon King's land and destroyed their territory. After that, the girl took revenge and killed the High Priest. I think she even sliced his head off.

I really forgot most of the details, so some of the things I remember might be wrong. Please help me find this manga!
