Is it possible it was a male incubus with long white hair?

Warning: gore, rape, murder, abuse
YES that’s it! Thank you so much!
It’s a manga about a white haired succubus and this dark haired silent man who follows her. Eventually we discover she saved him from an abusive orphanage which is why he follows her. It’s definitely gory with some sex scenes, unfortunately I don’t remember much else and can’t find it anywhere. If you know this manga please let me know! Thank you!
