Fallen Priestess: My Sister's Demonic Bloodline v1.30.0 Steam (English, Japanese, Chinese)

Most games about saving family members from dark forces give you a sword and some hope, but Fallen Priestess: My Sister’s Demonic Bloodline forces you to navigate a much messier reality where good intentions collide with corrupted powers. The whole premise hits different when you realize that protecting someone might require embracing the very darkness you’re fighting against.

When Family Protection Gets Morally Complicated

The peaceful life of a brother and sister is upended when demonic blood begins to awaken in the younger sister. To save her from the dark fate that awaits, the elder brother must venture into a world of demons, corruption, and forbidden powers. Will he be able to protect his sister, or will he lose her to the darkness?​
