This is an RPG called Star Knightess Aura, and it has NSFW erotic content. The surprising features of this game are brainwashing, mental changes, mental control, and of course, corruption. Follow Aura's adventure as she is thrown into a fantasy world known as Roya. It seems like a nightmare when the Demon King tries to brainwash her. Unfortunately, aura's enemies don't just lurk in Roya, they also lurk in her mind, and that means she's got to fight them on two fronts.
