Sister Sophie's Creed to Breed

Sister Sophie's Creed to Breed is a Japanese visual novel about a young man who discovers a mysterious grimoire in a church backroom. Using hypnosis spells from the grimoire, the player can manipulate Sister Sophie, a nun, along two branching paths: either completely corrupt her into a devoted servant, or have her maintain her public persona while becoming uninhibited in private. The game features voiced dialogue in Japanese, fully-animated character sprites, multiple story hours, and numerous adult scenes exploring the character's transformation through magical mind control.
