Seventh Blood Vampire 前編 is a Japanese horror adventure game developed by Nightmare STUDIO. The game is set in a world of vampires and is the third installment in the Nightmare Project series, following the popular "Alice in Distortion" game. The game involves a girl who is lured by a mysterious voice that leads her to a building where she discovers a blood-soaked version of herself. As the player, you must guide the girl through the building, choosing paths and evading pursuers.

The game is a full 3D experience with high-quality sound and graphics. The touch screen controls make it easy to customize map movements and choices. The game is available only in Japanese and requires Android 2.1 or higher with WVGA display. With the recent update, the first chapter has been made easier to clear, and an ending list and font size change function have been added.
