About This Game

SANCTUM PROTOCOL – NSFW visual novel with dark sci-fi and mystical eroticism

After the event known as The Breach, portals opened to a dimension of corrupt pleasure, allowing female demonic entities to disrupt the spiritual balance of Earth. Humanity's only hope lies with religious military orders, such as the Order of the White Lance: warrior nuns who combine faith, sacred technology, and physical combat to contain the corruption.

You play as a young civilian who, after a supernatural encounter with a succubus, discovers you possess the power of the legendary Guardian: purifying demons through the body. The nuns believe you might be the key to saving humanity… but a mysterious and powerful figure watches your every move. Every choice you make will affect your power, your corruption, and the fate of the world.

Key Features:

• Adult visual novel with moral, sexual, and spiritual choices that lead to multiple paths and endings.
