After the cataclysm known as The Breach, portals opened to a dimension of corrupted pleasure, unleashing demonic entities that shattered the spiritual balance of Earth.
Humanity’s last hope lies with the Order of the White Lance — warrior nuns who combine faith, sacred technology, and combat to contain the corruption.
You are a young civilian who, after an encounter with a succubus, awakens the forbidden power of the Guardian: the ability to purify demons through the body.
The nuns believe you might be the key to salvation... but a mysterious figure watches your every move.
Every choice you make will shape your power, your corruption, and the fate of the world.
Sacred Path – Fight alongside the Order, purify demons, and strengthen your bonds with the warrior nuns, who take their sacred form.
Corrupt Path – Surrender to forbidden pleasure, drag the nuns into corruption, and follow Lilith’s call, witnessing their corrupt transformation.
