The Witch Hunter System

Dual cultivation is survival, not indulgence.

A truck collision thrust Vaan into an orphan's body within a realm of witches and demons—a world that wasn't always this way. Three centuries past, the Gehenna Realm descended, unleashing demons upon civilization while simultaneously birthing mana and the witches who would stand against them. Seven witch kingdoms rose to power, their dominion absolute, their defense paramount against the endless demon tide.

In this matriarchal order, men without magical gifts face a singular path: service. Vaan mastered the art of pleasure, trading intimacy for survival—a practice rooted in discovery. Research unveiled that physical union between men and witches amplified mana absorption, while men gained strength and extended years from the exchange. Red-light districts became places of transactional intimacy, where dual cultivation transformed need into system.

Two years passed in relative peace for Vaan, a prodigy in his craft. Then catastrophe struck. A near-fatal attack shattered his existence, and Lady Eniwse, his patroness, descended into madness.

From the ashes of ruin, the Witch Hunter System awakened within him.

Now, Vaan rises to reclaim his destiny and dominate the witch kingdoms themselves.
