Dual cultivation isn't a choice; it's a necessity.

After being struck by a truck like most lucky protagonists (or unlucky ones), Vaan found himself transmigrated into the body of an orphan in the world of witches and demons.

However, they didn't always exist.

Demons terrorized the world ever since the Gehenna Realm descended over 300 years ago. but along with them, came mana, giving birth to witches to combat these demons.

Since then, the world of men was dominated by witches, establishing the seven witch kingdoms, which safeguards at the forefront of the demon invasion.

In order to survive in the matriarchal society of the witch kingdoms, Vaan, like all other men who cannot use magic, had to learn how to service the witches to survive.

Nevertheless, it did not come without its own benefits.

Years of research have led the world to the discovery of intimacy between men and women could increase the witches' mana absorption.

But at the same time, men could absorb some of this mana to improve their physique and lifespan.

Thus, since then, an intricate relationship was formed between men and witches in the red-light districts. Love became casual, and dual cultivation is common.

As a prodigy in the art of pleasing women, Vaan lived a smooth two years since his transmigration as an orphan.

However, everything came crashing down in a heartbeat one day when his life was nearly taken, and Lady Eniwse whom he served went berserk.

Even so, that was not the end.

With the awakening of the Witch Hunter System, watch how Vaan takes on the world and becomes the lord of witches.

Hunting witches does not necessarily imply killing witches if you know what I mean ( ͡° ͜ʖ ͡°)

To him, life was already complicated enough without worrying about things like ghosts or reincarnation. But when a reckless act of bravery ends in fire and chaos, he wakes up to something far worse than death—an unfamiliar world governed by an unfathomable system.Marked as an Anomaly, an existence that shouldn't be, he finds himself entangled in forces beyond mortal comprehension. The world he is reborn into runs on the concept of Ka, the essence of life and fate itself. Yet, unlike others, his Ka does not conform—it rebels. The system that governs this world struggles to define him, its very framework warping around his presence.With each step forward, he realizes that his mere existence is enough to tip the scales of destiny. Some will seek to control him. Others will try to erase him. But one truth remains:'In a world where fate reigns supreme, what happens when something stands outside of its design?'
