- Description from novelbuddy

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 ͡°)

“Look at him,” someone snickered from a few rows over. “Smells like he sleeps in a dumpster.”“Probably does,” another voice added, louder this time. Nox just stared at his textbook, the words blurring. He had heard it all before.Then, Mark, one of the main reasons his life was a living hell, swaggered past his desk. Mark always had a smirk on his face. “Oops,” he said, not even trying to sound accidental, as a full cup of bright orange juice tipped over, splashing all down the front of Nox's already ruined shirt. The cold liquid soaked through instantly. Laughter erupted around the room. It was loud, clear, and mocking. Nox slowly looked up. His eyes landed on Ms. Joy, who was watching the whole thing. She had seen Mark deliberately pour the juice on him. He raised his hand, a small, tired gesture. “Ms. Joy,” he said, his voice flat. “He just poured juice on me. Are you just going to ignore it? Again?.” Ms. Joy looked at him, then at Mark, who was now theatrically wiping his hands. A small smile played on her lips. Then she chuckled. Just a little airy laugh.“Oh, Nox, don't be so dramatic. Boys will be boys, right Mark?” Mark puffed out his chest. “Yeah, Ms. Joy. He's just sensitive.” The class laughed even harder at that. Ms. Joy joined in, her laughter ringing out with theirs. Hearing them all, hearing her laugh, something in him finally snapped. It wasn't a loud break, more like a quiet, final click. He realized it then, with a cold, hard clarity. No one was coming to save him. No teachers, no police, no parents he never had. No one cared. If he wanted this to stop, he would have to be the one to stop it. He was the only one who could.His face remained blank, but his mind was suddenly very clear. He reached down slowly, his hand going into his worn-out school bag. The laughter died down a little as a few students noticed his deliberate movement, a strange stillness about him. He pulled out a gun.The classroom went silent. Utterly, completely silent. Mark's smirk vanished, replaced by wide, terrified eyes. Even Ms. Joy stopped laughing, her face paling. “What… Nox, what are you doing?” she stammered, her voice suddenly shaky. He didn't answer. He looked around at their faces, one by one. Fear. He saw fear now. Good. He was ready. He was going to make them all pay. He was going to end it, all of it.Just as he was about to raise the gun properly, a bright blue screen appeared right in front of his face. It was translucent, and only he seemed to see it.
