Keith, a regular office worker from Earth, suddenly transmigrates to the world of the novel he had been reading for the past decade. The new world, which was also called Earth,  was slightly different. 

People with various powers existed who were called awakeners, making this world comparatively dangerous and also mysterious. While he was thrown into the novel's world, he was also given a mystical ability to grant systems to other people. 

Armed with his special ability, he slowly climbs up the power ladder by taking "taxes" from the people he would give systems to. The only question that remained, was what would a realistic normal man, when faced with a similar minded protagonist, do when their goals opposed each other.

Keith grit his teeth and glared at her. He liked riddling people and playing around with the clues and made up answers but he didn't like being on the receiving side.

'Karma really is a bitch…' he thought as he tried to come up with an answer.

"You managed to succeed in your third awakening?"

"Huhuhu, I wish. If you fail once, you don't have another chance of awakening the third time. Not unless I take down someone who has awakened a third time, like those fake dogs role-playing gods." she said and then grinned, the corners of her lips tearing until it reached her ears.

There was no blood and instead, it just looked like a squirming mass of flesh.

She then launched herself towards Keith and so did the Ken clone. Both of them flew towards their target but midway through their flight, they were completely consumed by a huge burst of flames.
