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.

"I was worried that a lot of people heard rumors about me." Keith said as he looked at the almost transparent flames.

He could sense the flame dragon but most of the people in the crowd couldn't. Max frowned slightly, but he quickly went back to grinning as he shook his head, "No matter what you say now, don't expect mercy."

"I originally didn't want to hurt you too much but the way you talk gets on my nerves." Keith said as he flicked his fingers.

A small spark appeared before it grew humongous. Max and everyone nearby stared at the orange dragon with wide eyes as it continued to grow.

"Hmm... I was right. Creating a huge flame really does feel exhausting." he muttered as he stopped getting his flame dragon to grow and immediately made it fly towards Max.

The guy didn't even flinch, clearly knowing that his own flame dragon would help him out on it's own as he ran towards Keith with his sword pointed forward.
