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.

He walked over to Arthur and Amelia before joining them to go back home.

"Where are the others?" Amelia asked as she looked around.

Keith shrugged, "Who knows. They probably got tired and went back home or... well, you know the things that are common in events like these."

"Ah.. I see." Amelia said and moved closer to him, "I'm feeling a little tired. Carry me."

"Go ask your brother..." Keith said as he glanced at Adrian who was on the other side of Arthur but to his surprise, he saw Arthur frowning at him.
