One day, Sang-Woo, a lazy 20-year-old university student as usual, joined a walking program, a system that allows even ordinary people to learn and utilize skills.
Established a few years ago, the waking program has been promoted by the government, and now, the majority of people accept this system and have finally awakened.
Sang-Woo also joined the program without much thought, and thanks to it, he gained the duplication skill.
People around thought that this duplication skill only deceived the eyes by creating illusions, but after Sang-Woo realized that it was a skill that created real bodies, he decided to become a hunter.
Then, before Sang-Woo, who was riding the wave of success with this skill, Jumper George Lucas appeared. Lucas, upon seeing Sang-Woo's duplication skill, felt a certain potential and interest. Sang-Woo, who also felt a small part of the grand plan that Lucas was outlining, couldn't shake off the sense of unease he felt. Eventually, Sang-Woo, continuing his hunter activities, finally learned Lucas's plan and the true dark secret behind it...
