Shin Kinghad is a kid that had been abducted and trained by a powerful underworld organization since he was three years old. After six years, he was rescued by the Special Forces during their operation against that organization and was adopted by the captain of the Special Forces.

Since then, he treated the son and daughter of the captain as his own brother and sister. 

Years later, he joins the greatest VRMMORPG of all time, [Destiny's Fate] online, due to repeated invitations from his brother. He creates havoc inside the game as he climbs his way from being a beginner player to a peak class expert. 

But as he grew up, he became curious about his real identity and his biological parents. He tried to investigate it with the help of his brother and best friend. And after discovering his real background, he decided to follow in his father’s footsteps and stood at the peak of the world using his Martial-Art Skills and Mentalism Techniques.

As Shin was observing Haowin and trying to figure out what kind of hidden combat system mechanic the latter was using, his opponent was also doing the same.

Haowin discovered this hidden combat mechanic after he became a True Demon.

The clues that he had during that time were the rewards meant for the first player to come in contact with the Devildom and Underworld, so it was impossible for other players to also unlock it without him knowing.

At first, he thought that Shin also possessed a 'Perfect Demonification', since their battle capabilities were really on the same level. However, after observing his opponent for quite some time, he discovered that there was something different from the hidden combat mechanics that they had.
