In 2056, in a city in the Yuan Jiang Su Jin area. On the rubble of the 6-story apartment sits a teenager wearing a military suit, bullet-proof vest, and combat boot. On his back was a hexagon shield along with a blood-shadow combat knife. He sat in silence on the edge of the roof. At that instant, the clear sky sparkled and a cool wind blew to greet him. However, there is only silence among the ruins, the ghost town, with the occasional howl that makes your heart flutter.

The existence of a spirit is not as beautiful as the story told. A being who has lived for hundreds of years while making up the world. It was arrogant and cruel, and it was a tribe that saw human life as not even insects. It is difficult for humans to handle such spirits. But only one. There was a human who completely overturned the Gaeul relationship with the spirit.
