Earthling's journey to another world and get magic was a common thing. What if otherworldly beings came to earth and learned modern warfare? That's how Jakel Varg del Valora's story began. He was a prince of a kingdom of a long-lived race that had been oppressed by earthlings who came to his world.

25 years after Earth's connection to Ethereal, the Walkers, a group of humans who freely walked through the portal, were at their peak. The system made their lives so easy that a loser could be a champion. Aware of their power, they stepped out of line. Walker conquered everything and committed so many atrocities. The Kingdom of Valora, Varg's homeland, was on the brink of destruction. They had no choice but to use the same trick.

While Walker became the hero of the gods in Ethereal, Varg came to Earth and became a special force operator.
