"Battle Net," which was thought to be a game, turned into a disaster for humankind. After the "Space League" was hosted, all living organisms in the universe fought for their lives. Humanity, represented by Earth, kept failing and was eventually annihilated. Except for one person, "Martial Saint" Seong Jihan. His skill, "Nameless Divine Arts," resisted the system’s deletion. Humanity, which had been deemed worthless, received another "chance." This was the second chance granted to Seong Jihan. "Things will be different this time." Since he, the one who completed the game, had returned.
