Lonely King shocks the gaming community by acquiring the game's only SSS-level magic pet, the Nine-Tailed Sacred Fox, which turns out to be weak and primarily boosts luck rather than combat strength. Skeptics mock the useless pet and offer to buy it cheaply, but Lonely King refuses to sell. Suddenly, the game merges with reality, forcing all players, including Lonely King, into the digital world where in-game death means real death. As he adjusts to his new reality with his pet, Lonely King faces the daunting challenge of surviving this apocalypse while determined to collect seven keys to restore his lost grandmother.
