Abaddon, the demon that overpowered Gods and Devils, has gone from the strongest and most intelligent boss monster to a mere Level 1 human. Four years after the immortal humans migrated to Megrove through unknown means, Abaddon realized that this world was just a cage. He learned that to the immortal humans, it was just a form of entertainment, that all of his achievements and hard work was bound to be trampled on by these limitless immortals. After his enlightenment, he suddenly wakes up in an inn as a Level 1 human named Kezner. Kezner now has the ability to actually go to Earth for only 8 hours a day, but with the possibility of staying there forever. With the goal of living with the so-called "true Gods and Devils", Kezner was now about to learn the hard way why Sanctuary of the Divine was a passtime.
