The Primordial Core is an unconquerable dungeon, the lair of the most powerful monster ever to exist—the Original Monster, the embodiment of evil—Swallow... who just happens to be a lazy boss monster that desires nothing more than sleep. Taking care of this lazy giant is Renee, a homunculus maid whose devotion to Swallow is boundless. At this point, the only one ensuring the dungeon continues to function is Patrick, the last brain cell of the group—and he's a skeleton! Will Mr. Swallow find any peace amidst all this chaos?
