In search of the key to Knossos, Bete’s leaving no stone unturned! But unfortunately for him, Lena seems to have the information he needs, and her price is one date! Though he reluctantly agrees, they don’t get far before they’re set upon by Valletta and her horde of assassins, and she’s taking no prisoners! Outnumbered and ill-prepared, will Bete be able to protect his unlikely companion?

Loki Familia has breached the halls of Knossos, a man-made underground labyrinth with nasty surprises lurking around every corner. Divided into several groups, the members have their hands full just trying to survive! Bloodied and battered, will Gareth, Finn, and the others be able to escape this living nightmare, or will Knossos be their final resting place?

Loki Familia's supposed beach vacation has taken a turn toward catastrophe with the appearance of demons from Tiona and Tione's past-the Kali Familia. The unexpected arrival of the Amazonians unhinges Tione, and both sisters must confront memories best forgotten. Before it becomes clear exactly why Kali and her brood have dropped in, tragedy strikes-Lefiya is kidnapped, and Tiona and Tione vanish in the uproar. The goddess Loki's wrath is a thing of horrors, but the Amazonian sisters' ire may just prove worse...

The clock stops for no one. Promises have come undone-Aiz could not kill the monster who wept in front of her while shielding Bell. For nights on end, those tears have haunted her, obscuring her reason to fight and guiding her to face Bell for the first time since their conflict... But they aren't the only ones joining hands across familias. With the dawn of the Knossos operation upon them, the patron gods tear down their differences. The adventurers march toward their fate with the Xenos by their side. For life, for death, and for the destiny of Orario, they hold their heads high, ready for war-failing to realize that the darkest of times is yet to come...

Aiz has finally done it! After showing her resolve by defeating the Black Skeleton King, Udaeus, she has reached Level Six at long last! But instead of being satisfied, why is she rushing back to the Dungeon?! With no idea as to Aiz's whereabouts, Loki Familia is determined to take action. But there are too few of them available to form a search party, forcing Loki to accept the help of another familia...

Hestia Familia and Loki Familia. One is trying to save the Xenos, intelligent monsters whose origins are yet unknown. The other sees them as nothing more than typical monsters—enemies to be exterminated. As Bell stands before his idol, Aiz Wallenstein, he knows a clash of wills is inevitable...

After returning from an arduous but successful expedition deep into the Dungeon, Loki Familia gets a rare chance to rest their weary bones. Ainz is troubled about a certain rabbit-like boy, but that won't stop Lefiya and the others from dragging her along on an all-girls shopping trip! What's more, the Monsterphilia is fast approaching, promising a day filled with exciting attractions and events. But the gods and mortals of Orario may get more entertainment than they bargained for when all Dungeon breaks loose!
