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...

The original Dungeon adventure continues! After Bell's successes on the Eighteenth Floor, he's the talk of Orario and the gossip has caught him some unwanted attention from Apollo Familia...

After saving the young dragon girl Wiene, Bell's name has become synonymous with "greedy", "despicable", and "traitor." He and his familia have completely lost the trust and respect of everyone residing in Orario. There's no time for him to feel sorry himself when his newfound monstrous friends, the Xenos, need his help to get home. But now that the the greatest obstacle in their way is Loki Familia, does Bell have what it takes to raise a fist against his beloved idol, the Sword Princess Aiz Wallenstein?

"Hello, white-hair." When someone calls out to Bell with these words, he discovers that the voice belongs to a girl who introduces herself as Lilly. Somewhat goaded into teaming up with her despite the many doubts running through his head, Bell has a successful turn in the dungeon with his new companion. Though their alliance is short-lived, the negative rumors swirling about the guild to which Lilly belongs, the Soma Familia, are anything but. Later Bell is confronted by the tales of a mysterious sacred wine said to steal the hearts of all who drink it, and--?!

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...

Having triumphed in the War Game, Lilly, Welf, and Mikoto have forged new bonds with each other and with Bell, and the new-and-improved Hestia Familia is feeling distinctly more familial. But when Bell has to venture into the pleasure quarter of Orario to come to Mikoto's aid, he's soon tangled up in more intrigue than he bargained for. Ishtar Familia owns the night here, and none of Bell's experience can prepare him for their courtesan wiles!

Aiz Wallenstein, the Sword Princess, is known as one of the most powerful warriors from one of the most powerful groups in the city of Orario: Loki Familia. With them, she ventures into the deepest parts of the labyrinthine Dungeon beneath the city, stalking the monstrous denizens that lurk there and vanquishing them with the blazing light of her sword. But when she meets a certain white-haired boy, the encounter will change both of them forever...
