Monsters. Fundamentally different from humans and beasts, these loathsome creatures make their homes underground. To Aiz, such beings exist only to be destroyed, so when they suddenly appear in Orario, she doesn't hesitate to leap into action. As chaos erupts in the streets, Loki Familia rises to quell the onslaught, only to find Bell Cranell standing in their way. Bell seeks to protect the rampaging monster behind him, but in order to do so, he'll have to go up against Aiz herself...

Loki Familia is in dire straits within the artificial Dungeon, Knossos. Separated and forced to face the Evils' cursed weapons, Aiz's wind guides them through the crisis. The wounded adventurers attempt to escape, but several of their number never make it back to the surface...

As Lena suffers Valleta's wrath, Bete's scars begin to ache. In a fit of rage, he charges into enemy territory alone, invoking Hati, the powerful magic that forces him to relive his painful past. It burns all, leaving even his heart reduced to ash. With Bete's fury awakened, his enemies shall know no mercy...

Looking for the key to the man-made dungeon Knossos, Bete ends up going on a date with the Amazon Lena, who has a one-sided crush on him. While he succeeds in getting information from Lena, as the two of them look for the key, they are set upon by a group of assassins! Their fiercest enemy, Valleta, stands in their way, and she's not going down without a fight!

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...

Loki Familia is under attack! Their brief encounter with Kali Familia in Port Meren was just the beginning. The Amazonians and their ruthless goddess have additional torment in store...

Intelligent monsters, the Evils, the Hestia Familia and Aiz's Loki Familia. Head of the latter, Finn alone is calm amid the chaos. In this clash of wills, what path will Finn take? Unwilling to abandon her anti-monster philosophy, Aiz moves to stop Bell, but she finds her path blocked... The battle with the mysterious gale swordsman begins!

Loki Familia has reached the unknown 59th Floor, and it's not quite what they expected. A corrupted spirit, composed of other spirits devoured by monsters, lies before them, and for some reason, it's calling Aiz "Aria"...

The dangerous depths of the Dungeon behind them for now, Loki Familia reunites on the safety of the 18th Floor. But for Lefiya its safety is short-lived when Bell, her rival in Aiz's affection, appears! Already, a new battle is upon her!

Tiona and Tione are locked in heated battle against remnants of their poisonous past, and with Loki Familia tied up dealing with Ishtar Familia's attack, their allies are unable to back them up... Lefiya's life is on the line, but despite the odds, Loki's kids never give up in a fight!

The peerless Sword Princess can't seem to forget the sight of a young boy running away from her. Watching his receding back brings up memories from her own past and she begins to question her sole ideal of devoting everything to become stronger. For the first time ever, is Aiz is a bit troubled by her heart like any normal young girl??

Aiz and Bell's secret training pays off...!! As Loki Familia finishes preparations for their expedition to the 59th Floor, they're not the only group headed back to the Dungeon. But it's like Dejavu when Aiz hears of a white-haired adventurer and a Minotaur, and she bolts away from her Familia to check on Bell!

Of all the people Lefiya could end up lost in a forest with, it had to be her sworn rival, Bell Cranell! Together they must find their way back to the Loki Familia camp, however it seems the Evils that have plagued them on other floors of the Dungeon follow them even here, on the "safe" Floor Eighteen!

Just strength. That's what I need for my wish... There has been a sudden shift, and suddenly the reason for Aiz's desire for strength has changed...Is it Bell? Aiz has finally reached her goal of ranking up to level 6! What new adventures await her now in the dungeon...?

As Loki Familia investigates Daedalus Street and the many mysteries it contains within its labyrinthine streets, evil eyes follow them...Deep beneath Orario an entirely different challenge from the Dungeon awaits!

"Aria, go the fifty-ninth floor." With that message, Levis leaves Aiz with still no answers but a claim she can find what she needs deeper in the dungeon. The deadly clash on the twenty-fourth floor over, Aiz and the others return to Orario to deal with their losses. However, Aiz and the rest of Loki Familia are not long for the surface as they declare an expedition to unknown dungeon territory: Floor fifty-nine. Preparations begin and Aiz finally makes progress in her relationship with Bell...

"I won't forget." The Dungeon calls adventurers deep into its labyrinth in search of personal growth, strength, and experience. But the dungeon is a tough master -- one wrong move, a bad choice, and permanent death awaits. Lefiya, Bete, and Filvis have gone deep into the dungeon in search of Aiz, but have instead found a far more dangerous foe...Will they escape the wrath of the dungeon or be forever doomed?

Now Level Six, Aiz has returned to the dungeon to test her new skills and picks up a new quest while she's there. Traveling with adventurers from Hermes familia, they journey deeper into the dungeon. But when the Red-headed Tamer shows up again, will Aiz's new level be enough to keep her, and her teammates, alive?

Aiz and her friends make their way to the town nestled deep within the Dungeon only to stumble upon a macabre murder! After determining that culprit must be extremely powerful, the manhunt begins but everyone seems to think that the Loki Familia might be the most likely suspects?! On the surface, Loki embarks on an investigation of her own, delving deep into the sewers to get to the bottom of a mystery that may affect the future of all her children--and Orario as a whole...
