The time for the final battle has come. These young women-these adventurers-are preparing for the ultimate struggle. No matter who wins, who loses, who lives, who dies, there will be no glory or riches to win. Those who fall shall not be remembered in the annals of history. Even so, they stand strong in the face of the greatest evil the world has seen in 1000 years. This is the story of one more familia...

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"...

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 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...

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!

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.

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...

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...

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.

Now that Rintarou has awakened the power within him, there is something comfortable about his new life...even if he spends his days trying to keep up with Luna's reckless antics. But this current life has come at the cost of Nayuki's. The only way to save her is to get their hands on the Holy Grail, an object that's eluded all search parties since ancient times. As this quest unravels, Rintarou realizes it might be a little more complicated than he imagined...

You don't know what you have until it's gone. Luna is on the verge of death when a new King viciously attacks her using their Jack, Sir Tristan. Meanwhile, Rintarou joins forces with someone who used to be in the Dame du Lac, ready to go up against another version of himself. Neither Luna nor Rintarou are ready to give up their respective fights--especially if it means they have a chance to get back what's precious to them.
