With retreat an impossibility, Bell’s party fight for their lives when a Floor Boss spawns early. However, they are all adventurers; they will not die so easily.

Ryu, the Gale Wind, stands accused of murder. Bell and his party need answers, but only Cassandra knows that tragedy will befall them if they pursue their friend.

With Lili's help, Bell is progressing further into the dungeon than ever. Since he can focus on the fights, he can make more money. But Lili has a secret: she despises adventurers, and is waiting for a chance to trick Bell.

Bell and Hestia spend a relaxing few days at a village in the wilderness, and participate in a local festival. Bell ponders what to do about his relationship with his immortal Goddess, and if he really is ready to love her.

Some monsters you must fight and from others you must flee. But beware the Juggernaut lest you simply cease to be.

The Hestia Familia was victorious in their battle against Apollo, and now they've won a huge mansion and a giant pile of cash! Hestia sets out to recruit for the Familia, but there's something she's forgetting...

A massive floor boss has crashed down from the upper floors and begun tearing apart the adventurers. Aiz has left for the surface, and it's up to Bell and his friends to defeat the monster. With their escape route cut off, it's do or die if they ever want to see the light of the sun again.

Bell and Ryu’s relationship deepens as the trauma of the Deep Floors pushes them past their limits. They have each other, and that is the only reason they’re both still alive.

"Excuse me, are you looking for a supporter?" After his rapid growth, Bell reaches the 7th floor of the dungeon. He gets new equipment and is ready to go when a girl named Lilika approaches him. She is a supporter, and her job is to aide adventurers in the dungeon.

The Labyrinth city of Orario has a massive dungeon at its heart, filled with terrifying beasts. A new adventurer, Bell Crannel, challenges this perilous labyrinth, but not in hopes of finding treasure, but in hopes of picking up a girl.

Bell Crannel's power grows rapidly thanks to his ability, Realis Phrase. As long as he's in love with a girl, it will continue to make him stronger. His goddess, Hestia, is jealous that the girl he's in love with isn't her, but still wants to support him. She goes to another goddess and asks her to make him a powerful sword.

Lili leads Bell deep into a dungeon and abandons him. He's alone and surrounded by larger monsters than he's ever faced. She runs off with his knife and makes for the exit, but her guild mates are waiting for her.

With the help of Haruhime the Renard, Bell escapes from the Amazoness prostitutes. But he begins to wonder about Haruhime, who says she was forced to be a prostitute against her will and isn't worth being saved.

"I don't want to lose any more of my family." Bell and Hestia are attacked by an escaped monster during Monster Philia. Bell fights to save the only family he has left, but is overwhlemed by the monster.

After a great struggle, Bell and his party finally reach the 18th floor. Aiz Wallenstein and the Loki Familia are already there, returning from their expedition to the lowest levels of the dungeon. With the danger passed, they enjoy a short break before they head back up to the town.

Bell and his party are making good time and will soon enter the lower floors. But the dungeon crawl is going too smoothly, and Cassandra cannot shake her earlier premonition.

Ryu couldn’t be the killer… right? Bell wants to help his friend, but as the body count grows higher, he must ask himself how well he truly knows her.

Critically wounded and trapped within the dungeon’s darkened depths, Bell and Ryu’s adventure is over. Their fight for survival has now begun.

The boss fight extracts a heavy toll on the party, and they must make a choice. If they go one way, they will live. But if they go the other? They will die.

The party narrowly survived, and now they must search for their missing friends. However, they’re facing more than just monsters; they’re fighting the Dungeon itself.

Hope glimmers in the darkness; the Xenos appear in the party’s hour of need, and Bell and Ryu make steady progress despite all odds. They may all survive this after all.

At Bell's urging, Hestia reluctantly lets Lili into the party. Bell, worried about his weakness as he continues to go deeper into the dungeons, accepts an offer of help from Aiz Wallenstein, the girl he loves.

A massive floor boss falls from above and traps the adventurers. The only way out is up, and to get back home Bell will have to defeat it without Aiz's help.

Bell is caught up in a new adventure that takes him to the seedy underbelly of Orario: the pleasure quarters.

Bell decides he's going to get money in the dungeon to purchase Haruhime. But he runs into a trap when the Ishtar Familia decides to kidnap him.
