With Haruhime safe at the Familia, things begin to calm down. But when Hestia makes a casual pass at Bell and he shuts her down hard, she runs out of the mansion and into the waiting arms of kidnappers!

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.

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.

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.

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.

"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 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...

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

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’s exploits have earned him fame and a new alias, and Lili worries that means change is coming. Meanwhile, Ryu left a note for her coworkers and vanished soon afterwards.

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.

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.

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.

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's back with a new adventure! When the powerful leader of the Apollo Familia takes notice of him, his life with his Goddess is under threat.

With the true purpose of the ritual and the killing stone revealed, Bell decides that he's going to take any risk to save Haruhime.

"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.

Bell defeats the minotaur and becomes the fastest adventurer to level up in history. After his success, Bell is given the nickname "Little Rookie." As he sets his sights on the middle floors of the dungeon, Ryuu tells him that if he wants to succeed, he's going to need a bigger party.

Bell goes to train for the War Game, and it's up to the rest of the party to rescue Lili. Hestia puts her plan into action, but Lili refuses to leave the Soma Familia.

Gather your party and venture forth, Bell. The dungeon awaits.

Freya loved a mortal who would never love her back, and both she and others suffered for it. The conflict she started is ending, and the goddess must face her final fate.

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.

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.

The party is exploring on the middle floors when another group leads a huge train of monsters to them. They're overwhelmed and caught in a cave-in. Cut off from the upper floors, with limited supplies and little strength left, they are forced to make a desperate attempt to reach the safe zone even deeper in the dungeon.
