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.

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.

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'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.

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.

It's time for the War Games, and the Hestia Family, and its new members, are ready. Can they defeat the entire Apollo Familia and save Bell from Apollo's clutches?

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.

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.

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.

The Ishtar Familia's plan has been found out by Freya, who launches a raid on their home. Just when things are bad enough for Bell, their interference brings even more chaos!

Monsters are evil abominations driven by murderous instinct. But if that were true, why is this one a scared little girl who doesn’t understand why she’s being hunted?

Although Ikelos has been successfully scapegoated, public opinion turns on Bell. Helping the Xenos will now prove impossible — but Hermes’ intel might just change the tide.

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

The party learns too late that the Moss Huge can use other monsters against them. Meanwhile, Bell is alone, but not without allies; the Xenos have not forgotten his kindness.

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.
