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.

"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.

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.

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.

Immediately after defeating Black Goliath, Bell and the others make their way to the surface when they come across a previously uncharted path leading to a mysterious hot spring.

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 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!

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.

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.

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.

Bell and Ryu must cast reservations aside in the face of death. Meanwhile, Welf faces a trial by fire he cannot fail; lives are at stake.
