Noir and his friends spent the last days of summer vacation saving the town of Honest from a monster siege. Now they get to meet a king! From there, it's back home, back to school, and back to exploring the infinite labyrinth of the hidden dungeon. Noir has a new mission, after all: free his master Olivia from her curse, no matter the cost.

Noir needs to make the most of the last days of summer. A letter from his older brother Gillan, studying to be a merchant in a neighboring kingdom, gives him the perfect idea: road trip! Accompanied by his friends, Noir heads to the town of Honest. But when they arrive, they find a city besieged by monsters! Noir's peaceful summer vacation is about to get way more exciting than he bargained for!

Hidden dungeons--legendary places that no one knows how to enter--are full of extremely rare items, incredibly dangerous beasts, and strange beings that can grant power beyond measure. Noir, the third son of a penniless baronet, just lost his job. He was contemplating becoming an adventurer when fortune struck only a mile from home, and he opened the entrance to just such a dungeon!

Noir is determined to enjoy his hard-won summer vacation. He has a new friend in a rival guild, a shop to open, and more levels of the hidden dungeon to explore. But with the thief known as the Phantom on the loose in town, Noir's peaceful days may soon be stolen. Worse, his best friend Emma may know something about the Phantom--something she doesn't want to tell Noir.

As a full-time student and adventurer, Noir spends his days fighting monsters, studying for exams, and flirting to power his special skills. Whenever he can, he returns to the hidden dungeon to continue his secret training. But something unexpected awaits him on the dungeon's seventh floor--a vast forest, a young girl named Dryade, and the monster who wants to devour her!

At long last, Noir has released his master, Olivia, from the Death Chains that kept her bound in the hidden dungeon. But before she'll agree to train him in earnest, he'll have to earn one hundred thousand LP! On top of that, the Hero Academy is about to kick off its annual series of competitions to determine the king and champion of the school. And then there's the new girl in town, Mira Santage, treasure hunter extraordinaire. With all the excitement, Noir's going to have to give his all to prove he's worthy of his master's tutelage.

What does it all mean, and why has Claire been talking to herself so much lately...?

Bell, along with his adventuring party of Welf the swordsmith and Lilly the supporter, has made it into the middle floors of the Dungeon, but the schemes of another party have stranded them there! Hestia's going to need to send help, but will the rescuers arrive in time to save Bell and his friends from the monster that's got them cornered? The familia myth of the boy and the goddess continues!
