Lune has managed to defend itself against the latest Great Tidal Bore, but now there’s a new problem—a team of researchers descending on the city to investigate the dungeon. As they say, “No one knows what happens in a dungeon after a Great Tidal Bore.” The guild’s warning is in vain as the scholars, hailing from the Kingdom’s top organizations, insist on diving in anyway. Whether by luck or something else, the academics and their Crimson Sword bodyguards don’t encounter any monsters. In fact, they don’t encounter much at all as they make their way down—save for a mysterious rift on Layer 10... Meanwhile, Ryo keeps himself busy studying alchemy. On a hunt for knowledge in one of the libraries, he meets a beautiful, intelligent elf whom he can’t stop thinking about. How will the story unfold for our protagonists? Find out in the fifth manga volume of the adventure featuring the strongest water magician who just wants to live life at his own pace!
