With their new money-making scheme in place, Dead End head out to track down a mysterious monster. Unfortunately, the job doesn’t go as smoothly as they hope, and Rudy’s plans may turn out to be a lot less safe than he thought.

Dead End discovers that Ruijerd will have to pay a fortune in fees to leave the Demon Continent. As they struggle to find a way around this unexpected roadblock, Rudeus receives another vision.

Roxy arrives on the Demon Continent to begin her search for Paul's missing family. Meanwhile, Rudeus strikes a deal with smugglers to transport Ruijerd across the ocean.

After setting out from Millishion, Rudeus, Eris, and Ruijerd board a ship back to the Central Continent. Meanwhile, Roxy arrives in Rikarisu, where she encounters some familiar faces.

Rudeus sinks into depression following Eris's departure. As he struggles to get back on his feet, the many people he's met continue their own journeys.

Rudeus and Elinalise reach Rapan and soon reunite with Paul, only to learn that a deadly labyrinth has claimed both Zenith and Roxy. The fruits of Rudeus's studies offer a last, faint hope to reach his mother and his mentor in time.

With Roxy's rescue, the search for Zenith resumes in earnest. Rudeus reconnects with his mentor amid the perils of the labyrinth. But why does she seem a little more awkward around him than before?

The rescue party reaches the heart of the Teleporter Labyrinth and confronts its guardian. But when the monster shrugs off Rudeus's magic, they realize they may have bitten off more than they can chew.

Roxy makes a desperate move to pull Rudeus out of his depression. As the group journeys home, both of them must face their feelings and negotiate the consequences.

Rudeus arrives home, frantic that something may have gone wrong in his absence. But the conversations waiting for him may become disasters in their own right. How can he introduce a new wife to a family still reeling from Paul's death?
