In this episode, Sato is involved in a battle over a new dungeon called Selen. The dungeon has ten floors, with vegetables falling on the odd-numbered floors and meat on the even-numbered ones. Two factions, Secro and Hetero, are fighting for control of the dungeon.

Sato's partner Emily has a unique ability that makes her tent extremely comfortable. While exploring the dungeon, they encounter a rare monster on the first floor. Thanks to Sato's unique ability, they manage to obtain the rare loot, soybean sprouts, giving Secro an advantage. However, Hetero employs a strategy to sabotage Secro's chances by sending F-rank adventurers to reduce the odds of rare loot appearing.

Sato devises a plan to counter this. He proposes increasing the reward for finding rare monsters to ten million, ensuring that if he defeats the monster, he is guaranteed to receive rare loot. With this strategy, Sato successfully secures rare loot from floors 3, 5, 7, and 9, securing either a draw or victory for Secro.

However, the victory does not come without challenges. Sato is confronted by a group of adventurers who possess the F-rank final loot and are furious that Sato's success has rendered them obsolete. A fight breaks out, but Sato manages to fend them off with his unique abilities and his determination to return safely to Emily.

The episode ends with Sato returning to camp, where Emily and the others warmly welcome him back.
