Motoyasu and Naofumi have finally come back to Melromarc after a long journey of trading and leveling up. With their new funds, they decide to upgrade their equipment.

Summary
After separating from Larsa, Naofumi and Motoyasu's heads out and cooks their own meal. Motoyasu also reveals that he took the dangerous BioPlant and is starting to experiment with it for funds.

The net day, the group heads to Erhard's shop for equipment. Naofumi passes him a letter from one of the Lemos that they had saved earlier. To Erhard's surprise, it's from one of friends from years ago. The letter outlines the Lemo's gratitude so Erhard offers doing some work for free for Naofumi and Motoyasu. Naofumi shows the materials they have gathered and Erhard believes that he can make good equipment. Discussing what they want, Motoyasu and Naofumi determine that they want equipment for both Sakura and Keel. To Naofumi and Erhard's disbelief, they both want to duel-wield swords.
