Light Novel Volume 3 (Spin-off)/Synopsis

Prologue: Peak Racing
In preparation for peddling, Motoyasu starts creating clothes for Yuki, Kou, Sakura, and Keel. That night, Motoyasu sneaked out with Yuki and Kou to gather materials for the clothing and finished that night. The next morning he goes to meet up with Naofumi - only to discover that in this loop Sakura's filolial queen form looks like a young adult instead of young child.

Chapter 1: Carriage-Crafting
Motoyasu is surprised to see that Sakura's form had changed between loops. Getting over the surprise, he then distributes the clothes he had made for Keel. The group then go to the magic shop to get material for Sakura's new clothes. The magic shop owner allows them to create thread with her tools for free, however it was going to take a while. In the meantime, Motoyasu, Yuki and Kou decide to build a carriage together. Returning to Naofumi, they had just made enough thread before the magic crystal broke.

Chapter 2: A Lazy Pig
Meeting up with the Siltvelt emissary again, they were able to receive the peddling permit as promised. The group then started their peddling enterprise in earnest. Motoyasu finished making the clothes and the group started actually selling medicine. During one of the stops, a girl named Elena asks Naofumi to join the group. Apparently she had been commanded by her father to help out one of the heroes. With her mercantile experience and willingness to be a slave, Naofumi eventually convinces Motoyasu to let her join the group. Motoyasu nicknamed her Lazy Pig since she hardly did anything when they weren't selling product. Whenever the group took breaks from peddling products, Naofumi and the filolials would spend time power-leveling.

While the group were very successful in selling product, it turns out that they were making much profit. Unlike in the original timeline, this loop's Naofumi had a tender heart and would sell medicine for practically nothing for those who needed it. While travelling in the cart, Motoyasu draws pictures of Filo which end up making Yuki jealous.

Chapter 3: A Hidden Passage
While travelling with the cart, the Kou suddenly smells something "tasty" and runs off and grabs a Lumo. Once the lumo is let go, it runs off in terror from the direction it came from. Investigating the source of the Lemo, Motoyasu and Naofumi finds slave hunters who are capturing a group of lumos to sell off. The Heroes run in to save the demi-humans. As punishment, Naofumi decides to get Motoyasu to bring in the slave trader to sell within a different country.

The group of lumos thank Naofumi for his help and even offer to allow the Shield Hero to use their tunnels to bypass the country's borders. Naofumi ends up declining the lead mole's offer and the two groups separate.

Chapter 4: Experts Know Best
As the group continues their travels, Naofumi decides that it's about time to conduct the class-up ceremonies. Motoyasu teleports the group to the dragon hourglass. With a note from the emissary, the group are given access and both Keel and the filolials have the limit-breaking ceremony conducted. After this, Keel starts expressing his desire to learn how to have a therianthrope transformation. Since they are in Siltvelt, a country of demi-humans, they ask around but get very little response. Feeling hungry they go to a tavern where they meet a panda mercenary from Zeltoble. Naofumi bribes the panda to show Keel how to transform with some cute, feminine clothes Motoyasu had made. After a quick commotion, the panda agrees and Keel learns how to transform. As a bonus, Motoyasu can understand Keel in her dog form. The Heroes and the panda's mercenary groups then split up on friendly terms.

Afterwards, Motoyasu investigates how to get a hold of the BioPlants which Naofumi successfully engineered in the original timeline. He apparently found some and planted it in Siltvelt for Naofumi to experiment with later on. With only a few days until the next wave, the group decide to try to improve Naofumi's reputation. After a few days of planning, they return to Erhard's shop. They decide to get two swords for Sakura and two daggers for Keel. It turns out that one of the lumos they had saved was one of Erhard's old friends so they were given a discount. Motoyasu also orders a filolial-inspired armor which uses up the rest of the group's funds.

Chapter 5: An Underestimation
The group slowly make their way to the Melromarc dragon hourglass. When they arrive they meet Ren and Itsuki. While Ren was a little worried about the group, Itsuki was clear antagonistic towards Naofumi. Itsuki tried to warn Keel and the filolials about Naofumi being a rapist, be he is immediately laughed at due to their disbelief. The Four heroes then go to class-up within the church. Ren and Itsuki have their ceremonies completed, but when it becomes time for Naofumi's group to "class-up", they are immediately rejected. Ren immediately becomes suspicious of their preferential action. Regardless, the different heroes' groups split up and prepare for the next wave which is only a few moments away.

Chapter 6: Emergency Evacuations
As the Heroes are summon the Riyute Village to fight the wave, Ren and Itsuki immediately abandon the village to fight the boss. Naofumi's party focuses on evacuating the village and its filolials instead. However, Melromarc's forces rain down attack spells on the group as they are evacuating the village. Ignoring the attack, the evacuation progresses and Motoyasu is sent to fight the Chimera wave boss. With Motoyasu's (albeit greatly restrained) help, the three heroes were able to defeat the boss. Motoyasu collects materials from the defeated boss and gave them to Naofumi to upgrade his shield.
