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.

Chapter 7: Rebirth of the Paradox
With the Heroes' first wave complete, they are all invited to the Melromarc castle to celebrate. Almost immediately after the celebrations start, Itsuki storms toward Naofumi and accuses him of having slaves. Naofumi agrees that he owns slaves a gives strong reasons why he should be able to have slaves. Hearing the commotion (which he had initiated), King Aultcray declares a duel between Naofumi and Itsuki. After quick preparations, the duel begins

Chapter 8: Bad Status
Unlike the original timeline, this version of Naofumi is significantly powered up. All of Itsuki's attacks either do no damage or Naofumi can swipe them from the air. However, Naofumi can only do small damage at a time. However, Naofumi used a paralysis poison to incapacitate Itsuki. Malty tried to interfere like in the original timeline, but Naofumi's stats made the attack ineffective. Suddenly, the king commanded everyone to attack Naofumi to "save" Itsuki.

Seeing the king interfere with the duel, Ren angrily objects and declares the duel over. Itsuki collapses due to the poison and Naofumi and his team leave.

Chapter 9: Unfair
The day after the duel, the four heroes assemble at the castle to receive their reward for their efforts in the wave. Itsuki gets a substantial reward while the others get much less.

After the rewards are dispensed, Naofumi, Motoyasu and Ren have a private conversation in an alley. Naofumi and Motoyasu plan to stay in Melromarc while Ren plans to leave for Zeltoble. They also try to tell Ren about the different power-up methods but Ren doesn't believe in them enough to unlock them.

Chapter 10: The Egg Raffle
After the three heroes finish their conversation and Ren leaves, the other two go to the slave trader's tent to look for Filo. With the same timing as the original timeline, the slave trader offers them to try the egg gatcha game which contains both filolial and dragon eggs. Using the information of the requirements to raise a filolial queen as leverage, Naofumi convinces the slave trader to leave only the filolial and dragon eggs in the game. They then buy a single egg.

After leaving the slave trader's tent, they go to Erhard's shop. Erhard tells them that the Medicine Shop Owner and the Magic Shop Owner want to thank them for saving their families in Riyute. From both they get a book of medicine recipes, have their magic affinities determined and receive a book to magic spells. The group then begin their travels, starting with Riyute. Their the villagers who are cleaning up the monsters and chimera remains thank them. They then continue their travels.

Chapter 11: Dressing Up the Panda
The next day, the party then portal over to Siltvelt where they find Larsasuza again. They agree to level up and go hunting together. Before that, they give Lars and cute outfit which she embarrassedly tries on. When her group of mercenaries arrive, they are in awe at her newfound charm. The heroes and the mercenaries then make a plan on how to divide their hunting parties.

Before the hunting begins in earnest, Motoyasu takes the groups to where he had be experimenting with BioPlants to find the wasteland overrun with the plant monsters. The groups fight the dangerous monsters and eventually defeat the main plant. Naofumi absorbed the remains, hoping to be able to modify them like in the original timeline. The egg that the group bought from the slave trader hatched into a navy filolial.

Chapter 12: The Fruit of Idleness
Excited with the new filolial, the group discuss what to name her and they end up calling her Luna. Experimenting with his new plant adjustment abilities, Naofumi and Elena agree to start the adjusted crop on Elena's family's land. As they were dispersing the seeds, Luna matured into her filolial queen/angel form. Finding that her colouring between her filolial and angel form are quite different (like Filo), the group hypothesize that the chimera meat they had been feeding her is responsible. They also learn that Luna has the unique ability to transform into a chick form.

The group then continue their peddling operation with both bioplant food and medicine to help the poverty-stricken Melromarc. Naofumi also takes the chance to learn more medicine and how to cast magic. Upon discussion they realize that Hickwaal was likely the one who taught Naofumi how to make accessories in the original timeline. Since that didn't happen in this loop, they decide to buy through Elena's mother.

Chapter 13: Tourist Attractions
During their peddling adventures, the group arrives in Mirso Village where Ren had recently slain a certain dragon. The town has become a tourism town filled with adventurers who all want a part of the rewards from returning monster materials. The group find it weird that no one is bringing back parts of the dragon itself so they decide to try themselves. Arriving at the dragon, they find the corpse protected as some kind of landmark to attract tourists. Motoyasu foggily recalls that they shouldn't leave the corpse lying around but the group decides to head further into the mountains.

They eventually find a bunch of adventurers from the village at a den. The greedy adventurers had just found a demi-human girl who they intended to sell as a slave. Keel confronts them. Using his influence as the "Saint of the Bird God", Naofumi intimidates them into stopping immediately. Frustrated, the adventurers step back and Naofumi attempts to help the demi-human girl they were about to capture. The young girl introduces herself as Wyndia. The large dragon Ren had killed was her father and the young dragon she is currently with is her little sister. Upon Wyndia's request, she is shown her father's corpse and she and her sister grieve.

Chapter 14: The Doctor's Assistant and the Dragon Girl
After grieving their father's death, the two decide to join Naofumi and Motoyasu. The young dragon is given the name Gaelion and promises to try to become stronger. Naofumi also notices that Motoyasu doesn't see Wyndia as a pig. Motoyasu reveals that she was the assistant to Filo's doctor and thus he sees her as an ally and a normal person. Despite the natural hatred between filolials and dragons, the two have a friendly (albeit very competitive) relationship.

Epilogue: To Filolials, I Sound My Cry of Passion
Returning to Mirso Village, Naofumi warned the town representative of the dangers of having a rotting dragon's corpse and the group leaves the village. Motoyasu re-affirms his goal to find Filo and impresses Naofumi with his perseverance despite going through many different time loops.
