Chapter 1: Soulmate
Before going to meet the Siltvelt leadership, Naofumi and Motoyasu have a heart-to-heart conversation. Motoyasu tells of his life before he was summoned to be a hero and encourages Naofumi to not fall into the temptation of women attempting to seduce him. After their conversation, Motoyasu uses concealment magic and skill to scout out the castle. He finds Jaralis and his conspirators talking about Naofumi. After learning that the conspirators plan to force Naofumi to have children and then kill him afterwards, Motoyasu kills the whole group.

Rejoining with Naofumi, he finds that the Shield Hero had just barely escaped a horde of women who were waiting for him at the bath. Motoyasu was about to kill them, but Werner and then the genmu representative arrive after hearing the fuss. While Werner didn't help, the genmu representative stopped the girls and convinced them to leave. The genmu offers his help and advice and then the heroes' party returns to their previous activities. Eclair also plans to contact Queen Mirellia to help protect the Shield Hero.

Naofumi, Motoyasu and their group had spent 3 days in Siltvelt. During that time, they've had to protect Naofumi numerous times from women. That morning they have breakfast with the leadership, but Sakura reveals that her food was poisoned. It seems like the remaining conspirators are trying to kill both Sakura and Motoyasu for protecting Naofumi from the women. Angry, Naofumi demands that they find who is responsible for the poison. The terrified Siltvelt leaders agree and try to calm him down.

Chapter 3: Beast Spy
As a show of power, Naofumi asks Motoyasu to destroy the nearby mountain and the leadership prostrates themselves further. With this moment, Naofumi demands that all marriage proposal stop until he defeats the oncoming wave. Upon asking about the Rhubaldt, the Vassal Claw hero, Werner reveals that they are suspicious of his followers of opposing the Shield Hero.

After the Siltvelt leadership leave, Naofumi and his party discuss the situation. Apparently Eclair was successful in contacting Queen Mirellia and they just need more time to prepare. While they are discussing, the Vassal Claw Hero arrives. The Claw Hero initially impresses Naofumi and Motoyasu but suddenly the Legendary Spear starts suggesting a skill "Beast Spy." Upon activating it, the spear immediately attacks and kills the Vassal Claw Hero. Every is shocked and are about to attack Motoyasu but as the dust clears, it is revealed that a fox woman was using illusion magic to pretend to be the Claw Hero. Surprised, the delegates apologize and Naofumi and Motoyasu decide to eventually look for the real Claw Hero.

As a reward for his services, Werner offers Motoyasu a reward of his choosing. Motoyasu decides that he wants money to buy as many filolials as he can from Melromarc.

Chapter 4: In the Back Alley
Teleporting to Melromarc, Motoyasu arrives at the destroyed Riyute village. It seems that, with Naofumi's absence, the Heroes could not defend this village during the second wave. While walking in Castle Town, Motoyasu bumps into Ren. Strange enough, Ren actually wants to talk with Motoyasu.

Ren reveals that with Naofumi and Motoyasu gone, the country is slowly falling into ruin and gloom. Itsuki has been treated extremely well by the royal court, but one of his companions was suspiciously killed by "The Church of the Shield". Ren and Itsuki are being pushed to match the power of Motoyasu, claiming that he and Naofumi will declare war on Melromarc. In the end, Ren doesn't trust King Aultcray and Malty and has decided to leave for Zeltoble.

Afterwards, Motoyasu goes to the slave trader's tent. With the various rumours of Motoyasu's eccentricity and destructive power, the terrified merchant sells all of the aria-type filolial eggs that he owns. Motoyasu then teleports them all to Siltvelt. That night, Motoyasu enters The Church of the Three Heroes and destroyed everything and everyone inside. He then did the same with the Melromarc castle. However, he was not able to find the pope, King Aultcray or Malty. Going back to Siltvelt he meets Naofumi who chastises him after learning what Motoyasu had done.

Chapter 5: Shieldfreeden
The next day, the army of filolials Motoyasu bought had started to hatch. He tasked both Yuki and Kou to train and level-up this army. During this time, Naofumi had started helping out around the countries and the two heroes had started their search for the claw hero. After wondering about the difference between Siltvelt and Shieldfreeden, Naofumi learns that the Vassal Hero in Shieldfreeden should arrive in roughly a day.

Chapter 6: The Seven Star Whip Hero
The next day the Vassal Whip hero arrives in an airships. He introduces himself and asks to look at the body of the false Vassal Claw hero. While Motoyasu's memory is incredibly fuzzy, he suggests that Naofumi should be careful around this hero named Takt. That night, Naofumi and Takt get to know each other at a reception party put on by Siltvelt. The next day, Motoyasu and Naofumi are invited to Takt's airship.

Naofumi and Motoyasu enter the luxurious airship but as they meet Takt they are immediately attacked by him and his harem. Apparently, the false claw hero was one of his harem. As they are attacked, Motoyasu suddenly remembers all of the evil deeds Takt did in the original timeline.

Chapter 7: Half-Burnt Charcoal
Remembering the many filolials which died during the fight against the Phoenix and Atla's death due to Takt, Motoyasu starts an uncontrollable rage. He kills Takt and Ellie in a single blow. He kills the griffin (Ashil) while a dragon in Takt's harem starts to cause massive destruction. Motoyasu then kills the dragon (Leludia) and Naofumi gets him to calm down.

Even with the power-houses of Takt's harem dead, chaos erupts. With only 10 minutes until the next wave of calamity, Melromarc's army had decided to attack Siltvelt and will arrive in three days. Motoyasu, Naofumi and members of the Siltvelt army are teleported to the wave. However, they are able to defeat it easily. Returning to the Siltvelt castle, they learn that Itsuki is part of the approaching Melromarc force. Motoyasu suggests using information contained within the the defeated dragon's core to conduct a ceremony which allows people to surpass level 100.

Chapter 8: Remnants
The next three days, Naofumi, Motoyasu and Siltvelt prepare for war against Melromarc. Just when the army was about to arrive, Siltvelt receives news that Shieldfreeden also declares war on them. Nelshen, one of Takt's harem who survived, had convinced the country to war against Siltvelt for revenge. In order to prevent further destruction, Naofumi and Motoyasu decide to get fully involved in the war. Before they go out to fight, Naofumi makes Motoyasu promise to try to avoid starting wars if he ever restarts again.

In order to take care of of airship with bombs and machine guns, Naofumi forces Motoyasu to ride a dragon to confront them. Since dragons are the natural enemy of filolials, Motoyasu detests the idea, but he is eventually convinced.

Chapter 9: Lingering Fragrance
Motoyasu and Naofumi ride the dragon to intercept the airplanes. They are able to destroy the airplanes and they return back to the ground. Despite their victory, Shieldfreeden continues to attack Siltvelt. At this point, Melromarc also arrives. Naofumi and Motoyasu learn that the army includes the pope which wields the Legendary Replica weapon which can replicate any of the four legendary weapons. It is determined that the Siltvelt army will confront Shieldfreeden while the Heroes are the filolial forces will confront Melromarc.

As Naofumi and Motoyasu meet the Melromarc army, they are met by Itsuki. Unlike when he was first summoned, Itsuki is now full of hate for Naofumi and Motoyasu. Apparently, he had been lied to and manipulated by Malty and Aultcray to fight the "evil" Naofumi and Motoyasu. Naofumi tries to talk, but Itsuki won't listen and attacks.

Chapter 10: Carved into the Heart
As the Melromarc forces attack, it becomes clear that they cannot defeat Naofumi and Motoyasu. Even before the main fight begins, Melromarc soldiers loyal to Queen Mirellia and lead by Eclair come to assist the Spear and Shield hero. With an official notice from the queen, King Aultcray is stripped of his authority and his forces are considered traitors. However, King Aultcray, the pope and Itsuki continue the fight.

Motoyasu confronts the pope with the replica weapon and easily destroys the two. Itsuki confronts Naofumi but Motoyasu then paralyzes the Bow Hero. With the Melromarc army defeated, Malty attempts to run away but Motoyasu stabs her in the back and then annihilates her. As Itsuki remains paralyzed, one of his companions (Mald) denounces him and calls him a fake her. Before Motoyasu and Naofumi could response, Itsuki is killed by his own companion. Realizing Motoyasu is about to be reset, Naofumi says his goodbye and reminds the Spear Hero of her promise to prevent war. Motoyasu is then sent back in time to when he was first summoned.
