Light Novel Volume 13/Synopsis

Prologue: Team Assignments
Naofumi starts to select the team that will go to Q'ten Lo to stop their attacks on Raphtalia. According to Sadeena, the only way to get to Q'ten Lo is with the help of Siltvelt so they plan to go there first. Naofumi selects Raphtalia, Sadeena, Gaelion, Wyndia, Atla, and Fohl to go on this trip. S'yne uses her vassal weapon to teleport them partway to Siltvelt.

Chapter 1: Advance Payment
The group successfully teleport closer to Siltvelt. However, S'yne notes that in her weakened state that teleporting so many people is dangerous. The party then starts flying on Gaelion's back. Eventually, it was decided that Naofumi and Wyndia would ride on Gaelion's back and Naofumi would teleport back to the village to get the rest of the party whenever they were needed.

About a day away from Silvelt, Filo, Melty, and Raph-chan had caught up with Naofumi. Apparently, Fitoria had asked for Naofumi's help, and for advanced payment, she had bestowed several blessings on Filo and Melty which had greatly improved their stats. Naofumi rejects the proposal and says that he'll take care of it after his time in Q'ten Lo. He then teleports everyone back to the village.

Chapter 2: Sending Word of Our Visit
Back at the village, Naofumi sends Melty to update the Queen on their plans to enter Siltvelt and starts planning the details of their visit to Siltvelt. The next morning, Siltvelt had arranged for a carriage to be prepared thanks to the Queen. Naofumi set Melty in charge of the village and prepares everyone to teleport back on the path to Siltvelt. Atla shows her prodigious skill and the ability to copy Hengen Muso skills. Raph-chan also mutated the ability to level-up. They then teleport.

Chapter 3: Arrival in Siltvelt
Arriving at the saved teleport marker closest to Siltvelt, Naofumi and his party are greeted by emissaries from Silvelt with the carriage. They check for traps on the carriage and then head out. On the way, they start to be surrounded by crowds of people, reverently welcoming him to their country. At the castle, they are welcomed by a representative named Werner to whom Naofumi makes it clear that he is not interested in governing Siltvelt - a country that worships the Shield Hero. His concerns are brushed away and they are shown to their separate rooms.

Chapter 4: Shield of the Beast King
Naofumi was given a huge room just for himself while the rest of his companions shared a small servant's room. The people of the were humbly but firmly controlling Naofumi's schedule and interactions with others. While in his room, Naofumi copied the Shield of the Beast King which had the unique abilities "Beast Transformation Assist" and "Territorial Reform." He was then brought before the Silveltian leadership council.

While most of the leadership fearfully and reverently listened to Naofumi's every word, they all acted as though he was there to stay permanently. In addition, one of the leaders named Jaralis twisted Naofumi's words to solely suit the needs of Siltvelt. Before Naofumi could clear the miscommunication, he was rushed out of the council room so the leadership could discuss plans for the future. Naofumi tried to rejoin the conversation but then all the council members stood up and left Naofumi behind in the room.

Almost immediately after, Naofumi was rushed to dinner with his party and the leadership. Without the leadership giving him a chance to speak, Naofumi switched to his Voice Gengar Shield and used the megaphone ability to talk over everyone. He tries to correct any misunderstandings and then provides Filo's singing as entertainment for the meal.

Chapter 5: Harem
After the party was finished, Naofumi was then led to the bath to clean up. However, as soon as he stepped into the bath, Naofumi was suddenly flocked by hordes of women trying to seduce him. They wouldn't let him leave to pleaded to have his child. Naofumi desperately used his defensive skills to keep the women away and cast cooperative magic with Raph-chan to stop the women. Naofumi's party showed up a few moments too late to help.

Wener deeply apologizes for the event while Jaralis just shrugs it off. When Naofumi asks about the assistance getting to Q'ten Lo, Werner just asks for more time. Angry, Naofumi returns to his room.

Chapter 6: Conspiracy
The next morning, Naofumi goes to meet with his party. In their room, he finds Fohl with a trusted Hakuko that used to work for his family. The Hakuko warns that Werner and the leadership don't intend to follow through with their promise to help him get to Q'ten Lo. The Hakuko demi-humans are apparently trying to help but they no longer have much political influence. Just when he is about to give more details about the conspiracy, they are interrupted and Naofumi is led away from the rest of his party.

At breakfast, Naofumi, his party, and the leadership were presented with a wide variety of dishes. However, Naofumi and most of his party detected poison in the food before eating. Naofumi pretends to eat the poisoned food and commands the rest of the leadership to try it as well. Atla then knocked out all of the Siltveltians who did not eat the poisoned food. Naofumi gave an antidote to Werner and everyone else who did consume the poisoned food. Naofumi then demands that they let them leave to Q'ten Lo. Jaralis, one of the main conspirators, pretends to be fighting to Siltvelt and treats Naofumi like a political tool. Even though his credibility has been shattered, he continues to lie to Naofumi. Atla surprisingly steps forward to Naofumi's defense.

Chapter 7: A True Siltveltian
With passion, Atla calls out Jaralis and his lies. She defends Naofumi with such energy that the remaining leadership becomes fearful of her. She reminds them that Siltvelt was created to serve the Shield Hero, not the other way around. At the end of her speech, the leadership cheer for her, and the newly arrived Genmu Representative calls out her true Siltveltian spirit. Finally, Atla challenges Jaralis to a duel. Fohl and a minotaur war-hero were also added into the fight with the stake being the future of Siltvelt. Reluctantly, Naofumi agrees to the terms of the fight. The battle then begins.

Chapter 8: Honor in Battle
As soon as the gong sounded, Jaralis targeted Fohl while Atla fought the minotaur. Jaralis seemed to have a clear advantage on Fohl however as they warmed up, they both fought equally. While Fohl fought with his fists, Jaralis fought with trick weapons such as smoke bombs, a poisoned sword, and a collapsable spear. Atla easily held her own against the impressively powerful minotaur. In the end, the minotaur was defeated while Jaralis was left battered and bloody. Nearly defeated, he stood up.

Chapter 9: Beast Transformation
Jaralis then consumed a mysterious potion which then healed his wounds and changed into a powerful, modified therianthrope transformation. With his new upgrade, he started to beat Fohl to a pulp. Enjoying his new power, he boasted that he had actually killed Fohl's father and orders his followers to attack the Siltvelt leadership. Naofumi and his party defended against the transformed monsters while Fohl fought against Jaralis. Surprisingly, Fohl was able to successfully transform into his therianthrope form which brought him on par with Jaralis.

When Jaralis saw that he had lost his advantage, he frantically started devouring his transformed followers. As he did so, he absorbed their bodies until he had become a fleshly mass of appendages. Naofumi used his newly acquired Shield of the Beast King to allow Fohl to transform into the legendary beast form. Fohl and Atla - the two Hakuko "half-bloods" - worked together to use a legendary Hakuko attack skill to finish Jaralis off.

After the battle, the Siltveltian leadership gave Naofumi full support and autonomy. Unfortunately, they could not figure out where Jaralis' transformation technology came from.

Chapter 10: Assigning the Heroes
With Siltvelt's full support, a ship to Q'ten Lo was prepared. Naofumi teleported back to the village to pick up the remaining members for the trip to Raphtalia's birth-country. During his absence, the village defended against multiple attacks. The Old Man and Tolly were able to take a look at the attackers' weapons and found that they were created by their master. Along with the Siltvelt group, Naofumi brings the Old Man, Itsuki, Rishia, and Gaelion

Chapter 11: The Flawed Master
Naofumi, with the rest of his group, starts sailing towards Q'ten Lo. On the ship, The Old Man tells Naofumi about his troublesome but talented master. He believes that his master will be able to help Naofumi use even more powerful equipment based on the Spirit Tortoise materials. The ship was suddenly attacked by Q'Ten Lo assassins. After a hard-fought battle, the remaining members of the assassin force were forced to retreat. Before they were able to recover, a whirlpool sucked up Naofumi, Raphtalia, Sadeena, and Gaelion of the ship's deck into the turbulent waters

Chapter 12: A Little Help from the Water Dragon
The kidnapped group woke up in a wet cave. Apparently, the Water Dragon that protects Q'Ten Lo had brought them to his hideout. It had left a message, civilian clothing, and a power-up with a dragon emperor fragment for Gaelion. The barrier which the Water Dragon was supposed to control has been tampered with and will not let anyone from outside of Q'Ten Lo through. Therefore, the Water Dragon had to summon Naofumi and a few others by force to bypass the barrier. It is not happy with the current Heavenly Emperor and would like to set the country back to its role to stop rogue Heroes. Raphtalia gets a message from Raph-chan confirming that the others are being blocked by the barrier. Naofumi and the other three change into the new clothing and enter Q'ten Lo.

While in a town, Gaelion killed a monster that was attacking a child. The officials almost captured him but backed away once they saw he was a vassal of water dragon by his clothes.

Chapter 13: Q'ten Lo Revolutionaries
Apparently, the new Heavenly Emperor had issued a decree that no life - humans, monsters, or animals - can be killed which is why Gaelion was almost punished. This and similar laws have made the people unhappy with the current Heavenly Emperor. As Naofumi and the group approach the lighthouse which controls the barrier, a young man approaches them. After some convincing, the guides them to his father Raluva who is the mayor of this town. They disapprove of the new Heavenly Emperor and have been contacted by the Water Dragon to help Naofumi and his group. They were also the people who helped Sadeena, Raphtalia's Father, and Raphtalia's Mother escape Q'ten Lo.

Naofumi has a strategy meeting with the mayor and his force to decide how to deal with the current leadership. Pushed by his anger at the current leadership, Naofumi decided that they will take over Q'ten Lo. He places Raphtalia in the spotlight as the new Heavenly Empress and encourages the Q'ten Lo people to worship her, much to her dismay.

Chapter 14: Sakura Stone of Destiny
Leaving the mayor's house Naofumi and the rebels head to the lighthouse controlling the barrier. The fought the soldiers guarding the lighthouse. In the middle of the battle, the leader of the enemy soldiers used something called a sakura stone of destiny which significantly weakens Legendary and Vassal Weapons while buffing those who are "blessed" or selected by the Heavenly Emperor. This left Naofumi unable to use any of his hero abilities and required him to use normal magic. When the enemy leader got impatient, he used a sakura stone of destiny ability which drained all of his allies' strength and stats into himself.

During their battle, the nearby sakura lumina tree recognized Raphtalia's authority to the throne and granted her some access to the sakura stone of destiny. They depowered the enemy leader and disabled the barrier to the outside world.

Chapter 15: Sakura Stone of Influence
Out of nowhere, Naofumi and his companions were thrown weapons made from the sakura stones of destiny. The shield Naofumi had received allowed him to selectively un-nullify certain abilities of his Legendary Shield. Looking up, the man who had tossed the weapons was the fool who had tried to hit on Raphtalia. Cooperating together, they were finally able to defeat the leader of the enemy soldier for the lighthouse.

Epilogue: The Old Guy's Master
After the battle, Naofumi's party and Ravula's men celebrate. Naofumi chases the skirt-chasing fool away from Raphtalia and then heads towards the docks. They finally reunite with the group they were split up with. The Old Man Erhard arrives and reveals that the skirt-chasing fool, or Motoyasu II, is actually his old master. Erhard's master promises to back Raphtalia as the new Heavenly Empress instead of the boy emperor currently on the throne.
