Light Novel Volume 6/Synopsis

Prologue - Cal Mira Superstitions
In the aftermath of the wave at Cal Mira Archipelago, Naofumi decides that he needs another party member. Walking around the marketplace, he noticed a crook merchant selling accessories at incredibly high. Naofumi uses his connection with Hickwaal to intimidate the crooked merchant and teaches 'proper' business practices. The Queen then arrives and leads Naofumi to the second four-heroes conference.

Chapter One - The Seven Star Heroes
With the last battle against the Heroes of Glass' World, it was clear that the three attack heroes - Ren, Itsuki, and Motoyasu, were not strong enough. Naofumi tried to tell them that all of the different power-up methods they used actually worked together. The other heroes refused to believe him and continued to call his Wrath Series Shield a cheat. Focusing on the attackers from another world, Queen Melromarc suggests that it might work similarly to the Seven Star weapons on their world. These Seven Star Wielders are either adventurers of this world or people that are summoned that eventually earn the right to wield the weapons to assist the Four Legendary Heroes. The Queen decides that the 4 heroes need formal training.

In a private discussion with Naofumi, the Queen expresses worry about the other 3 heroes and mentions that the Seven Star Heroes are stronger than them currently.

Chapter Two - An Unhappy Girl
On the way back to his room, Naofumi meets Rishia - overloaded with errand items for Itsuki. Naofumi helps her and on the way back Rishia explains how Itsuki had saved her. Now she feels like she needs to repay a debt to him. However, Itsuki has not been treating her well and is not even using her strengths.

Back in his room, he explains the result of the conference to Raphtalia and Filo. Fitoria listens to the conversation through Filo and mentions that she has fought other people coming out of the rift of the waves before. She also promises to continue to help with the waves.

Chapter Three - Framed Again
Naofumi walks by the ocean when he sees Motoyasu trying to calm the crying Rishia. When Motoyasu sees Naofumi, he shoves Rishia to him and moves away. Rishia is crying but explains that the Spear Hero was trying to cheer her up. She then apologizes to Naofumi and runs off.

The next morning, Naofumi asks Motoyasu why Rishia was crying. When Naofumi learned, he crashed in Itsuki's room for an explanation. Apparently, Itsuki was jealous of the praise she had gotten from the Queen. One of his party members broke the accessory and then framed Rishia. When Rishia arrived to his room, Itsuki immediately kicked her from his party. When Naofumi found proof that she had been framed, Itsuki then said that they won't let her back in for her own safety. After a confrontation with Itsuki, she ran away.

Naofumi chased after her and found her being pulled out of the water by Filo. She had just tried to drown herself with the rejection from Itsuki. Naofumi offers her a chance to grow strong for Itsuki which she hesitantly accepts. Naofumi assigns her to a magic support role in the party.

Chapter Four - Custom Order
Naofumi and his party travel to the Melromarc castle. When there, he powers up his shield using materials from the castle's stockpile. He then heads to the Old Man's Shop and orders upgrades for everyone's equipment. Finally, they meet with "Nice Guy" Van Reichnott and Keel. Naofumi agrees to take care of Keel but not put her in too much danger for Raphtalia's sake. He then asks Keel and Rishia to become his slaves.

Chapter Five - Battle Advisors
Rishia and Keel immediately reject to becoming slaves. However, after hearing that it can help them power-up and that he is a nice master, they calm down and eventually accept. They get the slave crest with the only condition being that they cannot lie to Naofumi. Filo then takes Keel to level up.

The Queen introduces one of the combat advisors - Eclair Seaetto. She had been spending her time imprisoning the slavers from the Melromarc army and is the best swordswoman that is trustworthy. During training, she impressed Naofumi in her technique and skill. On the other hand, Rishia impressed Naofumi in how useless in battle she was. Filo and Keel returned making good progress with Keel's levels. The other heroes did not participate in the first day of training.

Chapter Six - Hengen Muso Style
The next day of training, Naofumi met with the Queen to meet a new combat advisor - the master of the mysterious Hengen Muso Style. They found the combat advisor excitedly praising Rishia as a prodigy. It turns out that the combat advisor was an Old Woman that Naofumi treated as the Saint of the Heavenly Fowl. During sparring, she showed Naofumi the ability to use defense-rating attacks (attacks that increase damage with the target's defense) and explained the ability to reflect the attacks. She then gave a brief overview of the Hengen Muso Style.
