Prologue
Naofumi accidentally sleeps in after the hard-fought revolution to defeat the corrupt Heavenly Emperor in Q'ten Lo. As he wakes up, he is greeted by Filo and Raph-chan who then lead him to Raphtalia.

Chapter 1: Treasure Hunting
While Q'ten Lo is still in unrest due to the change in leadership, Raphtalia is finally able to rebuild relations with other countries. Even though it has only been a few days, Raphtalia has already started working on a treaty of friendship with Siltvelt. Bored in the castle, Naofumi, Raphtalia, Filo, and Raph-chan decide to check out Raphtalia's father's room and have a "treasure hunt". As they search, Naofumi and Raphtalia's discussion changes towards Naofumi's parent's which leave him a little upset. However, Filo interrupts the two as she finds a map of the castle with an "X" marked on it. Intrigued, they head out to find it.

Arriving at the location marked on the map, they find wooden box with a key and another map inside. Naofumi recognizes this as a lengthy "errand mission" from online games but he is eventually convinced to continue the search and they find map after map. As they continue their search, they realize that this map-hiding and treasure hunt has been going on for generations. Continuing the expedition through the secret passages, they end up in a stone chamber with an inscription only Raphtalia can read. On the inscription is description of Heavenly Emperor techniques as well as the role of the "Pacifier of Spirit Implements."

Continuing the expedition, they head by Q'ten Lo's Dragon Hourglass. It seems like this location is a dead end. However, they find a picture crystal with a picture of Raphtalia's Father and Raphtalia's Mother together. Naofumi pays his respect to Raphtalia's parents then then Naofumi, Raphtalia and Filo also have their picture taken on the crystal.

Chapter 2: Hakuko Siblings' Homecoming
A few days later, the treaty with Siltvelt had been signed and Q'ten Lo finally seems to be resting. Naofumi and Raphtalia train while testing Raphtalia's new Heavenly Emperor Abilities while Atla and Fohl stop by. Recognizing that she is being left behind in combat prowess, Atla challenges Raphtalia to a spar. Fohl also challenges Filo to a fight but is quickly defeated. After a long battle, Raphtalia ends up beating Atla.

After the fight, the group decides to go to Siltvelt to train and to see the Hakuko siblings' birthplace. They arrive at the siblings' large old house and the group explores the residence. The house has been stripped in the past to pay for Atla and her mother's medicine but Fohl dreams of restoring back to its former glory. They eventually find a Hakuko ceremonial dress that Fohl convinces Atla to try on. Atla proudly shows off the dress to Naofumi but is disappointed by Naofumi's response.

In the meantime, Fohl finishes his traditional Siltveltian meal and everyone digs in. Seeing that Fohl is disappointed at not completely remembering one of his mother's dishes, Naofumi tries to recreate it from Fohl's description. It turns out that the secret is seasons from their mother's home country of Melromarc.

The next morning a messenger arrives and let's Naofumi's group know that a Seven Star Hero had arrived to Siltvelt. They head out to meet the hero.

Chapter 3: The Shield Hero's Parade
Arriving in Siltvelt, Naofumi and his party prepare to meet the Claw Hero who had apparently been away training. However, meeting up with Werner and the Genmu Representative, it turns out that the Vassal Claw Hero is still several days travel away. They then mention that the Siltvelt people have been anxious to see their revered Shield Hero and asks Naofumi to make a public appearance. Raphtalia - possible as revenge for Naofumi making her do parades in Q'ten Lo - convinces everyone that having parades is a great idea. The Genmu Representative also schemes to have the other Legendary Heroes secretly help the parades so that their reputation in Siltvelt will be improved.

Returning to the Village, Naofumi asks Ren and Itsuki about helping out with the parades. To his annoyance, they both agree. They have the first parade in Siltvelt's Castle Town with nothing going wrong. The group goes teleports back to Q'ten Lo and enjoy the hot springs there. After washing up and being interrupted by Sadeena and Shildina in the men's bath, Naofumi goes to introduce Ruftmilia and Shildina to the members of his village.

To Naofumi's boredom, he continues doing the parades throughout Siltvelt. Eventually, they reach a town with a burial mount similar to the ones that sealed the Tyrant Rex or the Orochi. Asking about the history, it seems that it held a nine-tailed fox that tried to take over Siltvelt. However, someone from Q'ten Lo - possibly Raphtalia's Ancestor - sealed up the creature. Investigating the mound they found that the seal had been broken and the mound was empty. However, they continued their parades throughout Siltvelt.

Chapter 4: The Nine-Tailed Fox
After days of parades, it looked like the trust in the Siltvelt people had been restored. Also, the Seven Star Claw Hero was due to arrive at any time from Faubrey. As the impressive fighter enters, the two heroes start to talk. However, Naofumi is suspicious of the man since he did not help during the Spirit Tortoise catastrophe or any time he was called. The hero, Rhubaldt, apologizes and everything seems normal at first.

However, as soon as Naofumi asks for the Seven Star Claw power-up method, Rhubaldt's demeanour changes. He deflects and asks for Naofumi's power-up methods instead. When Naofumi declines, Rhubaldt starts calling the Shield Hero weak and possibly an imposter. As the conversation deteriorates, Raphtalia notices that Rhubaldt is using an advanced illusion on himself and points it out to everyone. She even finds out that the person claiming to be Rhubaldt doesn't even have the Seven Star Claw. At their identity being revealed, the false hero drops their illusion and she rushes to attack Raphtalia.

Naofumi deduces that this false hero is the nine-tailed fox which was sealed in the burial ground in Siltvelt. Naofumi's party fought against the illusion user, however she had incredible speed and combat abilities. Eventually, as her odds in battle get worse, the fox woman transforms into her nine-tailed fox form and runs out of the castle.

Epilogue: Suspicion of the Seven-Star Heroes
After the fox woman left, Naofumi declares his suspicion for the seven-star heroes. He confirms with the others that the real wielder of the Vassal Claw weapon is still alive. It seems that this fox woman had been blessed by a Vassal Hero so Naofumi prepares for another encounter with the woman.
