The commander of the Stratus is unfazed by Alberic's pleas for time and orders the Stratus to fire on the Soara. As the Soara and Stratus fire at each other, Zuita is able to free Akari from Grad's mind control. The continued battle between the sky fortresses has severely damaged the Stratus and caused the Soara's cannon to misfire, with Alberic and the unfortunate ground forces of the Alliance caught in the misaimed blast.

Vivi and Zuita rescue Toru and the three of them agree to work together to find the others and escape the Soara.

There's only one way to save the hostage Chaika. Disgusted by his own powerlessness, Toru heads back to Goeranson Castle carrying the coffin... and at last, all of the emperor's remains are brought together in the throne room.

Tooru and party have pressed deep into the forest in search of Dominica Scoda, and end up under attack by Fayla. The one who comes to save them is Dominica Scoda herself, a dragoon cavalier who commands the most intelligent and powerful of the Fayla: a dragoon.

"This land belongs to the Neo Gaz Empire. You'll have to pay a toll." A mysterious bunch professing to work for the restoration of the Gaz Empire impedes Chaika and company's path. Among them is a girl in a yellow dress whom the others call "Princess Chaika." Akari's quick wit takes the party in under cover as a band of traveling performers, but Chaika takes a profound interest in these people from the Gaz Empire of days long past...

The town is bustling as the end of war anniversary festival is in full swing. Vivi is thrilled to have a chance to shop alone with Gillette as their team passes through on their way to stop civil disputes to the north. Meanwhile, Chaika and company are shopping for magic fuel, but all the shops are low or sold out.

In Goeranson, the capital of the Principality of Hartgen, fierce fighters from all over the world gather for a "festival." The principality's king is one of the eight heroes and the captain of the force that subjugated Emperor Gaz, the man who cut off the emperor's head himself: King Stephan Hartgen.

Arriving at Iveco, Toru realizes that something is strange about town: there are no young girls. There is also a uprising lack of magic fuel given that this region is famous for its mines of magic fuel. They learn from a shopkeeper that Duke Gavarni has been using all of the town's magic fuel to power the floating fortress Soara and that his soldiers are kidnapping the town's girls and taking them to his fortress where they are never seen again.

The party heads for a certain harbor town in search of more remains. Chaika is overjoyed to see the ocean for the first time. Upon hearing a rumor that the hero living in this town, Clay Morgan, loves to laugh, the three disguise themselves as street performers to get into his mansion, but then...?!

One month after the battle on the floating fortress Soara, Chaika is still searching for the remains of her late father, the taboo emperor, along with Toru, Akari, and Fredrica. The next owner of his remains is another of the eight heroes, Claudia Dodge.
