Yotsuya's plan to rescue the heretics is successful, as is his vengeance on Kamilto for killing Kahvel's subordinate. He and Tokitate head to Radodorbo with the heretics while Shindou and Hakozaki travel separately in hopes of finding cargo bound for Radodorbo. Along the way, Tokitate becomes invested in what she perceives as a budding relationship between Yotsuya and Kahvel and tries to initiate events to bring them together.

The boy Yotsuya saved in the Chinese restaurant, Torii Keita, turns out to be the fifth player. They're sent to the alternate world again, and after receiving the fifth quest, they head for Cortonel to track down some leads. There they find Kahvel, who is now a mother. The party is shocked to learn that 15 years have passed since their fourth quest, but that isn't the only thing that's changed in this world.

After becoming a Blacksmith, Yotsuya developed two new tactical weapons to use against the orcs: the Storc for close-range combat and the Orc Eater for shooting from a distance. Although they successfully use these to fight off the orcs attacking the stronghold, the orcs learn how to throw projectiles by observing the long-range weapon. Both the humans and the orcs have suffered substantial damages as the battle enters its final stages.

Jiffon Island has taken severe damage from a series of natural disasters. Some of the survivors have taken shelter in the castle. The Orc Queen, after barely surviving the battle, reaches the boat that was carrying the human children to safety. Giving up hope for the island as it's ravaged by one disaster after another, she tries to escape to a new land with the orc children, but finds herself facing Shindou and the other human fighters first.
