The current quest is to make Jiffon Island's harvest festival a success, but the festival can't be held because some orcs that strayed onto the island have taken over all of the Buffo that are traditionally offered as sacrifices. On top of that, the increasing number of orcs threatens the islanders' very lives. With the festival date only 11 days away, Yotsuya begins leveling up to raise his rank so he can help fight them, and his job changes to Blacksmith.

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.

The islanders have sent the women and children away on a boat to protect them from the upcoming battle, but the orcs find and target them. Shindou and Cantil move to stop them, but in the midst of the fight, the earth begins to shake violently as the volcano on the island erupts. Pandemonium breaks loose as volcanic bombs rain down on the island... but this is only the prologue to a much greater disaster.

The threat of the orcs has passed, but a dragon hanging out in the caldera brings a new threat to the island. It appears to be sucking the life force out of the islanders to store up energy, but it would be suicidal to try to attack it head-on. While fleeing, Yotsuya and Torii stop to help one islander...

Yotsuya's party manages to escape the village, and then they encounter a large group of people. They turn out to be the ones who had been run out of the village under the pretext of going on the Journey of Hope to find the so-called New Eden. The party accompanies the villagers in their hurried search for a new permanent residence, even as monsters close in on them...

After joining up with the villagers who had left on the Journey of Hope, Yotsuya's party starts to notice that everyone is complaining of feeling tired, reminding them of what happened at Jiffon Island. When the group is attacked by monsters, a surprising figure from their past shows up and saves them. He also tells them that he's been pursuing Dragon Bishops, that their evil influence is spreading, and that he knows why all the local monsters are so much stronger than the norm.

Glenda has figured out the identity of the Dragon Bishop who's been secretly at work in the area. With her identity exposed, the Dragon Bishop confesses that she was behind everything that's happened since they began the current quest, and explains that she approached Yotsuya's party while searching for a hidden village in order to complete her ritual. Thus begins the battle between the Dragon Bishop and the party of heroes.
