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.

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.

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.
