Dariel learns that Lux Village once flourished due to a nearby mine. When the demons took it, they condemned the village to a slow death. As the mine is Dariel’s old workplace, he decides to visit it to see if there’s anything he can do for his new home.

Bashbarza is in a rage after being reprimanded by the Demon King for losing the mythril mine. Meanwhile, in Lux Village, the mood is a celebratory one. Dariel runs into an old coworker and sees an opportunity to prevent conflict between humans and demons.

Dariel and the others rush to the Mythril Mine on a rescue mission, but the Magical Fire Beast, Salamandra appears in their path. Dariel presses ahead with their rescue efforts, but Bashbarza, who has obtained tremendous power, has other ideas.
