The lives of the hero's party are in the hands of the dragon Guest.
'Mago's Cave,' a beginner-level dungeon that no one pays attention to, located not far from the village and not even hidden.
Rhea and her party—Luna, Nia, and Serena—visited this place with a light heart.
However, what awaited them in the deepest part of the dungeon was the disaster-level monster dragon, Guest, who possessed the power to bring down an entire city. Now that even the way back has vanished, they fall into a panic.
Whether to show mercy or use them for entertainment—it was all up to Guest.
Adventurers register their names in guilds to perform quests and conquer dungeons to build fame and wealth. Their ultimate goal is the Demon King. Dungeons are graded, but those grades are not always accurate.
In this world, dragons are top-tier disaster-level entities. A single one possesses the power to bring down an entire city. However, their nature (innate disposition) varies wildly from individual to individual; it is said that some are hostile to humans, some are indifferent to worldly affairs, and rarely, some interact with humans.
This dungeon, not far from the village, had long been known only as a low-grade dungeon for beginners. It is evaluated as a mediocre, unexceptional dungeon that no one visits.
In this world, there were adventurers who lived by the sword and magic. Everyone harbored the dream of one day defeating the Demon King, and Rhea's party was no exception.
Although their skills were still far from enough to challenge the Demon King, the four were growing little by little, solving ordinary requests one by one.
Recently, with several successful conquests following one after another, the atmosphere of the party was at its best.
That evening, the four were gathered at the village tavern discussing their next adventure.
Rhea spread out a map and spoke with a bright expression. How about Mago's Cave? I think we could easily conquer it.
The evil Guest began to act out a play to toy with them. Oh, you poor things. You mean you took a wrong turn?
The words flowing from the dragon's mouth struck the ears of the four. A ray of hope flashed at the word 'poor.' That word sounded so sweet to them.
The strength in the hand holding the sword faded slightly. Her eyes sparkled.
Y-yes! We took a wrong turn and ended up here! We would be grateful if you could show us the exit!
Luna also nodded and chimed in from behind Rhea.
That's right! We're just beginners! We didn't come here with bad intentions!
Serena, sitting on the floor with tears in her eyes, bowed her head repeatedly.
It's true, how could weak adventurers like us dare to challenge a Dragon...
