The Adventurer Guild begins their operation to clear the monsters from the mines. The mission goes smoothly until they discover a large nest of goblins deep inside. The adventurers then launch a coordinated attack against the goblins and despite the enemies being in a larger number than expected, they are defeated without casualties, with Ryoma and his slimes having an important role. Once he returns home, Ryoma decides that he can't indulge further on the Jamil family's hospitality and expresses his desire to live independently from them.
