"Our regrets make us stronger."

After hearing of a village in the East that's being ravaged by an epidemic, Naofumi and his party head there to deliver medicine. The epidemic was caused by the corpse of a dragon that had been killed a month before and left there to rot. Naofumi's party accepts a job request to clean the corpse and head to the mountains where it lies.
