Handyman Saitou in Another World, Vol. 5

Upon returning to town, the party hears rumor of a new treasure--the Golden Armor of the headless knight Dullahan. If they can get their hands on that armor and sell it, they'll be rich! But during their descent, the party gets separated from Raelza... They agreed to abandon her and return to town, but can the party really leave her to die in the caves? If not, they have to hurry--because another government-certified party just showed up vying for the treasure!
