I Got Caught Up In a Hero Summons, but the Other World was at Peace Vol 6

From the Seven Seas Entertainment edition

TRIP-CEPTION! On a whim, Alice whisked Kaito off to an entirely new country, Alcresia! For what purpose? Food, of course! But after a good time gambling and an impressive beginner’s luck streak, Kaito’s prizes might prove hard to take home. Before they can be on their way back to Symphonia, a messenger appears–the Emperor of Alcresia has summoned him to the castle. What sort of trouble has Alice gotten Kaito into?
