I Was a Bottom-Tier Bureaucrat for 1,500 Years, and the Demon King Made Me a Minister, Vol. 2 (manga)

Beelzebub has at long last grown into her new position as minister. From auditing the territories of hostile aristocrats to renovating the cafeteria, she can handle it all. With things going so well, surely no one would object if she were to plan an office trip-er…a training excursion to a hot spring region to “sample” the local specialties, would they?
