Itsuki, Hayato, and their entourage of lovely ladies have finally arrived in the royal capital. Their mission? Secure a Miracle Drug to restore party member Chris's injured eye. Before they do, Istuki and the gang decide to do some sightseeing and pay a visit to the grand cathedral, a popular tourist attraction. There, Itsuki is shocked to find that this cathedral's nuns are more interested in partying than praying! Later, when he and Hayato attend the auction for the Miracle Drug, they encounter a mysterious woman and learn they've got some unexpected competition.
