Ryoma, the boy from another world, takes the opportunity to revisit the Jamil estate, where his fellow merchants Serge and Pioro and a friend's unexpected marriage are all converging. Ryoma's happy to help the young lovebirds--provided he can tear himself away from developing new uses for his slimes and expanding his business! There's more familiar faces and laid-back scenes to come as well, of course, and a stalwart (if dubiously attained...) new ally too!
