I wish that the tropical island and funny-animal plot elements had been cut entirely rather than minimized to their stature in this adaptation. None of them seem to add anything to the narrative, and cutting them would have allowed for a stronger depiction of the curiously healthy traditional shōtengai. However, even elements of that depiction are quite weak, particularly episode 6, an “idiot ball” sitcom plot.
Relegating the finished exotic side plot to an accompanying short allows Yamada to focus on Tamako and her friends, Kanna being particularly amusing here. The long-awaited romantic resolution, albeit predictable, is a welcome break from crappier moekko shows where the very possibility of romance is excluded.
In referencing butt mochi, it establishes itself as an appendage to the film and not a sequel to the series. As expected, the characters of the fictional southern island—a less cannibalistic but equally exoticizing Rokovoko à la Moby Dick (1851)—have no lives beyond what is relevant to their tenuous connection to Japan.
