It’s a testament to this show’s quality of characters that I can utterly disagree with Sei’s mom’s position but still love her to death simply because she’s so hilarious and awesome. As worried as she is that her son is being corrupted by island yokels, she’s the one doing childish things like sticking talismans on his door and rains down blows upon anyone who looks at her the wrong way. Mostly though, I can forgive her hypocrisy because she just plain misses her son.
As the gang (mostly Miwa) goes through an infinite cycle of trashing, cleaning, then trashing his house, it looks like Sei’s mom may get her way by sheer force of her maternal power, but Sei, strengthened by his time on the island, isn’t going to surrender so easily.
When her husband breaks out albums from when he was on the island, her position starts to crumble, and when the gang mails him the results of his calligraphy tutoring, she loses the moral high ground altogether, which was built upon an ignorance about what exactly he was doing there anyway.
Seishuu has had a track record of acting impulsively, and be it punching an old man or accidentally buying corn soup on a hot summer day, it often results in painful experiences. But that same impulsiveness allowed him to act upon sudden flashes of inspiration and break out of his conservative style.
Thus, it’s more about tempering and balancing that impulsivity rather than rooting it out. The best environment for that has been and shall continue to be the island, which he already considers “home.” And even for the gang, home doesn’t feel the same anymore without Sensei.
When Sei arrives back on the island and the village chief is a no-show, he leaves the airport, wanders, and immediately gets in trouble. But then Naru’s grandpa offers him a ride on his tractor, and he sees the gorgeous ocean that gramps says is “nothing special”, and he’s lockedback into an Island state of mind, where “nothing special” is the best.
As Seishuu has taught the islanders about calligraphy and entertained them with his cosmopolitan shut-in ways, they’ve taught him that there’s nothing quite like a life lived with cheer surrounded by people you care about. It’s fun, but it’s also good for the soul, and good for his artistry.
Once a surly, willful wretch that was first exiled to the island against his will, Seishuu’s now a little more mature and content. His eyes are wide open to what the world has to offer, and how best to contribute.
