This episode illustrates how Seishuu, formerly the outsider, is steadily becoming “one of the gang,” someone both the adults and children of the village can trust and rely on. Rather than shun a city slicker, they welcomed him warmly, and Seishuu has settled nicely into their flow.
While he’s periodically pacing around paper and slowly having all thought replaced by konomon, the girls (Naru, Tama, and Miwa) decide to enlist his help with their calligraphy assignment, and he takes to teaching like a fish to water, giving instruction and not suffering (or trying not to suffer) any dalliance.
I particularly like how Miwa describes Seishuu’s present style as “fuzzy” and “showy,” and that Seishuu won’t teach it to them until it’s acknowledged; i.e. won grand prize. Naturally, he goes a bit far in vocalizing his passion for the art, and the girls’ focus pivots from their calligraphy to the fact that calligraphy seems to be all Sensei thinks or cares about.
One would guess that Seishuu doesn’t have a girlfriend because he feels any time or energy spent on one would be time and energy taken from the calligraphy, which would be disastrous. But the fact is, he’s already spending a lot of time and energy with the girls and other villagers, and that energy is helping his work evolve and improve.
When Seishuu is asked to chaperone the kids on a trip to the beach. It’s a beach black rocks rather than soft sand. While he has trouble with his footing on the slippery rocks, one can say he’s definitely found his footing in the village. Having to watch the kids and keep them from killing themselves makes him realize how much he’s come to care for them.
