A bit of a lesser episode because it had some unnecessary stereotypes: the pool episode and the tsundere sister, things that have been done millions of times before. But yeah, I guess that in the context of this series it still had its fresh elements.
That swimsuit was a bit too much, especially considering how Yamamoto had no idea about Tsuchida’s reaction to it. It’s a good thing that she still lives with her parents, because I really don’t think that she could take care of herself on her own… But overall, what set this episode apart was the focus on siblings. And when Tsuchida’s sister wasn’t acting like a shallow tsundere, she was surprisingly down to earth and interesting. And the synchronized swimming part was hilarious.
The thing about this series is that the adults all had lives on high school before they started to work at the kindergarten, which were vastly different compared to what you’d see in high school series, in which kids tend to segue from one to the other quite naturally. Tsuchidahas been characterized pretty well throughout the past six episode, however he remains rather annoying when he keeps ogling at Yamamoto.
