Hanayamata 11
Close enough. There's still the weird dissonance that comes from the fact that her family speaks Japanese at home anyway, but what can you do.
The episode itself sets up the final complication before the finale, and they pull the "Kotori gambit" from
Love Live S1 where one of the cast members is going to leave the show (I know it's happened many times before, but Love Live is still in my head), and I'm not sure how I feel about this particular piece of visual symbolism. It was used in the preview last week as well, which basically "spoiled" this complication. But maybe the dramatic irony makes this episode a bit different and they can let the audience know what will happen to Hana without having to completely spell it out to them.
So if this was pure jdrama, I would expect the plane to be diverted back to Narita and for Hana to reunite with the rest of the girls before the dance contest. But since I assume that this show is better than that, I am hoping that the reunion happens a year or so later, when the girls are about to enter high school and they all suddenly see her again.
I mean, that's just as contrived as well of course, but I understand the need to make the show itself narratively fulfilling by providing a happy ending. Seeing the girls start high school also basically allows room for a sequel, assuming the manga/light novel hasn't already covered that already.
