In an attempt to be fair, not equal, Miku cites a technicality in the Campfire Legend: the key is not dancing with Fuutarou, but holding his hand at the finale. Since Fuutarou has two hands, she proposes she and Ichika both be holding them at the proper time. Unfortunately Ichika was coughing and couldn’t hear what Miku proposed, and Miku can’t bring herself to repeat it.
That brings us to the more pressing matter: Itsuki has apparently vanished. Despite fading fast due to catching Raiha’s cold (getting wet last night couldn’t have helped) Fuutarou coordinates a search, bringing a masked Ichika (who apparently caught Raiha’s cold through him) along with him. However, whenever a quint is masked or their face otherwise concealed, one has to suspect something is up. Also, the normally lilac-topped “Ichika’s” hair looked a bit too deep red.
Sure enough, Fuutarou catches on that “Ichika” is really Itsuki in disguise, because back when they were skiing she called him “Uesugi-kun” instead of “Fuutarou-kun.”He waits until the two of them are up in a chair lift to say so.
Turns out Itsuki got separated and lost due to her poor eyesight. That begs the question Why not contacts? Nino wears ’em, and her vision is thoroughly impaired. In any case, Itsuki was apparently testing Fuutarou to see if he’d be able to tell them apart…because their father can’t, I guess?
Itsuki’s whole thing is a bit of a head-scratcher, so let’s move on, shall we? Fuutarou reaches his limit, and he reaches the point where he can’t seem to get rid of the five quints, when at the start they were running away from him.
He somewhat coldly asks what purpose would be served by any of them staying with him, and the head teacher declares the room where he’s resting to be out-of-bounds, which all but ensures they’ll find a way to break in and be with him.
This is all happening during the campfire, which Nino stands beside all alone, dancing with no one. Fuutarou took her a aside earlier to tell her “Kintarou” couldn’t make it, which seems like a cowardly move on his part, especially after she explicitly asks if she can trust him. I know he’s trying to spare her feelings, but I reckon Nino would prefer honesty over fiction.
Meanwhile, Miku and Ichika have a nice sisterly moment where Miku does what Fuutarou couldn’t with Nino: she’s forthright and honest. She likes Fuutarou, so she’s going to do what she wants going forward, while accepting that the others can do what they wish too. Even Yotsuba has a rare subdued moment where she finds Fuutarou’s well-worn camp guide and kicks herself for pushing him so hard he got sick, when again it was likely Raiha who got him sick.
As the campfire (and, incidentally, the show) builds towards its finale, the five sisters are surprised to find all of them breaking into Fuutarou’s room at the same time, even going for the light switch in unison. They also each manage to grab one of his fingers the moment the campfire ends.
Flash forward to the future, when Raiha is now a high schooler, the morning of the day her brother is getting married. The bride we see could be any one of the quints we know, and indeed is depicted as more of an amalgam of the five than any individual quint.
It’s therefore an incomplete future; he may one day have to choose one and their identity may be revealed, but this season is not interested in answering the question of who quite yet. There’s more story to be told! Back at school, the five sisters are finally on the same page about studying with him, with the final holdout Nino tsundere-ly relenting to the majority. Ichika’s decision to quit or change schools for her acting career is left up in the air.
When a recovered Fuutarou warns them he’ll be working them hard in order to get their test scores up, they’re all unnerved and run away from him together, the way they used to when they first met him. The difference is, they’ll be back, for his tutoring, for his friendship, and maybe for more. They can’t not…after all, they were all held hands at the end of that campfire!
In the final ranking of the Quintuplets…Wait, what’s this? They all scored 100? It’s a five-way tie! What are the odds? Looks like the argument of “Who is the Best Quint?” will have to be resolved in Season 2, coming Winter 2021…
