As expected, the final Hibike! Euphonium 2 of the season is an epilogue; it even has ‘epilogue’ in the episode title. The third years are given a proper sendoff with lovely musical performances accompanied by montages of both this season and the last.
Yoko and Natsuki take up the mantle of new president and vice president, and the former can hear the loss of the third years.

So can Taki-sensei, who acknowledges that every year school bands essentially take a big step back due to the outgoing talent. That experience must be replaced with the remaining members plus the rawer talent of incoming first years.
The same band that made it to the Nationals no longer exists. The one that intends to make it back will be an entirely new one: new leadership, new composition, new style.
Since Kumiko and Reina are first-years, they have not one but two more years to achieve their goal of National Gold. And they seem as optimistic and determined as ever to get there, despite their bronze finish this year and the loss of so much talent.
Their problems going forward are the same problems all school bands face, and secondary problems — such as Yoko and Natsuki clashing — are sure to crop up.
The key (no pun intended), I suppose, is to avoid really big dustups such as the ones that took place before Kumiko and Reina arrived at Kitauji; the kind of conflicts that actually hindered the band’s performance, and the wounds of which have now all but faded.
And so we get a nice, long, heartfelt goodbye as all the seniors play for their juniors, then vice versa. There’s a commencement ceremony, where the goodbye hugs and wishes continue. And throughout this epilogue, Kumiko is sad and upset, all because Asuka is leaving.

She runs all over the school grounds, increasingly desperate to find her. As usual, Asuka is trying to avoid “these kind of things”, but Kumiko won’t let her escape her, or her true feelings. Kumiko thinks she might have hated Asuka at first – but now all she feels is love. Romantic love? Perhaps it hews close to that, just as you could read her feelings towards Reina on top of that mountain last season.
But whatever specific kind of love it is, she’s got it, when she didn’t have it before. Asuka is someone she let into her life and personality, while continuing to hold back from Shuu (poor Shuu). Asuka is someone leaving, whom she doesn’t want to go. She has eyes for no third-year but Asuka.
And now she’s the chief euph, and her bandmates even remark how she sounds like Asuka. Like Mamiko, Asuka has helped shape and progress Kumiko’s musical development and identity. I’m unsure if there will be a Euph 3, but there’s plenty of great material to continue with.
