北宇治高校吹奏楽部、部長・副部長・会計の幹部三人組。

原作だと香織→あすか←晴香って感じで香織・晴香の絡みはあまり無いですが、アニメは二人が仲良しで三角関係感あって良いですね。
でも７話の晴香→あすか描写は少し削られて残念だったけどその分“吹部のマドンナ”がいいところ見せたのでオッケーです

The trio of Kitauji High concert band president, vice-president and treasurer.

Even though the feel in the source material is "Kaori->Asuka<-Haruka" and there are hardly any Kaori-Haruka moments, I think it's good that those two get along so well in the anime that there's a feeling of a love triangle.
Though it's a pity that episode 7 whittled down the portrayal of "Haruka->Asuka", "the Madonna of the Band" put her best foot forward and made up for it, so it's all good.

PS: got to #248 in the daily ranking. Thank you very much!
