Choke Week day 4 - 響け！ユーフォニアム (姫神 琴子) (Pixiv Fanbox)

Kotoko chan is a flutist and section leader from Sound Euphonium. Despite being a minor character, she tottaly looks like a loli and is the boss of brass band flute section. I said on Twitter I wanted to post some flutist character from this anime. I thought of Nozomi, but I don't like her. She is so fake.
