Trivia[]
In Liz and the Blue Bird, Kana was asked out on a date by a classmate, which became a hot topic among the flute section.
Kana borrowed Tsubomi Nakano's dress for the date where other members of her section joked by saying she wouldn't fit into it.
On the date, they visited the aquarium where Kana's date said she resembled a blowfish, in which the rest of the section found this amusing that they began calling her "Blowfish-chan".[1]
