where does kaede say that?
A friend of mine believes she says something like あ、そうそう…私の名前は赤松楓。 超高校級のピアニストなんだ。よろしくね。
In this image. Very, veeerry rough translation but I believe thats the gist!
A couple of other translators (rather, the two well known DR translators i’ve reblogged from recently) here on tumblr believe it says Pianist as well.
