[It's like a pokemon battle... they lock eyes and there's the music and it's all over. It's still a bit weird for Shin, that brightening on seeing him, but he's had at least a little time to get used to it, hand lifting and fingers curling in in an uncertain half-wave as they come over.]

Ah, I'm not busy... N-nice to meet you too, Miss Kaede.

[His smile's friendly enough, even as the eyes above it aren't directly meeting hers.]

Ahaha, Rantaro's told me about you... the ultimate pianist, right?

[He's heard Komaeda go on about ultimate this and that before, although like 'hope' this and that it's something he's used to tuning out. Rantaro was really excited to learn he was the ultimate adventurer though so... it's something fairly important he guesses?]
