Ruka is at least aware of the idea of qi and she makes a noise of understanding. It's really a pretty song; she closes her eyes, humming as she tries to recall the melody. While she doesn't remember it with perfect clarity (no pun intended), she can remember most of it and resolves to try recreating it on the piano later.

"I'm wishing I'd learned to play something more portable now. The piano is huge and you can't bring it around with you. But I think I used to sing too." She'd been the Vocal Organ during the Rogetsu Kagura/Rite of Descent, after all, but it had been a long, long time ago when a child's singing voice was generally just 'cute' and it didn't matter if it was beautiful.
