Ryouma has quietly had a musical side job since he's been here working the traditional music scene, so he's not going to be shy about performing in front of this crowd even if this is way higher stakes and fancier than he's used to!

He'll change out of his Western-style suit and wear something more traditional to be a little more thematically appropriate. Since it's a special occasion and all, he'll keep things lively, and he's basically just going to show off (something like this) because he's been playing it since he was a kid so he might as well! He sings a little too, but he's not trained a singer; he's just got a lot of enthusiastic folk songs that he knows! Attempts are made.
