Considering Kidou Yuuto (it's so weird using his first name) would be going through trying everything, he probably took a crack at picking up an instrument at one point, if you'd like these two to have some starting CR.

He's also a decent enough singer (canon | and this because it cracks me up (he's the deeper voice)) so maybe that could be an option. Who knows?

Okay I admit I'm just fascinated by this character and have never heard of him or his canon before. A+ pun on trumpet swan.
