Miyuki is a third-year taking up Dentistry and the drummer of the band GYROAXIA.

Being amongst the oldest in GYROAXIA, he's friendly towards children and women, and is actually quite stoic despite his superficial looks. He's significantly more hostile towards Kenta Satozuka, strongly disagreeing with his management policies. He also admires Nayuta Asahi, but doesn't agree with Kenta's idea of throwing his humanity away for him.

Miyuki was a kickboxer before switching over to drums to get more popular. Making use of his natural strength, he engraves GYROAXIA's rhythm to anyone who hears in a flashy manner.
