Miyuki Sakaigawa 界川深幸

The drummer of the band GYROAXIA and a college junior studying dentistry. He used to be a kickboxer before switching over to drums to become more popular. Making use of his natural strength, he flashily engraves GYROAXIA's rhythm into everyone that hears it. Miyuki is kind to women and children, and while he looks superficial at first, he's actually rather stoic. He's among the oldest in the band and admires Nayuta, but doesn't agree with Kenta's idea of throwing away his humanity for him.
