Kugimiya Masami is one of Tatara's rivals and occasional training partners in the dance world. They attend the same dancing school. His style of dancing can be described as "elegant, strict, and traditional", and his partner is Idogawa Tamie. He and Idogawa had taken leave from dance competitions for a year before their comeback around the same time as the beginning of Fujita's breakthrough due to an unspecified injury.
Even though he's a professional athlete, he smokes occasionally. Kugimiya wears driving glasses, and is shown to be protective of his partner. He has two nephews, who often come to watch his performances.
