Misao Kuba is a 25-year-old male twin employed by Kanou. He possesses black hair, blue eyes, stands 1.84 meters tall, weighs 74 kilograms, and has blood type AB.

Compared to his older twin brother Homare, Misao exhibits minimal feelings and emotions. He displays little interest in others, including Homare, and maintains a general disinterest in the central relationship between Kanou and Ayase. The twins share an indistinguishable physical appearance.

Misao finds particular enjoyment in food. His relationship with Homare remains professional, defined solely by their shared work for Kanou, though their specific duties are unspecified. One source suggests an attraction toward Ayase, but this detail lacks corroboration elsewhere.

Across all official media, Misao's character presents no significant background story or development. His portrayal remains consistently that of an emotionally detached and secondary figure throughout the series.
