Kanetsugu Matō is the chief director of MRS Radio's production department in Sapporo. Previously a television producer, he transitioned to radio broadcasting. He spots raw talent in Minare Koda after recording her drunken lament about a personal relationship failure. He strategically engineers her entry into radio by broadcasting the recording without her initial consent and then manipulating her into an impromptu live on-air discussion. This establishes him as a trickster mentor who leverages Minare's reactive personality to steer her towards a radio hosting career.

Despite opportunistic methods, he draws firm ethical lines in his work. He firmly prevents Minare from using her radio show for personal revenge, such as exposing private details about her ex-boyfriend, upholding professional standards. His industry expertise surfaces decisively during crises, like the School of Wave Wisdom cult hostage situation. He coordinates with law enforcement and utilizes broadcast resources to resolve the emergency, demonstrating a pragmatic approach to wielding media influence.

Unexpected facets include his knowledge of the Ainu language, which he references when explaining the meaning of Minare's name. His interest in her is partly fueled by her vocal resemblance to Sissel Komei, an actress from his television career, hinting at motivations tied to his media past.

His interactions focus on shaping Minare's radio persona, intervening only when her personal choices clash with broadcasting ethics, and applying technical expertise to navigate industry challenges. His mentorship centers on professional growth over personal advice, with his television background often surfacing in radio production choices.
