Kazuyoshi Kunugi is a supporting character introduced during the news network expansion arc of the story. He is a seasoned and highly talented news producer who comes to play a key role in the operations of Trillion TV, the online television service launched by the protagonists.

Kunugi's professional background is that of a star producer who originally worked at a major traditional television station. However, he grew disillusioned with the industry's practices and made a principled move to a production company. This decision was driven by his firm belief that failing to report the truth is an offense worthy of the death of journalism. Despite his talent and experience, at the time of his introduction, he is working at Kawara TV, a second-rate and uninspired station where his abilities are underutilized.

In terms of personality, Kunugi is a battle-hardened veteran who carries both light and darkness within him. He is described as a very passionate and down-to-earth person, but he is not purely righteous or straightforward. Instead, he possesses a notable cynicism and acerbic wit, always seeing the implications and angles behind every situation, which makes him razor-sharp in his field. He is pragmatic, raw, and has a certain grittiness to his demeanor, often coming across as a "scumbag" in his own estimation due to his pragmatic focus on ratings over idealism. The character also frequently participates in the story's comedic moments, balancing his serious nature with a more humorous side.

Kunugi's primary motivation is rooted in his journalistic integrity. He values the pursuit and reporting of truth, which is why he left the environment of a major network. This dedication to journalism is a core part of his identity. His role in the story is that of a key power player recruited by the protagonist, Haru, to build a legitimate and impactful news division for Trillion TV. Haru successfully seduces Kunugi to his cause by appealing to this very nature, recognizing that his expertise is essential for giving the new network credibility. Once on board, he functions as a strategic operator and news savant, helping to navigate the ethical and practical challenges of running a news organization.

His most significant relationship is with his colleague, Akari Shirotora. Their dynamic forms a powerful and complementary pair. Whereas Akari is relentlessly earnest, idealistic, and seemingly incapable of deceit, Kunugi is cynical and pragmatic. He recognizes her value as his biggest asset and often tries to protect her pure image from the uglier sides of the business, a decision that carries both chauvinistic and practical components. Despite his tsundere-like protestations, they deeply respect each other and are a formidable team. He also develops a strong working relationship with the main characters, Haru and Gaku. With Haru, he finds a kindred spirit in the sense that they both are willing to play the game of business—Haru for money and Kunugi for ratings—and they form a mutually beneficial partnership based on this shared understanding. He also utilizes Gaku's technical genius, for instance, by having him use AI to verify user-submitted news videos.

Kunugi demonstrates significant professional development through his decision to join the upstart Trillion TV, a move that allows him to practice journalism with more freedom than he had at his old, stagnating station. His character is tested in storylines that challenge his journalistic ethics, such as when Trillion News must decide whether to report on a story about a major sponsor's exploding phone, forcing him to weigh his principles against the survival of the network.

His notable abilities lie in his sharp, analytical mind and his deep understanding of the news industry. He is a top-tier producer who can look past the obvious and assess situations with a critical eye. His experience and savviness make him an elite talent, and his ability to recognize and cultivate talent like Akari Shirotora further demonstrates his competence in the media business.
