Sadaharu Kamo

Sadaharu Kamo is a supporting character in More Than a Married Couple, But Not Lovers (Fuufu Ijou, Koibito Miman). He is the best friend (and initially the only close friend) of the protagonist Jirō Yakuin, serving as the one person Jirō opens up to despite his introverted personality.

Sadaharu is depicted as a mild-mannered, slightly eccentric otaku who loves manga, anime, video games, and 2D girls (preferring them over real-life romance due to his bad luck with women). He often provides comic relief by pointing out tropes from anime/manga in real-life situations, breaking the fourth wall at times, and offering support or advice to Jirō—sometimes pushing him forward in his complicated "marriage practical" scenario.

He's generally a good-hearted guy who goes out of his way to help his friend, even if he's socially awkward himself. In the anime, he's voiced by Sho Nogami (Japanese) and Derick Snow (English dub).
