Minoru Kagamari, a 23-year-old first-year editor at Shueisha in 2006, serves as Rohan Kishibe's manga editor. Married with no children, he has an average build, a slightly chubby face, small eyes, and stylized sideburns. His distinctive attire features a crosshatch-patterned long-sleeved coat and pants, an upturned collar with light frilled trims, and a matching beret adorned with small circular beads. He consistently wears a watch on his left wrist. Courteous yet inexperienced in handling Rohan, Minoru respects the mangaka’s work but lacks broader cultural awareness—mistaking the artist De Staël for a music band, much to Rohan’s surprise. He arrives six minutes early to a meeting, unaware this breaches etiquette, and apologizes when corrected. Hearing Rohan explain his bankruptcy after purchasing six mountains for yokai research, Minoru silently questions the mangaka’s stability while avoiding direct comment. When autograph seekers Tamami Kobayashi and Akira Otoishi interrupt the meeting, Minoru attempts to dismiss them, citing Rohan’s schedule. Rohan rebukes him, declaring he is not a "slow mangaka," and signs the autographs. Minoru never reappears after this encounter; his replacement by Kyoka Izumi implies he stepped down from Rohan’s account, likely due to discomfort with Rohan’s eccentric behavior and paranormal interests. His involvement is confined solely to the "Mutsu-kabe Hill" story.
