Kyoka Izumi works as an editor at Shueisha, specifically assigned to manage manga artist Rohan Kishibe's serialized works for Weekly Shonen Jump, including *Pink Dark Boy*, and to suggest new story ideas. Though she initially aspired to work in fashion magazines, she was placed in the manga editorial department. Her family background involves a father who worked at a trading company and a mother with a television background, contributing to her overconfident yet sheltered upbringing. Her father passed away when she was young, leaving her mother as her primary caregiver. Personality-wise, Kyoka blends naivety, perseverance, and overconfidence. Her easy-going demeanor often conceals a mildly arrogant attitude, sometimes resulting in unintentional rudeness, such as casually dismissing Rohan's ideas while pushing her own during story discussions. Highly ambitious, she frequently uses the word "aspiration." Her upper-class background fuels interests like acquiring property in the Millionaire Village for financial gain. Despite graduating from a prestigious university, she lacks sharp critical thinking and secretly researches topics to avoid appearing uninformed. Her fashion sense favors cute, Lolita-style clothing while avoiding flashy or branded items. She also shows altruism, like helping an injured bird at the Millionaire Village and seeking to support her boyfriend, Taro Hirai, who faces mental health challenges after a car accident. Her notable appearance occurs in the "Millionaire Village" story. Learning about a village where residents mysteriously gain wealth, she decides to purchase a villa there and invites Rohan, hoping it inspires his next manga. During the visit, she disregards Rohan's warnings about supernatural etiquette tests, violating rules concerning seating positions, tatami mats, and tea-drinking customs. This triggers a curse manifesting as false reports of her mother and fiancé's deaths (later revealed as minor accidents in some adaptations). Rohan uses his Stand ability to reverse the effects, saving her from a heart attack. The incident highlights her naivety and ambition-driven risk-taking. Expanded media, like the live-action drama, elaborates on her ownership of a dog named Maron and her relationship with IT worker and photographer Taro Hirai, whom she admired since high school. Her motivation to buy the Millionaire Village villa partly stems from wanting to help Taro recover his interests post-accident. A timeline details her birth in 1996, early career struggles at Shueisha, and her assignment to Rohan after a previous editor resigned due to the artist's difficult behavior. Daily routines, including skincare regimens and walks with Maron, are also depicted. Later manga chapters ("Hot Summer Martha," "Drip Painting Style") feature her professionally. She expresses concerns about copyright issues for Rohan's work and congratulates him on successful publications. These appearances reinforce her role as a diligent editor navigating Rohan's eccentricities, maintaining her characteristic blend of ambition and occasional incompetence. Her development across media consistently portrays her as a well-meaning but flawed individual whose personal and professional endeavors drive both conflict and camaraderie with Rohan.
