Kyōka Izumi is the editor assigned to Rohan Kishibe at Shueisha, the publisher of Weekly Shonen Jump. She is responsible for managing his erratic schedule and ensuring his manga is submitted on time. In the story At a Confessional, she accompanies Rohan on a trip to Venice, where he is scheduled to speak at a university, and she becomes involved in the mysterious events that unfold around a cursed confession heard in a church.

Her background is that of a professional editor working for a major publishing company. She is characterized by a cheerful, persistent, and somewhat naive demeanor, which stands in sharp contrast to Rohan’s cynical and eccentric nature. She is also notably focused on social status and proper etiquette, a trait that becomes relevant in other storylines such as Millionaire Village. Despite lacking any supernatural abilities, her determination and social intuition sometimes provide Rohan with helpful insights or leverage when dealing with unusual situations.

Her primary motivation is to fulfill her professional duties: keeping Rohan on deadline and managing his unpredictable behavior. She also harbors personal ambitions and an interest in status, which occasionally drives her decisions. In the live-action adaptation, her character is expanded with additional personal connections, including a fiancé who appears in a separate episode.

Her key relationship is with Rohan Kishibe, her author. This relationship is a complex dynamic of professional handler and creative foil. She is often frustrated by his artistic whims and disregard for deadlines, yet she remains loyal and persistent in her role. In the live-action series, she transitions from a minor background character in the original manga to a primary supporting lead, becoming a frequent companion in his investigations of the supernatural.

Her role in At a Confessional is to provide a grounding presence as Rohan immerses himself in the bizarre confession. She reminds him of practical concerns, such as their flight to Venice, and later becomes caught up in the unfolding curse alongside him. Her observations and actions contribute to the resolution of the story, reflecting her growth from a mere handler into a participant in Rohan’s strange adventures.

Notable abilities are limited to her professional skills and personal qualities. She does not possess a Stand or supernatural power. Her strengths lie in her perseverance, her social awareness, and her ability to navigate the demands of the publishing world, which occasionally gives her an edge in the bizarre situations she encounters.
