Konatsu Shinjō is an idol dietwoman from Aichi Prefecture and a member of the Sunlight Party, belonging to the idol unit A.I.S. She has black hair that reaches her shoulders and gold eyes. Her most prominent trait is an intense passion for detective work; she styles herself as a Japanese‑style Holmes and displays extraordinary curiosity and initiative, immediately diving into any case or mystery she encounters. When she presents her deductions she gives an impression of intelligence, but her reasoning is often flawed and tends to go far off track. Despite these frequent missteps, she never loses motivation and cherishes the dream of becoming a detective idol who works on an international stage. Her personality is a blend of outward calm and coolness with an easily excitable, upbeat nature that often lifts the spirits of those around her. Within the story she serves a supporting role, taking part in political activities and idol performances alongside her unit. She forms close, cooperative bonds with the other A.I.S. members, and throughout the series she persists in pursuing her investigative ambitions with unwavering optimism. Her notable strengths lie in her relentless curiosity and her ability to energize a group, even when her attempts at solving mysteries prove misguided.
