Reiko Catherine Akimoto, also known as Reiko Katherine Akimoto, serves as a patrol officer at the police box in front of Kameari Park. She possesses mixed Japanese and French heritage, with her Japanese father leading the Kobe-based Akimoto Trading Zaibatsu and her French mother. Raised initially in France before relocating to Japan, her high-class education cultivated expertise in cooking, ballet, music—specializing in violin and piano—and sports. This background also fostered multilingual abilities, including claims of speaking up to thirty languages. Physically distinctive, she has waist-length blonde hair often styled in pigtails or bobs off-duty, while her eyes alternate between blue in manga and amber in anime. Her tall frame measures 95-59-90 centimeters. On duty, she wears a signature pink uniform featuring a short skirt and coat, with summer variants having shorter sleeves. The manga accentuates her cleavage more prominently than the anime’s restrained depiction. Outside work, she adorns expensive, fashionable attire. Her personality blends approachability, empathy, and helpfulness—she routinely offers colleagues advice or tea during downtime. Combining beauty and intellect, she provides global perspectives contrasting with peers like Ryotsu’s localized outlook. Alongside Nakagawa, she frequently opposes Ryotsu’s hazardous schemes out of concern, though rarely thwarting them. Despite frequent romantic advances sparked by her appearance, she displays minimal interest. Her birthday coincides with Japan’s Tanabata festival on July 7. Family includes her younger sister Yu Akimoto and mother Francoise Akimoto. Her father, Pyunpyunmaru Akimoto, embarrasses her with persistent marriage inquiries, provoking irritation. Professionally, she shares a casual, affectionate dynamic with Ryotsu, addressing him as "Ryo-chan," and acts as Nakagawa’s female counterpart due to their shared wealthy, mixed-heritage backgrounds and refined upbringings—calling him "Kei-chan." Their interactions explore diverse topics inaccessible to other colleagues. She maintains a positive rapport with superior Daijiro Ohara (Bucho), who trusts her diligence. As one of the series' three central characters alongside Ryotsu and Nakagawa, she remains a consistent presence despite being introduced last. Her core traits and relationships show minimal evolution across media, including films. In the 1999 movie, she fulfills her standard professional duties.
