Kaito's childhood friend. Kaito often teases her and flips her skirt, driving her to chase him wielding her weapon of choice, a mop, even though she is secretly in love with him. She is the daughter of Inspector Nakamori, so she hates Kaitou KID. Ran Mouri from Aoyama's Detective Conan physically resembles Aoko. Like Kaito and Shinichi, the major difference in their appearances are their hairstyles.
