OVA
Description
Kazuha Toyama is Heiji Hattori's childhood friend and romantic interest. Her father, Ginshiro Toyama, works as a detective at the Osaka Police station alongside Heiji's father, Heizo Hattori, forging a close connection between their families. Her mother, Sakura Toyama, appears in domestic contexts, like requesting Heiji deliver Kazuha's forgotten drink bottle.
A defining childhood incident involved Heiji locking them together with old, keyless handcuffs, forcing them to remain attached through intimate daily routines until removal. As a memento and for luck, Kazuha crafted two identical charms, each incorporating a chain link from those cuffs, which both wear constantly. She later added a picture of Heiji to her own charm pouch.
Kazuha initially mistook Heiji's frequent mentions of "Kudo" for a Tokyo girl. When Heiji invited Conan, Ran, and Kogoro to Osaka, she surveilled them, wrongly identifying Ran as her rival. She confronted Ran at an okonomiyaki restaurant, demanding she stay away from Heiji. Heiji resolved this by clarifying Ran was Shinichi Kudo's girlfriend. Kazuha's jealousy flared again over matching outfits during their next meeting, but after Ran changed, the two formed a strong friendship. Kazuha routinely stays in Ran's room during Tokyo visits.
Her personality blends a fiery temper with sharp intelligence, enabling her to solve dying messages faster than Ran or Kogoro at times. She is confrontational, expressing dislike openly, and frequently argues with Heiji. While she recognizes her romantic feelings for him and discusses them candidly with Ran, she panics and insists they are "just friends" when chances to confess arise, though determined to eventually express herself. She holds strong beliefs in spirits, good-luck charms, and superstitions, attributing unexplained events to supernatural causes. Her interests include kaiju like Gomera and Kamen Yaiba.
Physically, she has dark brown hair typically secured in a neck-length ponytail with color-coordinated ribbons, green eyes, and fair skin. She maintains an athletic build comparable to Ran's and dresses in both casual and occasionally feminine styles. Multiple characters have expressed romantic interest in her, though she often remains unaware.
Her abilities include a 2-dan rank in aikido, allowing her to subdue larger opponents, which also intimidates Heiji. She demonstrates notable deductive skills and memory retention, evidenced by her performance in karuta against skilled opponents like Momiji Ooka. She participates in cooking activities, particularly when visiting Ran, such as preparing gyoza during investigations.
Across various media appearances, she assists in cases like locating a vanished boy in Osaka by deciphering riddles to find a child's secret base, which doubled as a hideout for jewel thieves. In another case involving a stolen diamond, she accompanies Conan and Heiji investigating a ransom call and mistaken delivery. She also appears in the film "The Last Wizard of the Century" during Heiji and Conan's pursuit of Kaitou Kid.
