**Sonoko Suzuki** is the second daughter of Shiro and Tomoko Suzuki, heirs to a vast corporate fortune ranking among Japan's largest. Her family includes older sister Ayako and eccentric cousin-uncle Jirokichi Suzuki, famed for his clashes with the phantom thief Kaitou Kid. While her family's immense wealth grants access to exclusive vacations, designer fashion, and high-society events, Sonoko displays unexpected humility regarding her privilege, never exploiting her status for social gain or compromising authentic connections. Her deepest bond is with childhood friend Ran Mouri, a relationship enduring since kindergarten despite their differing backgrounds. Ran's consistent refusal of financial assistance, like declining funded ski trips, fosters mutual respect over material concerns. Sonoko provides steadfast emotional support, defending Ran against childhood bullies and playfully teasing her about Shinichi Kudo. Initially defined by boy-crazy impulsiveness, Sonoko actively pursued romance through tactics like crafting chocolates, wearing revealing outfits, and attending male-centric gatherings. This sometimes sparked jealousy when Ran unintentionally attracted her crushes, though their friendship remained unshaken. Her romantic focus solidified after meeting Makoto Kyogoku, "The Prince of Kicks," an international karate champion who rescued her from a serial killer during an Izu vacation, igniting mutual affection. Despite the challenges of Makoto's competition schedule and overseas studies creating a long-distance relationship, Sonoko demonstrates fierce loyalty. She crafts handmade gifts like sweaters and photo-adorned letters, and famously molded a clay cup mistaken by Makoto for a vase. She formally introduced him to her approving parents. Though she retains a tendency to flirt, especially with Kaitou Kid, her commitment to Makoto is central, highlighted when he braved a snowstorm after misinterpreting her Valentine's chocolate plans. Conan Edogawa periodically uses Sonoko as a deduction mouthpiece, employing his stun-gun watch to render her unconscious before mimicking her voice and mannerisms—a skill he initially found difficult but mastered. Sonoko, unaware, embraced the self-styled title "Deduction Queen," believing herself a skilled detective during these trances. While Conan occasionally regrets fostering this misconception, he recognizes her genuine courage in dangerous situations. Sonoko has also independently contributed to cases, interpreting Conan's charades while he was ill or solving minor puzzles herself. Her personality blends spontaneity, dramatic flair, and occasional insensitivity, particularly when mocking Ran's romantic worries. She indulges in extravagant shopping, enjoys pop music like the band LEX, and relishes sugary festival treats, once even using Conan to get child-discounted food. Sonoko exhibits formality in speech, using honorifics like "Oji-sama" for her uncle, yet casual terms like "Papa" for her father. Despite her boldness, encountering corpses typically provokes screams. Key appearances include confronting a bandaged assailant at a mountain villa, meeting Makoto during the Izu trip, and the "Bloody Valentine" case where Makoto misunderstood her chocolate preparations. In non-canon stories, she directed a charity play in OVA 8, though illness forced Ran to replace her during the performance. Film appearances feature altered hairstyles, such as a perm in *Countdown to Heaven*. Physically, Sonoko stands 165 cm tall with short light-brown hair, often secured by an orange bandana. Her typical casual attire of skirts and blouses tends towards greater skin exposure than Ran's, initially chosen to attract male attention.
