Description
Professor Hiroshi Agasa is a recurring supporting character in the Detective Conan franchise and appears in the 2011 special Detective Conan Magic File 2011 - Niigata - Tokyo Omiyage Capriccio. He is an inventor who lives next door to Shinichi Kudo and has been a family friend to Shinichi and Ran since their childhood. He is one of the very few people who know that Shinichi has been shrunk into the body of Conan Edogawa, and he is the first adult in whom Shinichi confides after the transformation. Agasa helps Shinichi establish his new identity, enrolls him at Teitan Elementary, and later takes in Shiho Miyano when she escapes the Black Organization, helping her become Ai Haibara. He also shares the truth about their son with Shinichi's parents. He makes his living through a number of patents and inventions, including video games, and lives in a large house with a home laboratory.
In appearance, Agasa is a heavyset man in his early fifties. He is balding on top with silver hair around the sides, has thick eyebrows, a mustache, a rounded nose, and wears round glasses. He is usually seen in casual clothing or a lab coat and owns a Volkswagen Beetle that is famously unreliable and frequently breaks down or causes trouble on trips. His appearance and manner make him look somewhat older than his actual age.
Personality-wise, Agasa is jovial, caring, outgoing, and absent-minded. He is a bachelor but acts as a paternal figure to the children around him, especially the Detective Boys. He enjoys their company, often takes them on outings and trips, and serves as an unofficial guardian and chaperone. He is proud of his work as an inventor, and while many of his creations are impractical or even cause small disasters, some are highly effective and essential to Conan's detective work. He has a particular fondness for pasta and tomato juice and is also remarkably lucky when it comes to winning prize tickets and food-related contests.
His central motivation is the safety and well-being of Conan and Haibara. He advises caution in their dealings with the Black Organization, protects their secrets, and supports their efforts from behind the scenes. He is also motivated by a genuine kindness toward the children he looks after, wanting them to have enjoyable experiences even when those outings tend to turn into criminal cases. Because he knows about the Black Organization, he is also trusted by Conan as a planning partner and a keeper of sensitive information.
In the Magic File 2011 special, which takes place after the group's return from a trip related to the film Quarter of Silence, Agasa accompanies Conan, Ai Haibara, the Detective Boys, and Sonoko Suzuki on the journey back to Tokyo. He drives the group in his vehicle, and his role during the story is largely that of driver and adult caretaker. The plot centers on souvenirs brought back for Sumiko Kobayashi and Makoto Kyogoku, which are mistakenly swapped because the two gifts look identical. When Heiji Hattori begins analyzing how the mix-up could have happened, his theories include the possibility that Agasa swapped the presents when he went back to the van during a break, as well as the idea that the gifts were exchanged when the car spun out of control or when Sonoko and Ayumi bumped into each other. Agasa is therefore part of both the comedic travel dynamic and the mystery of the swapped souvenirs, though he remains a supportive background figure rather than the central investigator.
His key relationships define much of his role in the story. With Conan Edogawa, he is a trusted confidant who treats the boy almost like a son and assists him in nearly every aspect of his double life. With Ai Haibara, he is a guardian and housemate who provides her with a safe home after her escape from the Black Organization. With the Detective Boys, he is a friendly adult who accompanies them on field trips and watches over them, and his relationship with them is characterized by mutual affection and patience. He also maintains friendly ties with Ran, Kogoro, Heiji, and the wider community, and his many connections help him explain away Conan's and Haibara's unusual circumstances by presenting them as the children of acquaintances.
In terms of development, Agasa is a largely stable presence in the franchise. The special does not show any significant personal change in him; instead it reinforces his established traits, particularly his reliability as an adult figure and the mild absent-mindedness that contributes to the group's misadventures. His most notable ability is his talent as an inventor. He has created the gadgets that allow Conan to operate as a detective while hidden in the body of a child, including power-enhancing sneakers, a voice-changing bowtie, a tranquilizer watch, a turbo-powered skateboard, and specialized glasses with tracking and communication functions. He also produces equipment for the Detective Boys, such as their badges and watches, which allow them to stay in contact and cooperate during cases. Alongside his technical skill, he shows considerable knowledge in scientific fields and occasionally contributes to solving cases through his expertise, while his poor sense of direction and unreliable car remain recurring weaknesses that define much of his comedic role during travel-based stories like this one.
