Yamato, Kansuke

大和敢助

Yamato Kansuke serves as a police inspector in Nagano Prefecture. Detective Uehara Yui works directly under him. Yamato lost his left eye to a snow avalanche, leaving an X-shaped scar in its place. That same avalanche inflicted severe, permanent damage on his left leg, compelling him to rely on a forearm crutch for mobility.
Yamato spent his childhood in a small Nagano village alongside Uehara. Like many villagers, he deeply admired Kai Kuroto, a police officer and local hero who inspired both Yamato and Uehara to pursue careers in law enforcement. One year prior to the Fuurinkazan Case, Yamato pursued a parole violator he suspected of involvement in Kai’s mysterious death into the mountains, where he became trapped in the avalanche that cost him his eye and leg. He was missing and presumed dead for several days until Morofushi "Koumei" Taka'aki, a school friend and fellow police inspector, defied orders to track the criminal and locate Yamato. Upon recovering, Yamato returned to duty and continued his investigation into Kai’s death.
Unlike other inspectors such as Megure, Yokomizo, and Yamamura, Yamato is portrayed as intensely serious and hard-boiled. He is frequently short-tempered and has a reputation for yelling at and intimidating suspects. This facet of his personality makes him visibly irritated by Kogorou’s ignorance and Yamamura’s goofiness. Nevertheless, he possesses softer sides, though he rarely displays them, and there are indications that he is both aware of and accepting of Uehara’s affection for him. With assistance from Conan and Heiji, the case was eventually resolved, and Uehara soon rejoined the police force as his partner.
Yamato maintains a petty rivalry with fellow detective Koumei, often competing to see who can solve a case first. Despite this competition, they remain close friends, and Yamato was once willing to enter a burning mansion to save him. Yamato also recognizes Conan’s intelligence and is among the few characters who treats him as an adult and an equal.
