Kenji Hagiwara (萩原 健二,Hagiwara Kenji?) is a character in the manga and anime franchise Detective Conan.
Background
Kenji Hagiwara was a member of the Tokyo Metropolitan Police Department bomb squadron and Jinpei Matsuda's explosive disposal partner. He died in the first of a series of bombings seven years prior to the current timeline.
In the case, there is a flashback of seven years ago in a residential building where two bombs were planted by two serial bombers who had just started his bombing spree. Jinpei Matsuda defused the first with ease and the city paid the ransom for the 2nd bomb so the bombers stopped the bomb. The 2nd bomber died as he panicked when he ran and to avenge himself, the other bomber restarted the second bomb. Kenji Hagiwara and a few other squad members where called to room twenty on the floor before the last to defuse the bomb. At first, the squad members took a pause to wait until everybody had been evacuated and Kenji lit his cigarette to chill. Everybody waited patiently until they received a call from the operators telling them they could start. Then, as they got started, Hagiwara's friend Jinpei Matsuda called him to tell him to quit playing and to defuse it already but Hagiwara told him the bomb's timer stopped. Upon analyzing the bomb, he deduced the bomb would take a bit more than 3 minutes to defuse but he quickly realized that there were only 6 seconds left and unfortunately, part of the squad members died along with Hagiwara. 6 years later, it was Matsuda's turn to die and that year, the bomber multiplied his attacks.
