Ep. 900: Locked room mystery involving Azuma Toichiro, Kogoro, Conan, and Nichiuri TV’s Tomurai-san
Aired on May 5, 2018Filler

Kogoro, Conan, and six others investigate a threat against real estate president Azuma Toichiro. After Kogoro is tranquilized, Conan solves the case, revealing the initial threat was a prank show. However, the group becomes trapped in a locked room when the dynamite fails to detach. Nichiuri TV’s Tomurai-san admits the show was a lie and seeks revenge on Kogoro for sending Utsubo to jail. She aims a gun at him, prompting Conan to defend his mentor. With his shoes under maintenance, Conan acts pitiful to stall for time. He collects water leaking from the ceiling into a bottle, using it to snatch the detonator and gun from Tomurai-san. The group pins her down, and the police arrive to arrest her.
