Nana emerges as a minor antagonist in the TV special, collaborating with legendary hitman Junitsu Kondo and accomplices to execute a plot involving explosives concealed within tin cans stored in a bathhouse locker. After fatally shooting two men during the operation, she identifies Kondo as her sole remaining partner. She orchestrates a scheme to remotely detonate hidden explosives via a backpack worn by Conan Edogawa during a festival, exploiting a staged accident to manipulate his perceived amnesia. Unbeknownst to her, Conan feigns memory loss to infiltrate the conspiracy and expose its architect. Nana’s downfall arrives when Kondo uncovers her duplicity, administering a sleeping pill originally meant for Conan to subdue her. Though central to advancing the explosives plan, she remains oblivious to Conan’s ruse, her role strictly confined to the operation’s mechanics. The narrative focuses solely on her criminal actions, omitting personal history or motivations beyond her tactical involvement.
