S01E579 — The Thirteen Black Suggestions

The man explains he was knocked unconscious in the bathroom and found himself like that and that the bomber threatened that if anyone leaves the floor or calls the police, the bomber will detonate the bombs on that floor. He discloses the bomber's demands, to find the sender of thirteen red shirts. Meanwhile, Jodie has been searching for evidence of Akai in the department store. While Conan and Kogoro investigate, Conan discovers from the receipt that the shirts were bought on different days but always at 12:28 and that there are creases on the thirteen red shirts. At the same time, the Black Organization waits outside the department store with snipers waiting for Akai. Gin holds a gun to Kir's head explaining that if Akai is alive, he will kill her.
