At the theaters, the Detective Boys run into Shiratori who is depressed since Sato's affection is being directed towards Takagi. Shiratori reveals that he is bind to Sato because of an encounter he had with her in the past. Shiratori explains Sato as a young girl stood up to two thieves by herself.

During the movie, Shiratori runs into a woman named Nami Kasakura who offers him a drink with paper folded sakuras causing Shiratori to consider the possibility she was the girl in the past. After the movie, Kasakura tells Shiratori she is being stalked and asks him to investigate. At her apartment, Kasakura's boyfriend is found dead. Conan suspects Kasakura but her alibi supposedly states she was at the theater the whole time.
