Overview: Conan, Kogoro, Ran, and Sonoko are at a tea house when a woman wearing gothic lolita fashion clothing enters the tea house, orders a glass of water, and leaves. Ten minutes later, a woman named Yuika Shoudou, arrives to the tea house where they learn that she was supposed to meet with the gothic girl from before. The four then leave to go shopping. On the way, a pair of thieves tries to steal their shopping bags by spilling ice cream on Ran and Sonoko but are foiled by Conan. The girls are forced to change in a public restroom where they find the gothic girl from before dead. The cell phone of the deceased, Mihiro Kuze, reveals she had been receiving phone calls from Shoudou. The police confirm with the waitress at the tea house that Kuze and Shoudou arrived ten minutes apart and with the public restroom thirty minutes away, removes Shoudou as a suspect.
