After returning to Detective Mouri's agency, Heiji asks them to help find Teruaki Kunisue, a sophmore at Teitan University who Heiji accidentally gave Kazuha's lucky charm. They all head to Teitan University the next day only to find out that he has not been attending classes due to a broken wrist. Ran learns from Kazuha that she left a photo of Heiji in it and does not want Heiji to find out about the charm's contents. Later, Ran, Conan, Heiji, and Kazuha, go to a sports parlor where Teruaki is suppose to be only to discover from the police that Teruaki has been assaulted by an unknown assailant. They are able to narrow down the suspects to three people since they were not in the bar during the time of the attack.

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 Shodo, arrives to the tea house where they learn that she was suppose to meet with the woman 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.
