Meitantei Conan

Synopsis

Ayumi is going to Sawaki Yoko’s dentistry office to get rid of a baby tooth and she decides to keep a Masked Yaiba card with her for good luck. Meanwhile, Nakamoto Katsuhiko, a real estate manager and Yoko’s neighbor, is viciously murdered when he is stabbed in the heart with a syringe by someone knocking at his door. Yoko discovers Katsuhiko’s corpse near her apartment in his condominium and his time of death is exactly 7:30PM. The police suspect Yoko because she has a motive, but she also had an alibi. She was with Ayumi at her office watching the TV show Masked Yaiba at that time. While visiting her apartment, Conan realizes the illusion used and accuses Yoko as the murderer. She decorated her apartment to look exactly like the waiting room at her dentist office and, using two sedatives and her car, convinced Ayumi she was at the office the entire time when at one point they were in her condo, at exactly 7:30PM when the crime took place. To incriminate Yoko, Ayumi placed the Masked Yaiba card from the office trading card deck into the condo trading card deck. Yoko confesses and states revenge as her motive, Katsuhiko kidnapped then murdered her brother with her as a witness but due to her being young, the case was dropped. Yoko turns herself in without resistance.
