The Promise with the J-League

Ran is almost attacked by "The Hooded Man" after staying late at school for her extracurricular activities but defends herself. A scream is heard and Conan correctly deduces the man to be the aforementioned criminal who is arrested. They manage to save his latest victim, Mizuki Tachibana, but her friend, Yoko Katsuragi, is found bludgeoned to death, allegedly by the same man. He denies involvement but the similarities in the previous cases are too great to ignore. After finding unusual clues, Conan puts Kogoro to sleep to reveal that Mizuki killed Yoko. Mizuki was attacked by the Hooded Man but saw it as an opportunity to frame him for Yoko’s murder. As evidence, Mizuki has been followed by Ran for the majority of the time; she didn‘t have time to dispose of the clothes and weapon used in the crime, meaning she is still in possession of them. Mizuki confesses that Yoko took everything, including her boyfriend, from her.
