Yoko is a modest and friendly person whose fame hasn't got into her head and is devoted to her friends and fans; perhaps one of the reasons she has remained popular to this day. Yoko first met Conan, Kogoro and his daughter Ran when she asked for Kogoro's help in apprehending a stalker who had even penetrated her apartment _(and of course, Kogoro would not hesitate to take the case)._ But in the apartment they found an unknown man impaled upon a knife, turning this case into a murder investigation. Soon, however, Conan figured out that the 'victim' had actually committed suicide: The man was Akiyoshi Fujie, Yoko's old boyfriend who still loved her. Due to a fatal misunderstanding, involving Fujie mistaking Yuko for Yoko, Akiyoshi fell into despair and plunged himself onto a knife, making it appear as if he had been murdered by Yoko in order to take revenge on her. Luckily, Conan found out the truth before damage could be inflicted on Yoko's career. Overcoming her grief, Yoko has carried on her career and has remained a friend and valuable contact to Kogoro and Conan in the TV and idol industry ever since. She has also gone on to appear in several movies, such as "Kiss Note" and "Zombie Blade". Kogoro Mouri is completely infatuated with the young popstar and has all of her appearances in movies and music on tape and DVD, and has even once appeared on her cooking show. Yoko in turn considers Mouri, Ran, and Conan to be good friends. She often suggests Kogoro for participation in her TV shows and commercials, and often invites him, Ran and Conan to parties and dinners. However, the latter often tend to evolve into murder cases.
