Okino, Youko

沖野ヨーコ

Okino Youko is a young pop idol who is regularly worshipped by Mouri Kogorou. She makes numerous cameos throughout the series, primarily appearing as a prominent guest at social gatherings that evolve into criminal cases.
Youko began her idol career as a member of the quartet "Earth Ladies," alongside Kusano Kaoru, Takeno Yuki, and Hoshino Terumi. The group achieved considerable success, but they eventually disbanded to pursue individual careers. Youko has continued to be successful and quite popular in the pop idol and acting industries.
Youko first met Conan, Mouri, and Ran when she requested Mouri's assistance in catching a stalker who had even breached her apartment (and naturally, Mouri did not hesitate to accept the case). However, inside the apartment, they discovered an unknown man impaled on a knife, transforming the situation into a murder investigation. Soon after, Conan deduced that the 'victim' had actually committed suicide: the man was Fujie Akiyoshi, Youko's former boyfriend who still loved her. Due to a fatal misunderstanding, Fujie fell into despair and threw himself onto the knife, staging it to look like a murder in order to take revenge on Youko. Fortunately, Conan uncovered the truth before any damage could be done to Youko's career.
Having overcome her grief, Youko has continued her career and has remained a friend and valuable contact for Conan and Mouri within the TV and idol industries ever since.
