Initially, series creator Gosho Aoyama planned for Yui to be the culprit in the Furinkazan case. He later changed his mind, spending two hours revising the script to make her a heroine instead. Key Traits and Roles
Yui is a core member of the talented Nagano Prefectural Police trio, alongside the hot-headed Kansuke Yamato and the stoic, tactical Taka'aki "Koumei" Morofushi.
While typically friendly and considerate, she has shown moments of being "not so above it all," such as screaming like a schoolgirl during the "Red Woman" case when jokingly told about a ghost.
