Detective Conan: One-Eyed Flashback

A violent attack on a researcher in the remote Yatsugatake Mountains draws Nagano Prefectural Police detectives Kansuke Yamato and Yui Uehara into a tense investigation. As they pursue leads, Kansuke’s long-standing eye injury suddenly flares up, suggesting a deeply unsettling connection between the current crime and his own troubled past. The stakes escalate dramatically when an ex-colleague of Kogoro Mouri is murdered shortly after probing into one of Kansuke’s previous cases. This chilling coincidence transforms a regional inquiry into a sprawling mystery with dangerous implications. Recognizing that the threads of these seemingly isolated incidents are intertwined, Conan Edogawa steps forward to untangle the web. To uncover the hidden truth, Conan joins forces with Toru Amuro and Yuya Kazami, pooling their investigative resources against a shadowy threat. Together, they must race to decipher the dark history linking the mountain assault, the old detective's fatal curiosity, and the painful secrets buried within Kansuke's past before the killer can strike again.
