Case Closed - Season 1 - Eps 593: The Tori's Pledge of Monkeys and Rakes (2)
It was discovered the button did not belong to any of the suspects. As Conan investigates, he is able to deduce Masuko's message when he realizes it is related to the Chinese zodiac and reveals to Kogoro that the culprit is Shinji Mizunoe. Conan explains that the ninth sign of the Chinese zodiac refers to Monkey and is written as shin (申, lit.) in Han. Nine also dictates the Sexagenary cycle where the ninth celestial stem Rén (壬) can be read in as Mizunoe in Kunyomi. As for Mizunoe's alibi, Conan explains Masuko was the original Rooster Man and Mizunoe only impersonated him in an attempt to murder him. Conan suggests to Kogoro to have the police investigate to see if the button belongs to Masuko. They discover Ran has the button and realize Mizunoe may attack her for it. Ran is tasered by Mizunoe and has her wallet taken from her. Before killing her, Mizunoe finds Ran's love fortune and reads its content which suggests Ran to be herself.
