Eisuke is Ran's new classmate. The two met shortly following the Black Impact incident in which the FBI apprehended a member of the Black Organization via a fluke accident in which Eisuke appears very curious about.
His deductive skills are not very impressive, though Detective Moore has offered Eisuke the opportunity to visit his agency at any time. Eisuke seems to have impecable timing throughout his short time in the series as he is accident prone.
Eisuke is suspected of assisting the Black Organization; however, it is unclear as to who he works for or if he is actually a member of the Black Organization. For instance, in one case, Eisuke broke down in tears because he was "unable to solve the mystery." Though suspicions regarding Eisuke's true identity for Case Closed enthusiasts increases as Vodka says to himself "Hondou... Hondou... Hondou..." This incident combined with Eisuke's similarities to Rena Mizunashi has led Conan to believe that the two are related; however, viewers may infer that the Black Organization's relation with Eisuke goes deeper. In File 604, It is revealed that Rena actually is Eisuke's sister Hidemi, who is a CIA agent like their father Ethan. After Mizunashi returns to the Black Organization, the FBI tries to get Eisuke to enter the witness protection program. However, Eisuke returns in File 619, and has refused to be protected by the FBI. Surprisingly in File 621, Eisuke reveals to Conan that he is in love with Ran, and that he wants to travel to America to become a CIA agent and take her with him. Conan refuses and tells Eisuke his true identity as Kudo Shinichi. Eisuke only laughs and tells Conan he had suspected it all along. Before leaving, Eisuke asks Conan to make Ran happy.
