Kaito Kuroba has also made significant appearances in Aoyama's "Case Closed" series. His strong resemblance to the protagonist of this series, Shinichi Kudo, allows Kaito to impersonate him without a mask. He is also voiced by the same voice actors as Shinichi. When "Case Closed" was localized into English, Viz Media chose the rōmaji Kaito Kid for the manga, while Funimation Entertainment and Discotek Media refer to him as Phantom Thief Kid/Kid the Phantom Thief, respectively, in the anime. Shogakukan Asia also chose to use Kaito Kid.
