Heiji Hattori and Kazuha Toyama

Heiji and Kazuha

Heiji Hattori and Kazuha Toyama serve as the beta couple for Detective Conan and a foil for Shinichi Kudo and Ran Mouri's relationship.

Relationship analysis

Heiji and Kazuha grew up together and are easily each other's best friend. Neither of them have been shown to have other close friendships, though Heiji does have a rivalry with fellow kendo practitioner Okita. They often spend time together, and Kazuha typically comes along when Heiji visits the Mouri's or vice versa, getting caught up with Heiji in the criminal investigation. Kazuha and Heiji both wear good-luck charms that Kazuha made with pieces of the handcuff chain that stuck them together temporarily as children. Kazuha and Heiji have both shown jealousy when the other appears interested in someone else, but they are not officially in a romantic relationship. Kazuha has demonstrated awareness of her affection for Heiji, but has been either too shy or otherwise interrupted any time she tries to tell him. Heiji, in contrast, is either emotionally oblivious or purposefully ignoring his feelings for Kazuha for most of the series. Heiji has yet to attempt any sort of confession to Kazuha, but he is very protective of her. In one of the most recent cases, Heiji thought that Kazuha was being taken away by a couple of strange men. Furious, Heiji pins the guy holding Kazuha and yells at him saying "Whatcha doin' to my Kazuha?!". Seemingly confessing that she's his girlfriend out loud. But because he's too embarrassed to admit his own confession, he says that she has no proof to say that he actually confessed to her.
