Heiji is a high school detective, and the son of [Heizo Hattori,](https://anilist.co/character/30367/Heizo-Hattori) chief of the Osaka Police Department, and his wife [Shizuka Hattori.](https://anilist.co/character/41038/Shizuka-Hattori) Heiji wants to be a detective like his father since spending his childhood looking for lost cats in his neighborhood, and he is also very skilled in kendo and has become a favored tournament contender for his school. 

At one time during their childhood, Heiji had had the unfortunate idea of locking himself and his friend [Kazuha](https://anilist.co/character/3198/Kazuha-Toyama) together with a set of old handcuffs which had no key to unlock it; as a result they involuntarily had to spend time together even on some rather intimate occasions _(i.e., bathroom visits)_ before the cuffs could be removed. As a reminder of this 'closeness' and for good luck, Kazuha fashioned two identical lucky charms, each incorporating a chain link from the cuffs, which she and Heiji have been wearing ever since.

In the news, Heiji has been publicly declared the "Great Detective of the West", while [Shinichi Kudo](https://anilist.co/character/1742/Conan-Edogawa) is the "Great Detective of the East". As a result, Heiji showed up unannounced at the Mouri Detective Agency looking for Kudo, seeking to challenge his rival to a showdown of wits. _(In fact, they had such a contest before, three years previously, during a skiing trip in the Yamagata prefecture, although they never learned about each other's identities at that time.)_ Heiji was soundly defeated in the following case after Conan Edogawa temporarily turned back into Shinichi, but he gained a lot of respect for Shinichi in the process.

During their second encounter, Conan knocked Heiji out to use him as the mouthpiece for the voice-changing bow-tie. But during his final presentation of the facts, Heiji awoke prematurely and discovered Conan's secret, and in the end managed to blackmail Conan into revealing all. Ever since that revelation, Heiji has been helping Conan in hiding his secret identity, though he constantly slips up by calling him "Kudo" in front of [Ran](https://anilist.co/character/1748/Ran-Mouri) and Kazuha. 

Heiji and Conan most often congenially team up to solve assorted cases. Heiji has also helped Conan investigate the Black Organization on several occasions, such as when the two investigated [Jodie Starling,](https://anilist.co/character/26754/Jodie-Starling) or when Heiji investigated [Eisuke Hondou](https://anilist.co/character/5351/Eisuke-Hondou) on his own and then told Conan his findings, but he never had a real direct confrontation with the primary antagonist. He has also helped cover for Conan during several of the brief instances where Conan regained his true adolescent age, and has even disguised himself as Shinichi on several occasions in order to protect his identity, even though he is not very good at it _(mostly owing to his distinctive Kansai dialect)._ When not working on a case, he regularly attempts to invite Conan to take in the sights and culinary delights of Osaka, which he considers more wholesome than Tokyo's.

A short, hairless (for most of the series) warrior monk, loyal Kuririn provides comic relief during tense moments. Like Chiaotzu, Kuririn doesn't have a nose. He is a good-natured, outgoing and competitive martial artist.  Once a fierce rival of Son Goku, he quickly became his best friend while training under Muten Roshi. He also is close to Goku's son, Gohan. <div rel="spoiler">He eventually marries Android 18 and settles down, having a daughter named Marron.</div>

He is the President of the Computer Research Society Club, which shares a room adjacent to the SOS Brigade. The President is never given a name other than "Computer Society President" or variations upon that term.

He and his club had the misfortune of being targeted by [Haruhi Suzumiya's](https://anilist.co/character/251/Haruhi-Suzumiya) blackmail, being forced to give away their best computer and wire the Brigade's clubroom for an internet connection. He hasn't yet forgiven this, and frequently checks the SOS Brigade website to see if they are putting the computer to use (which they haven't), making him the primary cause of their hit counter's steady rise. He has a passion for computers (duh) and along with the other four members of the Computer Society, helped developed their own basic science-fiction strategy game titled The Day of Sagittarius III (there is no Day of Sagittarius I or II, they just thought the III would sound cool). It is hinted he is one of [Yuki Nagato's](https://anilist.co/character/249/Yuki-Nagato) secret admirers.
