From Detective Conan Wiki

Canon refers to information that is considered "official" by a fictional universe's fanbase. In the Detective Conan fandom, canon refers to the official storyline and its characters, settings, and events. In many parts of the fandom and on this wiki, the word "canon" is used as a shorthand to refer to a subset of all Detective Conan works: specifically the information, storylines, settings, and characters found in the manga and information given by Aoyama Gosho in interviews. Other material is considered to be "non-canon", "extended canon", "anime/movie only", or "fanon".

Definition and background[edit]

Canon is a concept used to define what material is considered by fans to be officially part of a fictional universe's storyline. In works that have multiple contributors, such as Detective Conan which has the manga by Aoyama Gosho and many spinoffs and adaptations written by other authors, defining canon can be difficult. Sometimes the creators of the fictional-universe will outright define the scope of the canon (e.g. Star Wars), other times fans will decide based on practical considerations. Detective Conan's canon is the latter fan-defined type because it is overwhelmingly pragmatic, given the genre and story construction of Detective Conan. In addition, the various creators, including Gosho, have said relatively little about is and isn't canon.

Detective Conan canon is defined as the information, storylines, settings, and characters found in the manga and information given by Aoyama Gosho in interviews. There are two main practical reasons for this:

  1. The first is that the manga is self contained. Gosho has designed the manga story so that all mysteries in the manga can be solved using only information from the manga; knowledge of anime-only episodes, movies, etc. is not required to arrive at the correct conclusion. For instance, only characters who appear in the manga are potential suspects for the Boss of the Black Organization. It is extremely rare for useful clues for the major mysteries to show up in anime-only episodes or movies, and even when they do, those clues usually appear only after many decisive hints have already been revealed in the manga.[1]
  2. The second reason is that only the writer of the manga, Aoyama Gosho, knows the true solutions to all the mysteries. Thus, only the information and stories written by Gosho can be reliably expected not to contradict the story at a later point. For whatever reason, Gosho has only shared the solutions to the major mysteries with the editors who manage him and a few loved ones. That means other authors making adaptations are forced to make assumptions. The consequence of this incomplete information sharing is that mistakes happen in the adaptations. Alterations or omissions in the anime have introduced serious plotholes that create logical inconsistencies or remove clues so that cases are harder or impossible to solve. Even absent outright contradictions, non-canon episodes and movies can also create implications that lead to illogical conclusions.[2][3]

This relatively restrictive definition of canon excludes a considerable amount of authorized adaptation material (anime-only episodes, movies, etc) from the what is considered the "official storyline". That means sometimes character backstories or certain events that have not been re-explained in the manga are left in limbo. To reclaim this lost material, some fans classify information into canon tiers. The top tier is the strict definition of canon given above, sometimes called manga canon to distinguish it from the other tiers. All the information from the anime and movies that does not contradict the manga canon makes up the second tier: anime/movie canon or extended canon.


The following sources of information are considered to be non-canon and are not considered to be part of the official storyline by default:

  • TV original episodes (AOs)
  • Movies[4]
  • OVAs
  • Detective Conan Special
  • Video games
  • Drama specials and series
  • Novels
  • Modifications made by foreign adaptations of Detective Conan, such as name changes
  • Any change in the TV episodes that makes them different from the original manga, including additional anime-original scenes, dialogues, and information.
  • The older version any manga panels which was changed between release in Shonen Sunday and Volume release. The published Volume version is assumed to reflect Gosho's true intent because it is the corrected version.

Although the movies are confirmed to be non-canon, Gosho Aoyama has said in interviews that he's deeply involved in the creation of them and advises the writers.[5][6] There have been many times where biographical details, facts, and characters from movies are later incorporated into the manga stories.

Non-canon information that has become canon[edit]

Certain elements from non-canon sources have been upgraded into canon when they were re-introduced into the main manga by Gosho Aoyama.


Wataru Takagi[edit]

Wataru Takagi was first introduced in On Location, TV Drama Murder Case as an unnamed police detective that had accompanied Inspector Megure on the scene. For some time, this character only appeared in the TV original episodes directed by Haruo Ogawara. The character's name is first given as "Detective Takagi" in the credits for the Karaoke Box Murder Case despite his face not actually appearing on-screen. Although the Karaoke Box Murder Case was based on a manga story, Takagi does not appear in the original. Takagi receives his first manga canon appearance in the Actor's Apartment Case.

Ninzaburo Shiratori[edit]

Ninzaburo Shiratori was first introduced in The Time-Bombed Skyscraper and received his first canon manga appearance in the Treadmill Murder Case as Takagi's rival for Miwako Sato's affections.

Kazunobu Chiba[edit]

Kazunobu Chiba was first introduced in the anime version of The Final Screening Murder Case and received his first canon manga appearance in Sato's Father Case.

Azusa Enomoto[edit]

Azusa Enomoto was first introduced in The Mysterious Old Man Disappearance Case as a waitress at Café Poirot as a background character. She receives her name and first speaking appearance in The Deduction That Was Too Good. Her first canon manga appearance occurs during the Forgotten Cellphone Case.

Midori Kuriyama[edit]

Midori Kuriyama was first introduced in The Fourteenth Target as Eri Kisaki's secretary and received her first canon manga appearance in the Eri vs. Yukiko case.

Takahiro Sanada[edit]

Takahiro Sanada was first introduced in The Eleventh Striker as a new player on the Big Osaka soccer team and received his first canon manga appearance in the Kite-Flying Competition Murder Case.

Yuya Kazami[edit]

Yuya Kazami was first introduced as Amuro's PSB subordinate in Movie 20: The Darkest Nightmare and received his first canon manga appearance in File 998: Haibara's Lost Phone Strap Case.

Special Circumstances[edit]

Momiji Ooka and Muga Iori[edit]

Originally Momiji Ooka was a character created for Movie 21 for the purpose of being a love rival in the Heiji/Kazuha relationship. On the Movie 20 celebration on 04/15/2016, Aoyama decided to let Momiji briefly show up in the manga series so that her later appearance in M21 wouldn't seem too abrupt. Muga Iori was originally designed by Aoyama himself, however his original design was to be an old man, then later changed to a young man.[7]

  1. ^ Note: More recent movies since Movie 18 have connected with ongoing storylines. In Movie 18, Okiya was shown speaking in Akai's voice for a single line. While decisive, this clue was very late relative the the number of major hints given in the manga and anime-adaptations.
  2. ^ *For instance, in Movie 13, the Black Organization attacked the Tokyo Tower with a military helicopter. This leads to strange questions about how they obtained such powerful military equipment at a moment's notice, and how they could fly it into the heart of Tokyo without attracting the attention of Japan's self-defense airforce or the US military stationed in Japan. In addition it creates a contradiction since the Organization is supposed to value secrecy, yet such a brazen and stunning attack would surely attract the entire world's attention and extremely potent law enforcement attention from many countries.
    The problem only becomes worse in Movie 20 where the Black Organization manages to scramble a Bell Boeing V-22 Osprey. At the time of the movie's release, only the US military operated such craft. The closest base to Tokyo where they would be housed is about 400 miles away in Iwakuni in Yamaguchi Prefecture. For the Black Organization to gain control of a V-22 (there are less than 300 in existence), they would need intelligence and operations skills and resources that surpass those of world powers like China or Russia.
  3. ^ Initially, the first four movies and manga disagreed about Kogoro's skill as a police officer and detective. The movies implied that Kogoro was lazy and foolish, but he had occasional flashes of brilliance and useful skills as an officer, like masterful marksmanship. In contrast, the manga implied he was thoroughly terrible as an officer. Eventually, Gosho adopted the idea that Kogoro could muster up some ability in particular situations.

    Q: During one of the movies Sonoko got a different hairstyle (see movie 5). Is she also going to get this hairstyle in the manga version?
    A: Die Filme und die Manga sind völlig getrennt. Im Manga wird Sonoko also ihre alte Frisur behalten.
    A: The movies and the manga version are completely separated from each other. So Sonoko will keep her old hairstyle in the manga version.
