Detective Conan: First Arc

The long running series Detective Conan (Case Closed in the west) first began serialization in 1994, while the anime first aired in 1996. Unlike other Shonen Series such as One Piece or Fairy Tail, it is much more difficult to pin down seasons as the series is pretty episodic with an overarching plot that has yet to be resolved. For the purposes of this post, I will cover episodes 1 to 128, as this makes up the first chunk of the series and takes place before one of the most important plot points in the series. The series itself is still going at 812 episodes and counting.

The first 128 episodes of Detective Conan establishes the overarching plot of the series as well as the main characters in the series and some very important side characters. The series centres around high school detective Shinichi Kudo, who assists the police in solving a variety of cases. During one such case, Kudo was attacked by members of a crime syndicate known as the Black Organization and forced to take an experimental drug which instead of killing him, reverts him to an elementary student. Through the help of his friend Dr. Hiroshi Agasa, Kudo went and lived with his childhood friend Ran Mouri and her detective father Kogoro Mouri, in the hopes of finding more information about the Organization under the alias Conan Edogawa.


  • Interesting cases and scenarios
  • Can jump in and out of the series
  • The solution to the cases are always logical and thoroughly explained
  • Introduces many interesting characters such as Hattori Heiji and Kaitou Kid
  • The character growth of Conan Edogawa is evident as the series progressed


  • Very episodic and most episodes have no direct connection to the Black Organization, so can be seen as filler
  • The cases always follow a specific format, and after a while it can get repetitive
  • Plot developments tend to be forgotten after a few episodes

Characters   -   7 / 10

Detective_Conan_PosterThe first arc introduces a lot of the characters that will gone on to play  major roles in the series, however, only Conan and few other characters get any serious character development or exposition. For example, Kudo changed his philosophy when it comes to dealing with criminals after seeing what happens when he drives a criminal over the edge. As Conan, he becomes more sociable as the series goes own and assists in solving cases that involve his elementary school friends. Many of the other characters, such as Kaitou Kid and police officers that cooperate with Kogoro and Conan, are merely introduced, but their personalities and backgrounds were not touched upon until later in the series.

Music   -   10 / 10

The music used in Detective Conan is excellent. All of the scene setting music is still being used today. After watching a few episodes, you can get a sense of what the scene is going to be like based on just the background music. In addition, the first arc also uses some amazing opening and ending themes, and one of my favourites is in the video below.

Plot   -   8 / 10

Detective ConanWhile episodic, a lot of the cases are very enjoyable and also challenges you to try to figure out the identity of the culprit along with the main cast, as most if not all the cases, facts are shown to the audience as Conan finds them. It is also very easy to see which episodes will be relevant to the main plot or significant for character development, because they tend to be  hour long to 2 hour specials. These include the One Billion Yen Heist, which ends the first portion of Detective Conan and sets up the second portion, as well as The Naniwa Serial Murder Case, which introduces very important characters and character dynamics that is still being used to the current arc of the series.


Very engaging cases and likeable characters help introduce us to one of the longest running anime series of all time.
  • Character Development of Kudo as Conan
  • Music
  • Well-reasoned Solutions
  • Slow progression
  • Filler
  • Need to be familiar with Japanese culture to understand some of the solutions
