## History[[edit](/wiki/index.php?title=Detective_Boys&action=edit&section=1 "Edit section: History")]
The Detective Boys were informally founded when [Ayumi Yoshida](/wiki/Ayumi_Yoshida "Ayumi Yoshida") and [Genta Kojima](/wiki/Genta_Kojima "Genta Kojima") decided to [investigate a mansion](/wiki/A_Haunted_Mansion_Murder_Case "A Haunted Mansion Murder Case") which was once a murder site and had been abandoned. Conan and his classmate [Mitsuhiko Tsuburaya](/wiki/Mitsuhiko_Tsuburaya "Mitsuhiko Tsuburaya") were drafted into accompanying the two, and the foursome entered the house. In the course of this adventure, Conan found out that the house was still inhabited by the mother and son of the murder victim; the son had killed his father in a fit of rage over his abusive behavior, and his mother had subsequently locked her own son in a dungeon beneath the house to wait until the deed's time-bar had passed. After Conan succeeded in exposing the two, they were arrested and the case was resolved.[](#cite_note-1)
In time, the four kept stumbling into more and more criminal cases, which were resolved thanks to Conan's deductive skills and initiative. Particularly after the case involving a sizable cache of stolen Italian gold coins[](#cite_note-2), Ayumi, Genta and Mitsuhiko developed a taste for detective work and impulsively decided to become investigators themselves, mostly for fame and glory. After advertising their services in school[](#cite_note-3), they have become actively involved in many criminal cases provided by their schoolmates, though more often than not they keep accidentally coming upon such during their free-time activities. Some time later, their new classmate (and former [Black Organization](/wiki/Black_Organization "Black Organization") member) [Ai Haibara](/wiki/Ai_Haibara "Ai Haibara") was drafted into the group and replaced Mitsuhiko as the second-in-command. Two adults also joined this group informally, namely Professor [Hiroshi Agasa](/wiki/Hiroshi_Agasa "Hiroshi Agasa"), who provides the group with special gadgets to aid them in their adventures, and their class teacher [Sumiko Kobayashi](/wiki/Sumiko_Kobayashi "Sumiko Kobayashi"), a mystery novel enthusiast who proclaimed herself their manager.
In most cases, the Detective Boys act more like aides to Conan, who is the group's (mostly undisputed) leader due to his intelligence, extensive criminal knowledge and experience. In this role they function mostly as additional pairs of eyes who provide Conan with trivial-seeming but important clues, and display little investigative brilliance or determination of their own. As the series progresses, however, the other members, particularly Ai and Mitsuhiko, have demonstrated in some cases, especially where Conan is not present or out of commission, that the Detective Boys have the potential of becoming skilled investigators in their own right. Famous cases of such include:
**Manga**:
* Chapter 251-253: [Dangerous Cave Case](/wiki/Volume_25#Dangerous_Cave_Case "Volume 25")
* Chapter 548-549: [Kobayashi-sensei's Mystery](/wiki/Volume_53#Kobayashi-sensei.27s_Mystery "Volume 53")
* Chapter 712-715: [Kaitou Kid and the Kirin's Horn](/wiki/Volume_68#Kirin.27s_Horn_Case "Volume 68")
* Chapter 753-755: [Two-Five-Two](/wiki/Volume_72#Two-Five-Two "Volume 72")
* Chapter 759-761: [Wolf-Crier](/wiki/Volume_72#Wolf-Crier "Volume 72")
**Anime**:
* Episode 182: [The Big Investigation of the Nine Doors](/wiki/The_Big_Investigation_of_the_Nine_Doors "The Big Investigation of the Nine Doors") (TV original)
* Episode 225: [The Secret of the High Sales](/wiki/The_Secret_of_the_High_Sales "The Secret of the High Sales") (TV original)
* Episode 303: [The Victim Who Came Back](/wiki/The_Victim_Who_Came_Back "The Victim Who Came Back") (TV original)
* Episode 936: [Intrigue at the Food Court](/wiki/Intrigue_at_the_Food_Court "Intrigue at the Food Court") (TV original)
**Movie**:
* Movie 13: [The Raven Chaser](/wiki/The_Raven_Chaser "The Raven Chaser")
* [Lupin III vs. Detective Conan: The Movie](/wiki/Lupin_III_vs._Detective_Conan:_The_Movie "Lupin III vs. Detective Conan: The Movie")
**OVA**:
* OVA 07: [A Challenge from Agasa! Agasa vs. Conan and the Detective Boys](/wiki/A_Challenge_from_Agasa!_Agasa_vs._Conan_and_the_Detective_Boys "A Challenge from Agasa! Agasa vs. Conan and the Detective Boys")
* OVA 11: [A Secret Order From London](/wiki/A_Secret_Order_From_London "A Secret Order From London")
**Note:** Caution must be advised for OVAs, movies and TV originals, as these are essentially non-canonical with the manga series and therefore not 100% diagnostically conclusive.

## Relationship analysis[[edit](/wiki/index.php?title=Detective_Boys&action=edit&section=4 "Edit section: Relationship analysis")]
### Family and friends[[edit](/wiki/index.php?title=Detective_Boys&action=edit&section=5 "Edit section: Family and friends")]
#### Hiroshi Agasa[[edit](/wiki/index.php?title=Detective_Boys&action=edit&section=6 "Edit section: Hiroshi Agasa")]
The Detective Boys love Professor [Hiroshi Agasa](/wiki/Hiroshi_Agasa "Hiroshi Agasa") very much and they have a good familial relationship with each other. Professor Agasa has invented the 'Wristwatch Flashlight' and the 'Detective Boys Badge' to help them in their deductions and to contact each other in any situation that might come up.
Agasa, in turn, seems to consider the actual children of the group as surrogate grandchildren, and is willing to help them with various cases.
#### Sumiko Kobayashi[[edit](/wiki/index.php?title=Detective_Boys&action=edit&section=7 "Edit section: Sumiko Kobayashi")]
Sumiko Kobayashi is the current teacher of the class that the Detective Boys are in. She also proclaims herself to be their manager, much to the children's chagrin.
#### Rumi Wakasa[[edit](/wiki/index.php?title=Detective_Boys&action=edit&section=8 "Edit section: Rumi Wakasa")]
Since becoming assistant teacher in the Detective Boys' class, she has gone on a number of outings with them. She is secretly highly skilled at fighting and has protected the Detective Boys on a number of occasions. She also has very sharp deduction skills and has had to drop hints for Conan on the cases they've had together. However, there are indications that she is using the Detective Boys to her own ends.
