## Background[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=1 "Edit section: Background")]
Tsukumo is a police detective working for Shizuoka Prefectural Police's headquarters and has been recently affected to the position or paired with [Yokomizo](/wiki/Sango_Yokomizo "Sango Yokomizo"), since he doesn't know about [Kogoro](/wiki/Kogoro_Mouri "Kogoro Mouri") often solving cases along with [Conan](/wiki/Conan_Edogawa "Conan Edogawa").[](#cite_note-A-1) His rank is lower than inspector Yokomizo's.
## Personality[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=2 "Edit section: Personality")]
He is an obedient, but rather slow-witted detective, since he does follow his superiors' and Conan's orders just fine, but doesn't seem to be able to make deductions by himself. He also questions the validity of Conan's deductions and follows Yokomizo's theory at first.
## Appearance[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=3 "Edit section: Appearance")]
He is a young detective of average weight, with mid-length hair sent to the right and a big nose.[](#cite_note-A-1) He is of average height, shorter than the tall Yokomizo, but about the height of [Rumi](/wiki/Rumi_Wakasa "Rumi Wakasa").[](#cite_note-B-2) He wears plain clothes, but without the jacket since they're still in a very hot summer.[](#cite_note-A-1)

## Plot overview[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=5 "Edit section: Plot overview")]
### Beach House Murder Case (Manga: [1098-1099](/wiki/Volume_103#Beach_House_Murder_Case "Volume 103"), Anime: [1148-1149](/wiki/The_Detective_Boys_and_the_Two_Leaders "The Detective Boys and the Two Leaders"))[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=6 "Edit section: Beach House Murder Case (Manga: 1098-1099, Anime: 1148-1149)")]
Shortly after the murder of a beach house manager, Yokomizo, Tsukumo, and the forensics team arrive at the scene and quickly analyse the body. Conan then interrupts them and corrects them, and Yokomizo introduces him to the young detective. He assists the interrogation and runs a few errands to check details with forensics. Before they can bring the framed suspect away, Conan interrupts them and deduces who the true culprit is, which impresses him. After the case is solved, he and the police leave with the body and the murderer that just confessed.
## Relationship analysis[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=7 "Edit section: Relationship analysis")]
### Sango Yokomizo[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=8 "Edit section: Sango Yokomizo")]
He has a high respect for his superior [Yokomizo](/wiki/Sango_Yokomizo "Sango Yokomizo") and believes what he says, even following with his eyes to see if Kogoro was there just as the former said. Since he is probably still in training, he follows Yokomizo closely.
### Conan Edogawa, Ai Haibara, and Detective Boys[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=9 "Edit section: Conan Edogawa, Ai Haibara, and Detective Boys")]
He at first questions whether [Conan](/wiki/Conan_Edogawa "Conan Edogawa"), [Haibara](/wiki/Ai_Haibara "Ai Haibara"), and the [Detective Boys](/wiki/Detective_Boys "Detective Boys") actually are detectives and even suggests that they should leave the premises. After the deduction show, he is rather impressed.
### Subaru Okiya[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=10 "Edit section: Subaru Okiya")]
### Rumi Wakasa[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=11 "Edit section: Rumi Wakasa")]
## Name origin[[edit](/wiki/index.php?title=Detective_Tsukumo&action=edit&section=12 "Edit section: Name origin")]
His surname, Tsukumo (九十九), literally means "99", and is found more commonly in Hiroshima and Tokushima prefectures.[](#cite_note-4) His name is a reference to the fact that the Yokomizo brothers have numbers in their name: Sango sounds like "3-5" and Jugo sounds like "10-5", thus a joke can be made that "3x5" (Sango) equals "15" (Jugo). The kanji for Tsukumo (九十九) are similar to the kanji for "[multiplication table](http://en.wikipedia.org/wiki/multiplication_table "wikipedia:multiplication table")" (九九)[](#cite_note-5).
