Reiko Kujo/Relationships

Conan Edogawa
Reiko Kujo's Acquaintance. Reiko has often noted that Conan has a keen sense of observation, complimenting him during a check out on the crime scene for their next trial. Unaware of Conan's extraordinary skills as a detective, her conclusions have always been foiled by "Sleeping Kogoro" thus resulting her consecutive defeats in her confrontations with Eri.

Eri Kisaki
Reiko Kujo's Rival. Ever since her first encounter and confrontation with the Eri, Reiko has been determined to beat her winning streak and thus further her reputation. However, despite her consecutive defeats against Eri, Reiko vowed to someday defeat the "Queen of the Courtroom" who has never lost a case with the help of her Secretary, Sasaki, whenever a chance would present itself. Reiko respects Eri's skills and deals with her on a strict professional basis. Despite their intense rivalry, Reiko would cooperate with Eri if it means on bringing the culprit to justice.

Midori Kuriyama
Reiko Kujo's Acquaintance. Midori Kuriyama is Lawyer Eri Kisaki's Legal Secretary and has confronted both Reiko and Sasaki several times in the court.

Takeshi Nezu
Reiko Kujo's Former Superior. At some point, when Reiko was still employed in the SID (Special Investigation Department), she joined forces with her superior to investigate the political level bribery involving Takeuchi Construction Company.

After spending the effort on investigating various keys related to the Takeuchi Construction Company's Scandal over some defective townhouse construction work, the Key Deponent of their Case which is the Company's Construction Design Manager committed suicide thus turning the case complicated. Should the suicide have been prevented, the both could have resolved the case on his testimony. However, he suddenly changed his story entirely, leaving them no choice but to cease the prosecution.

Eventually, Reiko's Boss was reassigned elsewhere in Tottori and Takeshi started to live their together with his wife, Kayoko. He then died two years later, at early December.

Kogoro Mouri
Reiko Kujo's Acquaintance. During Reiko's first confrontation and trial against Eri, she cleverly turned Kogoro into a Prosecutor's Witness as she knew that his testimony would support her conclusions instead of Eri's. However, her plan to further use Kogoro backfired when Conan tranquilized him and revealed the truth through "Sleeping Kogoro".

Reiko and Kogoro would often meet several times whenever examining crime scenes related to the Prosecution. When Reiko compliments Conan about his keen observation, Kogoro would always contradict her as he considers all things observed by Conan as useless.

Ran Mouri
Reiko Kujo's Acquaintance. Unlike Conan/Shinichi, Ran has only heard little about the Prosecutor. Whenever Reiko performs in the court against Eri, Ran would often watch the intense battle between the "Madonna of the Prosecutors" and her mother, the "Queen of the Courtroom".

Sasaki
Reiko Kujo's Legal Secretary. It has been clearly hinted that Sasaki is infatuated with Reiko. However, it is currently unknown if she reciprocates his feelings.
