Ultimate Detective

Ultimate Detective, called Super High School Level Detective (超高校級の「探偵」 chō kōkō kyū no “tantei”) in the Japanese version is a title given to multiple people in Danganronpa series.

Overview
Ultimate Detective refers to Kyoko Kirigiri, Shuichi Saihara and Kumaichi Suzuki. Although they have the same talent, their personalities and their detective skills are different. Kyoko, in Danganronpa: Trigger Happy Havoc, is stoic and reserved about her feelings, not wanting them to affect her cases. Shuichi, in Danganronpa V3: Killing Harmony, is calm and timid, and claims that he solved his cases due to luck. Kumaichi, as a Word of God only character, has little description, however supposedly is a hard-boiled, meaning firm willed, but playful, detective. He had already graduated thus earning the title Former Ultimate Detective.

It is mentioned in Danganronpa V3: Killing Harmony that in past games, the Ultimate Detective has never been a murderer, implying that there may have been more unnamed characters with this talent.

Skills and Abilities
Both Kyoko and Shuichi are shown to have impressive deductive skills, often being able to notice details that other students overlook and on occasion being able to identify the culprit even before the class trial begins. However, they don't always reach the correct conclusions; for instance, during the Killing School Life, Kyoko incorrectly speculated that Mukuro Ikusaba was the mastermind behind the killing game. Nevertheless, Kyoko and Shuichi are often essential to solving not only individual murder cases, but the greater mysteries surrounding Hope's Peak Academy and the Ultimate Academy for Gifted Juveniles. Not much is known about Kumaichi's skills, however as a Former Ultimate Detective it is to be assumed he has some great skill as a detective.

Employment and Talent
As detectives, all three are employed however each work for a different agency. Kyoko works for the Detective Library where she gained a Detective Shelf Collection number of DSC 910 (the highest proficiency in Impossible Crimes), which helped get her scouted into Hope's Peak Academy. Shuichi works as an assistant at his uncles private detective agency, and once by chance managed to solve a high profile murder case faster than the police, earning him the Ultimate Detective title. Kumaichi works for a mysterious master, whom he allows to ride on his back like a horse, however it is unknown what earned him the Ultimate Detective title, but given his middle age it likely was not related to the Detective Library.
