Five years ago, Ron was the top student at the Detective Training Academy Blue. However, after being found responsible via temporary insanity for a deadly incident known as the "Bloody Field Trip", his detective license was revoked and he was expelled. Unable to fulfill his only love of solving mysteries, Ron has lived in isolation since. When Totomaru seeks his help on a case, the two form a partnership where Totomaru takes the credit for the cases that Ron solves.

Stage play

A stage play adaptation ran from November 1–4, 2024, at the Nippon Seinenkan Hall in Tokyo, and on November 9 and 10 at the Sankei Hall Breeze in Osaka. It was written and directed by Keita Kawajiri, with music composed by Futoshi Arai.

Reception

In June 2021, Ron Kamonohashi: Deranged Detective was nominated for the seventh Next Manga Awards in the Best Web Manga category and placed 14th out of 50 nominees. The series has been recommended by mystery writers Rintaro Norizuki, Masaki Tsuji and Sako Aizawa, all of whom have topped the Kono Mystery ga Sugoi! list. In a blurb, Aizawa called the series an "authentic mystery manga for the new era" and praised its fast pace, as well as the tricks and logic used to identify the culprits. Ryoko Fukuda of Real Sound compared the relationship between Ron and Toto to that of the straight man and funny man roles in manzai comedy, and said she was looking forward to how the "pop, fast-paced story" would develop.
