鴨乃橋ロンの禁断推理

Totomaru Isshiki is a bumbling rookie detective about to be dropped from a stalled serial-murder case when he crosses paths with Ron Kamonohashi, a brilliant private investigator whose license was revoked five years earlier over an incident called the Bloody Field Trip. Ron carries a dangerous compulsion: hearing a killer confess sends him out of control, and he pushes them to take their own life. The two strike a bargain in which Ron solves the cases, Toto takes the credit, and Toto keeps him in check.
