In chapter 172, Ron finally confronts the Moriarty family head-on. The culprit behind the elaborate trap targeting Ron is revealed to be someone who was once his mentor. Analyzing the faint scent of perfume at the crime scene, Ron deduces that his opponent is a genius toxicologist and swiftly prepares an antidote. Toto mocks him, claiming Ron will never be able to solve a case again, but Ron responds with a fearless grin, completely dismantling that notion. By manipulating the "sound" trick the culprit set, Ron forces the accomplice to confess via a hidden microphone. The story hits a climax where the history between Ron and Toto interweaves. The profound loneliness and resolve in Ron's eyes reveal him to be a warrior pursuing truth rather than just a detective. In the final scene, it is hinted that the next target is a friend of Toto’s, pushing Ron into an unprecedented predicament.
