The protagonist of this work is a third-year middle school boy who aims to be a famous detective. His academic performance is average, his language skills are not good, and he doesn't know how to swim, but his reasoning ability is outstanding. The reason why Q wanted to become a detective was because he was rescued from a kidnapping by a criminal group by an "uncle detective" when he was six years old. The "uncle detective" later gave Q a notebook of his detective experiences. As everyone knows, this "Uncle Detective" is his father "Liancheng Xiao". He has a happy-go-lucky personality, but he becomes serious when a case occurs. He was a bit lustful, and was often punched and kicked by Hui for seeing her "upskirting"; in addition, he and Kinta once peeped on women taking baths in a hot spring hotel, but in the end they were discovered by Hui and kicked and kicked by Hui. The watch he wears on his hand often stops for no reason, which often causes Q to mislead the time. His famous sayings are "A detective who cannot persevere will make the truth sink forever!" (Also translated as "If even the detective gives up, the case will be trapped in a maze forever!"), "There are (number) hints! ( instructions). And there’s only one answer!” However, these lines are often borrowed by companions and become the signature lines of this game. Finally, he becomes Megumi's boyfriend in the final chapter of the manga.
