Timeline

This is a timeline of all the events that occurred during the series as well as events prior to Shinichi's reversion into Conan. The years are listed in reference to the current storyline time in Detective Conan.

Detective Conan operates on a floating timeline, which means there is a severe but unavoidable contradiction between the amount of time characters claim has passed and how much time has apparently passed according to the reader. These contradictions make it impossible to realistically determine when certain events in the current timeline happened exactly, since 20+ years of cases, seasons, and holidays are being crammed into "less than one year".

Subaru tricks Haibara into hiding in an empty room, and Conan forces Kaitou Kid to disguise as Shiho. Amuro confronts the disguised Kid and reveals himself to be Bourbon.

• Shukichi Haneda achieves his goal of getting all seven Shogi Titles. His victory for the final title seems to interest Subaru Okiya, and Mary living with Masumi.

• Hyoue Kuroda is re-positioned into the Tokyo Police and takes the place of Kiyonaga Matsumoto, who has been promoted
• Yumi reveals that even if she asks Shukichi Haneda out, he refuses because he is busy. Conan seems to think that it is because he is swamped with interviews from having just earned the last of the seven Shogi titles.
• Masumi inquires if she and Amuro have met before, but he denies it. Masumi mentions that she was taught a few guitar notes by a friend of her brother. Amuro later mentions Masumi's brother's friend as male when Masumi never mentioned that which draws more suspicion to him. Masumi launches into a flashback where she remembers seeing her brother Shuichi and another man. When Shuichi leaves to buy Masumi a ticket, the other man teaches her some guitar notes. Then a third man walks over and calls the previous man "Scotch". Masumi notes that the third man resembled Amuro, but because the man had a hat covering his face, she couldn't tell.
• Due to a bit of unwashed makeup on Haibara's face, Conan begins to think that she might be related to the Unknown child. Because of this conclusion, he wonders about the relationship between Akemi and Shuichi.
• Due to a TV announcement, Yumi finally learns that Shukichi is a shogi champion. Sato points out that he envelope that he gave Yumi could contain a marriage certificate. Since the salary of a shogi player is really high, Yumi desperately searches for the envelope. Due to recently throwing it out accidentally it ended up in the hands of the apartment manager who doesn't seem to like her. She is tasked with figuring out an 8 digit password to gain access to a computer to learn of the envelope's location. At the conclusion of the case Yumi speaks to Shukichi by phone and finds out he has lost one of his titles which makes the contents of the envelope, a marriage certificate, invalid. She also learns that Shukichi has a deceased non-blood brother named Kohji Haneda. Haibara reveals that Kohji Haneda was one of the names on the APTX list.
• Conan searches for Kohji Haneda on the internet and discovers a website where information about Kohji's death, and the death of another individual named Amanda Hughes, has been uploaded. Seventeen years ago, Kohji had gone to America to play in a chess tournament and Amanda, who was a fan of Kohji met up with him. The site states that Kohji's room was ransacked and there were broken glass and cups on the floor and that his hand had signs of gripping scissors tightly. A certain mirror that originally read "PUT ON MASCARA" has been broken so that the only letters that remained were "P T ON", and a faucet had been left on in the bathroom. The site claimed that Amanda's room had been left untouched. Sometime before the incident, Amanda had been approached by someone named Asaka who became her bodyguard. In the present, a similar case occurs and Conan, Shuichi, and Agasa go to investigate. Shuichi reveals that the Kohji case was the case that forced him to join the FBI. At the end of the current case, Conan and Shuichi determine that the "P T ON" must have been Kohji's dying message and that it converts the missing letters "U MASCARA" to "ASACA RUM".
• Conan believes that the dying message "ASACA RUM" means that Asaka is Rum. Kogoro is contacted to appear on a TV show with a "spirit detective" who potentially has more information about the Kohji case. However, when Conan and Kogoro arrive to meet him at his hotel, they find him dead. They also find out that Masumi has moved hotel again and is now living in the adjacent room. Conan manages to get a picture of Mary, but in the process he drops his voice changer. When the case is solved he reaches for it and freaks out when he realizes he doesn't have it. Masumi places her phone on Kogoro's neck and suddenly his voice starts coming out. Mary does the deduction. Conan tries to run out to see who was doing the deduction but Masumi stops him once. The second time Conan makes it to the balcony and finds his voice changer. The culprit tries to run into the adjacent room via the balcony to escape but Conan finds him knocked out. Masumi accidentally lets slip and calls out the name "mama". Later Masumi consults with Mary about whether Conan could be trusted, but Mary doesn't seem to think so. Mary doesn't seem to think that Conan is similar to "the boy we met 10 years ago". The Spirit Detective, Gaito Hotta's information was that be believed Asaka to be a woman. He was planning to have Kohji's ghost say that he was about to be killed by a woman. Supposedly someone also saw Asaka carrying a small mirror with a handle. Conan, in bed at the Detective Agency looks at the photo he took of Mary on his phone and considers the possibility that Mary could be Asaka. Had she been a body guard 17 years ago, she must be pretty tough like a man on the inside, and her age would be pretty high.
