As a detective reasoning anime, "Detective Conan" is dead in every episode, but these people who die are basically victims of the case, and not many characters really related to the main plot die. For example, Shuichi Akai, although he once died in the work, but it did not take long to "come back from the dead", and he also had a new identity, Okiya Pleia.
Speaking of "resurrection from the dead", "Detective Conan" author Tsuyoshi Aoyama also mentioned in an interview, but someone asked him if there would be anyone in his work who would "come back from the dead" like Shuichi Akai, and Aoyama's answer was also very simple, yes, but it could not be said for the time being. Judging from Aoyama's answer, there will definitely be a dead person in the later plot who will appear in the plot again.
For this character who is about to "come back from the dead", fans are also speculating about his identity. Personally, I think there are two characters that are most likely, the first is the father of the strange thief Kidd, the previous strange thief Kidd, kuroba thief one, and the second may be the father of Shuichi Akai, Makoto Seiryo, and Hideyoshi Haneda, Akai Takeshi.
These two characters are in a state of "death" as soon as they appear, but no one in the plot can be sure that they are really dead, and they belong to the type of living and dead. Moreover, these two are related to the main characters of the work, Kuroba Thief is the father of the strange thief Kidd, and Akai Takeshi is not only the father of Akai Shuichi, but also related to the main plot.
It's just that although Kidd is one of the protagonists in "Detective Conan", he is actually the protagonist of Aoyama's other work "Magic Fight", which is a cameo in "Detective Conan", and his father Kuroba Thief is not much related to the plot. Therefore, it is more likely that the person who "came back from the dead" in Aoyama's mouth is Akai Taketake.
Speaking of Akai Takeshi, he is inextricably linked to the main plot and the boss of the work, the Black Organization, who is an agent of MI6, who was hunted down by the Black Organization for going to the United States to investigate the case of Hiroshi Haneda, and his whereabouts are unknown. Akai's wife, Mary, is also an agent of MI6 and has also eaten APTX4869, and her son Shuichi Akai is an FBI agent who has also been dealing with the black organization.
In summary, Akai Takeshi should not be dead, he may have hidden in order to avoid the pursuit of the black-clad organization, and I believe that he will appear again in the future plot.
