Why everyone is guessing that Kuroda could be Tsutomu?
Honestly I don´t see any resemblance, facial features and hair are completely different, nor the eyes, not even the skin color:
The only character thas has appeared in DC that looks heavily like Kuroda for me it´s Atsushi Miyano:
I know that the theory of Elena Miyano and Atsushi being alive is so unpopular in the fandom but honestly I don´t understand why it is.
For me Hyoue Kuroda is a strong candidate to be Atsushi Miyano, the resemblance is big and also the fact that Kuroda suffered an accident. The only face feature that differs are the eyebrows, which obviously could have been affected by the trauma of the accident. The face structure and the beard is really similar and they both wear glasses, the skin color is also pretty notable. Another point is the relationship with Rei, we know that Rei knew Atsushi when he was little and from the narrative point of view it would make much more sense this relation. For me Bourbon collaborating with Tsutomu Akai seems so vague.
The first encounter with Haibara: Ai looks scared when she sees Kuroda for the first time, but after that she confesses Conan that he just looked a bit scary (this reminds me of some japanese animes of father that is disappeared for a long time and then the son/daughter sees him as a scary person at first sight. Haibara also considers Rumi Wakasa to be a good person, why so? Well because Rumi is a perfect candidate to be Elena Miyano.
The resemblance Rumi-Elena is also really notable, Yamamura also mentions ¨hell angel¨during 1033 case to Rumi. But for me the strongest point was in the Hatoyama Farm case , how Bourbon somehow recognized someone familiar in Rumi, and she also did. Rumi is an intelligent person that also has the APTX list for some reason.Also she has some scars that evidence some accident or a torture.
On the hand I really think that something happened in the
case from 17 years ago that involved Elena and Atsushi. Their ¨disappearance¨happened really in the same year, when Haibara was just a baby. Elena is the sister of Mary and this shoulnd´t be something just to say oh no Akai dated his cousin! I think at some point they collaborated on trying to destroy the organization and in that plan Kohji Haneda, which was friend of the Akai family, was part of it.
My bet is that MI6 somehow discovered that Amanda was about to meet someone really important inside BO. I think Amanda was fundraising Karasuma Group because she was looking for something close to the eternal youth, but she also knew so much about it, so Rum´s plan was to have a reunion with her and offering her the silver bullet drug that the Miyanos have developed to eliminate her. Of course, Amanda previously chatted with Kohji and probably she talked too much about The Karasuma Group, hinting that she was about to meet with casually, one of the shogi players in the competition: Chikara Katsumata - Chikatta Karasuma, Rum.
I think Elena perfectly knew that the drug that she developed with Atsushi was deadly, and after having a conversation with Kohji they must have developed some plan. Elena probably just wanted to avoid at all cost Amada to die with her own drug but she was too late. I really think that Elena took Asaka´s place , but now in the way we think. I really think that Asaka was Mary but the one that was heavily involved in the case was Elena. I think Elena saw Rum and understood that Amanda died from the drug (with no violence because she took it herself in front of Rum). Elena probably saw Rum and then what happened is not so clear for me, but I think Rumi/Elena says that Kohji is an idiot because he challenged so foolishly the BO, just as Haibara acts with Conan when he things on challenging BO. Elena/Rumi feels heavily guilty that Kohji died from he own drug. My theory though is that was Wakita/Whiskey who went to kill Kohji, but Kohji knew that Chikara was a Karasuma and that he was in that shogi tournament to kill Amanda.
For me this is a strong theory in the sense that the Miyanos have been mentioned a few times during the arc, even showing the case of Bourbon´s flashback. Why is so important to link Bourbon to the Miyanos? Why is important for the story? For me it would make perfect sense that they are alive, and moreover give to Haibara a proper happy ending. On the other hand, they are the only ones that can develop the definitive antidote to the APTX effect, Haibara has really tried but only temporal solutions and at this point I think we should expect a miracle, the series are not going to end saying..and then Haibara developed 2 years after an antidote...for me it would make more sense if the Miyanos, alive, created an antidote for Conan in the final battle against BO, and then surprise Haibara.
Some people may think it´s a bit crazy but if you think on it it doesn´t seem that crazy, it´s a good way to run towards a really epic end of DC, for me Atsushi and Elena are just so important characters to leave them dead on an ¨accident¨, fake accidents have been so common through the series and we know that there are a lot of traitors in BO that could have just have saved the Miyanos, maybe somehow Tsutomu Akai was involved in all this operation. Maybe the Miyanos were meant to be killed but Tsutomu arrived on time to save them, probably Atsushi was worst injuried in the accident and that´s why the coma. Thinking in how cold Mary and Ttutomu behave, most probably they told Elena that Atsushi died.
For me is not really clear what has Elena done through all this years, but for sure seeking an extreme revenge towards BO. I wouldn´t be surprised that Mary told her that Akemi and Haibara were murdered, because then Elena would have fought till she could recover her children. Left without any hope most probably she felt on depression and became protected by MI6. However, she must have been reactivated when Akemi Miyano or that bank robber isis found death and discovers that actually that person was her daughter. Moreover, by what happened in London, discovers this little boy called Conan and wants to get closer to him.
For Atushsi is more unclear, most probably he spent those years in comma and then he bacame superintendent thanks to some contacts related to the Akais, which is clear is that he probably recognized something familiar on Rumi, my bet is that he just thought that Rumi is Mary, and Mary was meant to be Asaka in the original mission of 17 years ago.
It just surprises me how many people believe that Tsutomu Akai is alive and not the Miyanos, yes, Gosho once said that the Miyanos are death but we can´t trust Gosho´s word, not after this Rum arc. Do you seriously think that Gosho would reply to that with a ¨Look forward do it¨. Manga series are meant to surprise xD
