Analysis of the relationship between Shiho Miyano and Gin sake
First of all, the origin of this idea is because Aoyama Sensei responded that Miyano Shiho and Gin sake are related, but the specifics are not clear. First of all, because of the picture below, I initially wondered if it would be a relationship like a lover (every time Gin would think of Sydney, it was this naked back).
But this idea is overturned, because it is only a means of expression, which means that someone is completely seen through. And Aoyama-sensei said that Gin wine will not fall in love with anyone. Then there is the fact that Gin sake should be about 30-40 years old, and Miyano Shiho is 18 years old, and there is currently no such age difference between nako and nako.
That excludes this method, and can only proceed from other aspects. Gin is the brother of the Organization Officer, and Sydney has been in the Organization since she was a child because of her parents, and her parents died at a very young age. Then after this, her only relative should be her sister Akimi Miyano. And through Amuro's memories of his childhood, he and Mingmei were playmates at that time, so they should be similar in age. Toru Amuro is 29 years old, and Shiho Miyano is 18 years old, and they are 11 years apart. Combined with Amuro's memories from his childhood, he learned that Mingmei's mother, Miya Elena, was pregnant when he was a playmate with Mingmei as a child. So since Amuro and Shiho are 11 years apart, and Mingmei Amuro is similar in age, Mingmei should be about 11 years old when Her mother is pregnant.
Back to the main topic, Miyano Shiho's parents died when he was very young. Suppose her parents died when she was two or three years old, then her sister Akimi Miyano was only 13 to 14 years old. It is unlikely that Mingmei will fully have the ability to make money to take care of herself and her younger sister at this age, and because of her parents' work for the Black Organization, it is speculated that Mingmei stayed in the Black Organization at that time (similar to the Black Organization not letting her go).
So if that's the case, then the Miyano sisters should have grown up in the Black Organization. But Miyano Akimi was still so young at the time, and according to the plot, we can also know that Miyano Akimi was not a big color in the black organization, so even if she could give Miyano Shiho care spiritually, she should not be ideal in terms of living materials. And Miyano Shiho is a genius scientist, studying in the United States, it is not difficult to guess, it is tissue culture.
Then at this time, you can bring out the gin. First of all, from the essence of gin wine, as the main cadre of the black side, his decision-making ability is naturally very strong. So I think it makes sense to plan to train Miyano Shiho. Because Miyano Shiho's parents are medical personnel, Miyano Shiho is their child, taking over their tasks is the most ideal choice, besides, Miyano Shiho has a high probability of inheriting the wisdom of his parents.
It is also true that Miyano Shiho is a genius, and he received a doctorate at a young age. Thinking further, if Gin sake intends to cultivate Miyano Shiho, will there be other intersections in normal times? I suppose, perhaps like an elder caring for a child, Gin watched him grow up.
Gin no longer has any relatives in the world, and Miyano Shiho's parents died shortly after birth. I think they're kind of similar to each other, they're all lonely people. So since there is something in common, Gin takes more care of Miyano Shiho, and it is clear that he cares more.
