What if Shiro is really the twins’ father?
I’ve seen the theory going around before, so it shouldn’t be a new idea at all, but frankly the more we get into the flashbacks the more I wonder about how likely it could be.
So here’s my take on it: it was said in the story before that Yuri became pregnant with the twins because she was impregnated by Satan’s host, which means that the male human who Satan possessed could also be called the twins’ father.
Thanks to Lightning’s recent investigation, we were kinda pushed to believe that


Azazel’s clone #5 Goro was The One, but who knows for sure, especially since looking at Yuri…

…there definitely was a thing between her and Shiro.
Furthermore, the newest chapter told us that Shiro was the only one who made it Exwire amongst the Azazel clones and we know it was also the case for Yuri since she eventually became an exorcist.

So I just wonder how Yuri would have come to meet with Goro who was probably a permanent resident of Section 13 in the first place, unlike Shiro with whom there definitely was a closeness for years because they were both trained to become exorcists.
Then again, you could argue that Yuri didn’t have to know or love Goro for the twins to be conceived: I mean, there is the horrible eventuality that she was raped by Satan possessing Goro or even the anime’s take on it (especially if Shiro never gave into his feelings for her and kept pushing her away).
It’s just…I think that the idea that Shiro could be the twins’ biological father is interesting because he is similar on different aspects to both Rin and Yukio, as Rin himself mentioned in the newest chapter.
At the same time, the idea that he raised the twins simply because of his love for Yuri is absolutely beautiful too, but it can still work because Shiro wouldn’t even have to know/believe that he’s actually the twins’ biological father in this theory. I mean, look…

when he possessed Shiro in the very first chapter, Satan was the one in control of Shiro’s body, until Shiro managed to overcome him at the very end.
My point is that the same could have happened in the past: maybe Satan possessed Shiro for a very short while, had sex with Yuri (who was in love with Shiro for a long time and didn’t notice anything?) and that’s how the twins were conceived, with Rin inheriting Satan’s powers.
And when it comes to Goro, either Goro was the first human ever possessed by Satan, which is how he gained an ego and started possessing other humans, leading to the twins’ conception (through possessing Shiro) and eventually to the Blue Night as we all know, or Goro’s possession was simply the start of the Blue Night and that’s why his file is gone.
EDIT: btw about the blue night I still think that Mephy managed to save the day by promising Satan to give him Rin’s body once Rin would be old enough. Not only did Satan imply so but Lucifer wouldn’t kill Rin also for this reason.
It’s just a theory obviously, but I really hope the flashback will tell us how Yuri could even know Goro since she probably never found out about Section 13.
If we know that, then I guess we can rule out Shiro from being the twins’ biological father, but not before.
Last point, but Mephy once mentioned that if Yukio was the one finding out about the past the way Rin is doing right now, it wouldn’t bring good results…


…and since Yukio already believes that Shiro was just raising them as weapons to take down Satan, I can’t even begin to imagine what’s really the twist behind the twins’ existence that finding out about the truth (which is what Yukio wanted for so long) would make Yukio feel even more horrible…
EDIT: I guess that if the Grigori have it wrong and Satan didn’t possess any guy (Shiro or other) who then had intercourse with Yuri, resulting in the twins’ conception, the other possibilities are that:
- Satan possessed Yuri herself and that’s when the boys were conceived (kind of similar to the Virgin Mary)
- or that Yuri was already pregnant (because of Shiro? or another guy?) and Satan possessed her during the pregnancy, leading to the twins getting powers and becoming interesting vessels.
