the two kagune exploded when close to each other, just like it happened for Amon and Seidou back in ch114/ch115 and they were both grafted with Yoshimura’s kakuhou themselves.
Hi! No worries Anon, your English is perfect 😀
Actually it doesn’t mean much as it is, it’s just that it was a theory that many in the fandom
had
for a while…
and now it seems it’s confirmed that Saiko’s Qs surgery was done using Kaneki’s (or maybe Rize’s) kakuhou.
Otherwise, it also seems to imply that if two absolutely similar kagune (as in, kagune produced by copies of the same kakuhou grafted in different individuals, like Amon and Takizawa as another example) face off…
&
then it goes boom.
The how and why aren’t clear yet for me right now (I’m thinking maybe it’s some sort of strong cell attraction or repulsion between similar cells and, when they collide or that the repulsion force becomes too overwhelming for them, it liberates enough energy to create an explosion), but I don’t doubt that other fans may come up with something that makes more sense, before Sensei explains why it all means. 🙂
I hope it helps, have a nice day Anon!
Anon-chan, blood types were never confirmed to have anything to do with whether or not a kakuhou graft would be successful. :3
It’s also something people theorized about for years because Rize and Kaneki were both AB types, but for now, there is no correlation as far as we know, so it doesn’t matter whatever Saiko’s blood type is. 🙂
