The Yasuhisa sisters were considered failures, and it’s been bothering me for a long time. They were clearly functioning fine, but with the recent chapter’s closeup of Kurona/Their eyes, the marks below their eyes are a dead giveaway:
They’re scars from surgical staples, aren’t they? Leftover reminders of being human, like the scar on Keneki’s abdomen.
This leads me to believe that their bodies went through a period of rejection, which ultimately lead in their kakugan’s inability to activate. The ones they have now must be donors.
PS- I think this is Kurona imagining herself as one with her sister.
The angle of the “camera” is off too much, and the speech bubble acts like more of a divider than anything. There’s just no need for another eye transplant, unless Kanou was trying to fool someone, since her RC count is already high enough.
But what did Kaneki have that they lacked? He didn’t need an eye transplant, so why was he, a prototype, more successful than the real deal?
The answer is RC cells. Rize stabbed him through the abdomen, so not only did he receive Rize’s kohakou, but her kidney as well. He had a much bigger immediate boost in RC’s than either Kurona or Nashiro, and his body was able to accept the transplant straight-off. It probably helped that the kidneys– organs responsible for regulating fluids within the body– are located directly next to his new rinkaku, too.
So here’s the problem regarding the other two synthetic half-ghouls we know of, Takizawa and Amon. We don’t know much about their surgeries– even less about Amon in general.
They were purely human, and so one of them had to have a boost in RC cells in order for my theory to stand (especially after losing so much blood during the raid). So I found a little connection here that might have something to do with it:
