If kahaku or whatever his name was died before he had kids then how tf did their hayase's ...

they are like an entire cult bruh
kahaku is not the only crazy bitch bloodline

Yah but how did the knocker in his left hand, still exist in the current girl from their bloodline?

Prob all the decendants have a little bit of root in them

Idk maybe he has uncle or some aunts

But, Kohaku himself was adopted right? How can their be somebody like uncle or aunt? In fact we can say maybe that left-hand knocker is sharing gene instead?

yeah from understanding this. knockers cannot be separated or spread out/ distributed from it's core part and still have a brain of its own, because of this, you're unable to spread the knocker to fellow family members. so when kahaku killed himself and the knocker he was able to fully remove it, unless the knocker took over, survived then made kahaku bang someone that looked like fushi.

I need to reread this, from what I remember,
all the cultists have a knocker on their arms.

or it might also be from my theory that what the girl is doing is just acting like she had a knocker and killed her mother for kicks

i think its your theory tbh or this manga has a plot hole.

Lol right? I also asked this before but still unsatisfied with the answers.
