@Siquall Instead of the father, it's their father's father's fault. It's because of him that their father turned out to be a bastard. But it might just be their father's father's father too.
@HiandHello it has to be, because the most thematically significant way to end this with Migen is to have Nine do it, especially now that the story has gone out of its way to especially setup how meaningful it is for Nine to see Migen again -he needs to be the one to beat Migen, for his character arc and for the significance to the story
