I'm absolutely headcanoning Yoriko as having a kid alongside Touka instead of 5-6 years later
Touka and Yoriko could then raise their kids together, learning and sharing as they go
Along with Miza's eldest son Shiroi, the kids could form a friend trio:
A ghoul, a half-ghoul, and a human
To parallel the trio of Touka / Kaneki / Hide
Plus with Yoriko's kid's surname being Kuroiwa, that gives a perfect nickname of Kuroi to match Shiroi
