Yukari and Hana look nice as I expected as adults. Their parents looked great for their age. Miho looks just like her mom but without crows feet and dark hair.
Miho's mom looks nice too but its hard to want to stay near a woman that glares at everything when she wakes up in the morning.
I guess Miho become the patriarch of Nishizumi Family instead her sister
I'd honestly picture Miho to be starting off a Nishizumi Style offshoot in Oarai rather than be a proper successor, considering no one's contesting the firstborn to succeed the family business, least of all Miho and Maho themselves.
