Do you think we'll get to see an older Riju in Tears of the Kingdom? In the leaked art book, that I shared and can send the link to anyone else that wants it, it does seem like there is some Gerudo woman shown from the waist down who looks smaller than a normal Gerudo woman but bigger than Riju in Breath of the Wild. She has a new dress design as well, which was the focus of the art.

We certainly see that Purah has aged up to her normal age, but that could just be that she found a way to reverse her anti-aging serum and is aging at a more accelerated rate now or something like that.

Zelda and Link look to be about the same age, but they were already basically at adulthood while Purah and Riju obviously were not. Paya looks a decent amount older in the concept art of her too, but Impa is shockingly still alive so not THAT much time could have passed.
