They can meet in Kelan, sure. We can say Momo already asked the king of her country.
I don’t know how much they’ll get exactly. But Hecotoro-Sensei can use it in the plot however he likes.
(I assume they’ll be left at home for this season, merely because of the villain designing problems previously mentioned.)
By the way, if someone wants to make Wind, they can. I haven’t really had time to flesh out that one, and idk when I will.
