I agree, I think all Kirana should be obtainable in game somehow. I just think there is a definite possibility Kirana would be sold.
I know many games sell mounts... so would mounts in here also be considered Kirana? Because if so I'm pretty sure those would be sold, but maybe they would only have abilities for travel so that would be ok.
Thats a good question actually, my guess would be big kirana will be mountable, and small ones not
