I suppose Ashe does have to be quite young, as the idea behind her story feels a bit like 'a huge amount of power and responsibility coming into the hands of someone not quite experienced enough to be certain of what to do with it' to me, but I agree; early-to-mid twenties, perhaps, but she doesn't feel nineteen.

Those characters certainly do look older than the typical female Squeenix design. Hooray! Thanks for the examples; it's good to know that characters like these exist.
