Question of the Day!
Has your Warrior of Light ever used a Fantasia? Alternatively, are they considering it? Tell us about that!
None of them have ever seriously considered using a Fantasia, all for relatively similar reasons. (I will note that given Headcanon reasons they all have very different builds than what their in-game models represent -- Mirita is probably at least 5'7" or 5'8'", Khorijin is an inch or so shorter than that, Rija is taller than both of them, and all of them have much more muscled builds than the game allows; Mirita's is the thickest and Rija's is the slimmest.)
Mirita understands why people would want to Fantasia, actively encourages it for anyone that expresses a desire for it, and has gotten Fantasias for people who want them, but even when she didn't know what her parents looked like, she figured she was the last living remnant of her parents, and doesn't want that to vanish from the world.
Khorijin is very happy about how much she resembles her mother and wouldn't trade that for the world. At most she might have wondered about doing it for eye color purposes but is also kind of happy with how her liminal rings do a good job at glaring holes in people.
Rija, similarly, likes how much she looks like her sisters and her mother.
