I am thinking she doesn't live with her grandma. I was thinking more along the fact that she doesn't feel like she belongs there so what she does is travel around, kind of like a wanderer and goes from place to place to see new towns or worlds cause she is about old enough to start living alone. I figured that every once and awhile she visits her grandma since she is the last of her family plus it is the only place that was her home for a long time even if she didn't like it much.
Your not prying, just giving me a challenge on working out more of the mystery that is Aruna. Lol I like to not put detail sets into my characters so they can grow naturally like just now XD
