It was a pretty fair question, really Stolt...I would've told you to ask the CR why they accepted her, but it looks like Summer already gave a response. xD
Anyway, her desertion from Liberty is something that the Colonial Republic didn't reeeeeally find out a whole lot about until -after- Arisu was enlisted in their military. Way I see it though, it doesn't -really- matter to them because they're not exactly really close "friends" with Liberty or anything like that, so as long as Arisu is willing to serve the Colonials, her past probably doesn't really matter too much to them.
To be fair, everyone has to come from somewhere, and if all our characters had 'normal' backgrounds then things would be just as boring as if all our characters had "super awesome badass" backgrounds.
To be fair, even the Liberty Navy [LN] is filled with a fair few "misfit" characters, in addition to all those with semi-regular backgrounds. I like it, I think it makes things interesting.
