"If everything goes to plan, there should be no reason for us to linger longer than needed. I doubt Aria will be staying until the realm is destroyed so the moment I see her, I'll be able to leave and track her down at a later time." Shiro reassured.
In order to track someone down, she needs to see the codes of the area and where they've exerted their influence. If Aria does indeed run away, finding her through the myriad of worlds would be a difficult task if not for the fact that she could use the Beyond as a gateway. She'll be able to scan every world to find where Aria is.
'As long as I see her once, there'll be nowhere for her to hide.' Shiro thought to herself with narrowed eyes.
