Kiei tilted her head and considered Aurora's view on 'ground-dwellers', "I suppose in a way you are right; most 'ground-dwellers' are the same with desires for power and such. What makes nobles worse is the fact that they have the money with which to gain the power they want in any way that they want... normal 'ground-dwellers' may wish for power but most can't really do anything about their situation without money or the ability to fight... does that make sense?" she really wasn't very good at explaining things and had most likely just confused Aurora more with her attempt.
"As for being a criminal... well I wouldn't say that i've necessarily done anything worthy of the title... it's complicated but the society I come from is full of complex rules and if you break too many of those rules you are considered a menace to society and the safest way to deal with you without killing you is to imprison you for life. So basically I broke a lot of rules when I left which is why I can say with certainty that I wouldn't be welcomed back with open arms if I were to return" It would take Kiei hours to explain the complex society she had come from and even longer to then list the rules she had broken and how; they would seem petty things to pretty much anyone who had never been to Risoukyou and certainly not worthy of life imprisonment. So she hoped this explanation would ease Aurora as she had noticed a slight change in her demeaner when Kiei mentioned she was technically a criminal.
"So there are two different polar lights? Of different colours? This is something I hope to see one day, it sounds fascinating! But I wonder at your not feeling emotions before, in some ways that could be viewed as a blessing and in others something to pity as love and happiness are wondrous things". Kiei wondered like Aurora whether she really would feel emotions differently to those who were born naturally with them, but then it was hard to tell if anyone felt emotions in the same way; just like looking at a color and knowing it's pink, another person would also call it pink but would you both be seeing the exact same colour in the exact same way?
