Ayano

Stolen out of the nest by a large bird when they were little, Ayano and Azami had always been a pair ever since they defeated it. For the first few years, they had roamed the infected lands of their deity, surviving how they could. Eventually, they learned of the world beyond and left their home, later discovering technology and the things it could do. Azami had been born blind, and her bother, being a Coatl, might as well have been deaf. The prospect of correcting both these flaws seemed promising to them, and they joined an experimenting lab. It was a mistake. While Ayano gained the ability to properly hear dialogue, Azami's eyes were rendered completely useless, and whatever sight she had, even light and movement detection, was gone. The two decided to leave, turning their backs on technology. They later learned of the Holy Trinity of organizations. Distrusting of all three, the siblings keep to themselves.

A few notes:
-Azami was not completely blind when she hatched. She could see movement and light levels, but that was all. After the lab, she cannot see anything. As a result, she relies entirely on her other senses.
-Ayano had normal Coatl's hearing until the lab. Now he can hear as another species would.
-Both of the siblings' sight were based off of their natural eye types. Ayano sees a wider range than normal dragons as per the horizontal pupil.
-Having mostly bad experiences with tech and scientists, they don't trust PROJECT and FL/GHT's mecha members, and they won't side with Unity because, while the organization is against tech, the two figure they'd have to deal with many more dragons than they'd feel even remotely comfortable with. And so they stick to themselves and more... traditional means of fighting.
