The 2nd daughter of Cat and Vei, Ash is 12 years old, blind, and uses a spear. Unlike her sister Hannah she takes more after her father, even having her own demon form. Despite her naive nature and blindness, she's not stupid and it very useful in combat. 

She should sound like a girl that is around 12-13 years old.
