She is very intelligent, yet cynical. She may be seen as "nerdy" by some, but she takes pride in having that title. As her name applies, she is a good person with numbers and equations, but that's not all: she always has a backup plan with her whenever she needs. Although smart, Nabla can become easily irritated and bossy towards her team, in special to Alef (her cousin), who is always picking and mocking on her because of her (in his words) "nerdy" attributes.
