Isby 

a cute intelligent girl with a ditsy personality. Tries to get away with everything with an innocent smile or giggle. At times she can be passive but stands up and holds her ground when it comes to issues she truly cares about. definitely a lady in the streets but a freak in the bed.

Isby is the kind of girl you want to marry.
