A beautiful loving and passionate woman. Is always there when you need her, isn't the type to love and be let down. She has a way about her that every woman wants. She won't love hard but one time, some men are lucky enough to have a woman as wonderful as she is.
I love my Isis.

This is a girl with many talents! Isis is a pretty and funny friend. If you meet a girl named Isis.....try to be her friend. She will always have your back.

Letting Isis go won’t be a good thing for you. She is loyal and just the legit best! Don’t get on her bad side! She can fight and won’t let anyone hurt you. Isis is normally tall for her age and is always in good shape. People may mistake for a rude person but if you get to know her you will LOVE her!
Isis is funny
