Is your OC a Mary sue?

Angelice -Non fandom OC

Fandom: Original

Name: Angelice
At least its not Angelica
Gender: Female

Creator: @Sun_god_

Age: 235 (divide by ten for human equivalent age)
Hmmm.
Sexuality: homoflexible (straight, but very rarely is sexually attracted to the same gender)

Family: her friends

Appearance: opal coloured eyes, long curly blonde hair, tallish (5'8"), flat chested, beautiful, Crystal wings (wings describe personality. Crystal wings mean that she isn't valuable and she is only a pretty face)
I'd like to see an angel oc with colors that stray from blondes and whites. Also, how can she fly with those wings?
Personality: kind, moderately intelligent, hates being told she can't do something, isn't very special

Likes: her boyfriend, her friends, freedom, open spaces, being alone

Dislikes: demons, the council of gods, being defined by her wings, some of her classmates, her cultures beliefs, her wings

Weapon: nine tailed fox (nine whips on one handle)

Backstory: since both her parents served in the war she was sent to a communal orphanage for the first 150 years of her life. She was then sent away where she bout her house and went to school. Then she accidentally fell into Hell (via portal) and was kept as a slave for 500 years. She was freed by a demon who she fell in love with and they have been secretly meeting each other.
WAIT, I thought she was only 235 years old, how could she be trapped for 500? Also, DemonXAngel is a cliché.

Commentary:All the "Angel" traits are kinda cliché, ya know, but I kinda like the independent feel of her personality. I don't have much to say.

Mary sue level: 42 % Mary sue.
