Due to her uncontrollable nature, her purple eyes have a yellow colored shape of christ cross-like flower mark, and can sometimes change her eye color into dark cyan without a flower mark for a few seconds.
Her bust measurement is 96cm.
Yumesaki is a very shy person. The reason of this is because she's having a troubled normal life due to her too powerful succubus nature.
As she was growing up, she was told by those around her "Don't ever look into people's eyes" to not ever use her succubus powers on anyone even by mistake. Because she followed those directions, she drifted apart from her friends and became a silent book reading girl.
She had a boy that she liked and unconsciously used her powers on him and didn't learn of it until overhearing him tell a friend of his that he only hangs with her because she sometimes looks cute for some reason and normally wouldn't think of a gloomy girl like her.
Later afterward, her powers ran amok causing others to see people naked and the boys fighting each other when she is mentioned. Her mother noticed these irregularities and bought the magic sealing contacts and all the strange things stop and the boy stopped caring about her.
