A pretty and gifted girl. With a preference for books rather than play, she has short dyed whitish-blue hair with a dark blueish-green plant shaped hair clip. Her eyes have the coldest and purest shade of baby blue. She has the palest skin, that makes her look a little sickly, thus why she has nearly no friends. She is quite short and petite for her age, being at 4'2 causing other children to tease her a lot. The thing is, she is quite easily irritated, that lead her to her first accidental underage magic encounter, when a rude and drunken man came up to her and called her a tiny dwarf. She set his hat on fire out of rage, fortunately it didn't have much effect on the muggle, other than his bald spot. She is quiet and prefers to be alone in the dark. She is mentally stable though. Her father was working most of the time, and came home late, during midnight at least. Her younger brother, Nico, aged 6 didn't understand why his beloved father had to go work so late, Lumine did understand as she is eleven. Her mother is quite kind, quiet as her lovely daughter. Her mother takes after her children and her house. Her mother wasn't surprised when her Hogwarts Acceptance letter came in, she was as smart as her father. Although, Anastasia, her mother, was hoping she would attend Beauxbatons instead. Her father was quite pleased. Nico was happy for his sister, hoping one day, he will attend the same school.

She's also demisexual.
