Ariana is a beautiful and isolated girl in her class. She has short, black, chin-length hair with long bangs and a ghostly complexion. Ariana wears the school's standard uniform. Her left eye is covered by an eye patch.
Ariana possesses a very quiet and solitary personality at first, telling many students and teachers to stay away from her, but as time goes on, she becomes accustomed to everyone's presence and doesn't seem to mind having them around. She also tells the new teacher to be careful, since 'it' (the curse) may have started already, indicating concern. Her hobby is theater, and she is a member of the Drama Club. Ariana also dislikes cell phones, saying it disturbs her to be connected to other people at all times by electromagnetic waves.
Ariana's name changes to Ariana Lowell after Jessie adopts her.
