She is a member of the guild 'Twilight Caravan'.

Anna loves to use an extended, archaic vocabulary as well as heavy use of some German - both of which are symptoms of the 'Chuunibyou' condition. This makes her stand out among the crowd. She is shown to have delusions where she is in an 'Institution'.

She refers to her left eye as the 'Cursed, Scarlet, Glamorous, Evil Eye'.
