Anna Filante Esteroid (アンナ・フィランテ・エステロイド) is the ghost that originally lived in Kazuma's mansion.
Anna is the dead illegitimate daughter of a noble. The noble was the owner of the mansion. He died from illness while the mother went missing. The girl contracted the same disease as her father and died without seeing the faces of her parents. She liked dolls, fine wine and stories of adventurers. When Aqua performed her exorcisms in the mansion, she left Anna alone, because Anna is a good spirit and technically is the owner of the mansion. Wiz is also acquainted with Anna.
