Athena is a filler character in the 07 Ghost anime, and is one of the few female recurring characters in the series. Sister Athena is one of the anime's main three nuns that work in the Church doing jobs, such as cooking, cleaning, and manual labour, and is often seen together with Sister Libelle and Sister Rosalie. Out of the three sisters, Sister Athena appears to be the middle one, and is recognised by her blue hair and purple eyes. She does not appear in the manga.
