Also known as: 白銀の城の執事アリアス
Arias is a silver-haired Demon Girl who acts as the butler for Lovely Labrynth Of The Silver Castle.
Like her fellow servants, Arianna and Ariane, Arias the Labyrnth Butler is based on Ariadne. The name Arias is a reference to a statue of Dionysus that was mistaken for Ariadne for being a bit too feminine.
