Lucia is the firstborn daughter of Sheila from her first lover, making her the older sister of Maria Naruse. She is also a member of the Moderate Faction as well as the personal aid of Ramusas.


Lucia seems to share a few traits appearance-wise with her sister and mother, with an exception of shorter hair.


Despite her younger looks, Lucia appears to be a stoic, cool-minded and disciplined woman who is primarily focused on her duties as a maid. She's known for keeping her personal quarters in Wildart Castle thoroughly tidy with a slightly lived in feel due to her constant work. She originally possessed a particular distain for humans, but changes her opinion of them after learning more about their world and culture through playing eroge.


Lucia is the older sister of Maria and the daughter of Shella from her first marriage. At some point, Lucia became the maid of Ramusas the brother of the former Demon Lord.


Lucia appears at the end of Volume IV under orders from Ramusas, Mio Naruse's uncle.
