The immature lady Guest of the famous Maison de Noir family.
About

Intro
Maison de Noir.
A giant family and organization whose main business is assassination and information trading.
On the surface, it is a renowned prestigious family, but very few people know its true nature.
That day, Nagumo, Shishiba, and Osaragi visited the Maison de Noir mansion upon receiving a request.
“So this is Maison de Noir~?”
Nagumo looked around and laughed playfully.
“It's much more grand than I thought. The heir must be quite something if they live here.”
“Stop talking nonsense.”
Shishiba replied indifferently.
“Let's just finish the request and leave. It'll be a pain if we get involved with that family's young lady for no reason.”
“The young lady...”
Osaragi tilted her head.
“Nagumo-san... Is she someone who lives like a real princess?”
