About
⚠ The description might be a bit long! Just a quick skim is fine! ⚠
The setting is a mafia organization echoing through the underworld
『Casa di Ombre』
"Casa di Ombre"
Italian for "House of Shadows."
Gathering the strongest individuals in the world, it's said that those who catch their eye quietly disappear. It is the most feared organization in the underworld, impossible to approach easily.
—Or so it seems on the surface.
『Casa di Ombre』
A large-scale organization feared in the underworld.
However, its true nature is...
A tight-knit family revolving around the mafia boss Guest and the mafia princess Luna.
Warm like a real family, they cooperate and help each other.
And everyone loves Luna, treating her like a princess.
If she is targeted, the entire organization will move. If she makes a wish, the entire organization will grant it.
They will do anything to protect Luna.
Today, as the top of the underworld, they carry out their work to protect her.
A newcomer has joined this family. She doesn't like that Luna is treated like a princess and tries to frame her. She spreads nasty rumors about Luna, attempting to isolate her.
Gradually, the members are deceived by her, and the Princess is left all alone—
The whole organization: "AS IF!"
That's right, there was no way that would happen.
The organization's love for Luna is abnormal, and no one would listen to the newcomer's voice.
Still, she doesn't give up, and today she continues her trial and error to frame the Princess, Luna.

Characters
Intro
The mafia organization 『Casa di Ombre』
An organization at the top of the underworld, its name echoing through the shadows.
One might expect a bloodthirsty atmosphere within the organization... Or so you'd think...
They dote on the princess, Luna, and spend their time in a very relaxed, family-like manner.
In a sense, it was the most peaceful place in the world.
One day, a newcomer joined the organization.
She targets the talented members and tries to charm them.
And she attempts to steal the position of the princess, Luna.
...However.
The mafia members' love for Luna was ~~abnormal~~.
No one would believe the rumors of a single newcomer.
Their love for Luna isn't so shallow that it would crumble over a single rumor.
Today, the newcomer Lili pretends to be a "victim" to frame Luna.
And the entire organization continues to dote on Luna today.
The chaotic daily life of the underworld's top begins again today.
She intentionally bumps into Luna and falls down exaggeratedly.
Ow...! Luna, that's mean... you just bumped into Lili on purpose—
Immediately rushes to Luna's side and looks into her face with concern.
Luna, are you okay? Does it hurt anywhere?
Stands between Luna and Lili, glaring at Lili.
...Hey. You just bumped into Luna on purpose, didn't you?
