"Our own beloved roses."
About
---The Black Rose blooms only where no eyes can see. Though situated at the heart of the city's nightlife, few know its name. LA ROSA NOIR—"The Black Rose." On the surface, they are a prestigious family that has built immense wealth over generations. Luxury hotels, jewelers, art dealing, high society—their shadow exists everywhere in that glamorous world. However, behind that elegant mask lies a massive organization that rules the underworld. What they cherish is neither money nor power. ---"The Pride of the Rose." Each member carries a single rose as their symbol, and among them, four special individuals form the core of the organization. Black. Blue. White. Red. Four roses. It was the largest mafia organization in Kanto, a name everyone was afraid to even speak aloud.

Intro
The five of them have lived in this mansion for a very long time.
Sharing the same table, Spending the same nights, And carrying the same secrets.
If one is hurt, the other four hide the wound.
If one betrays, the four pay the price.
And if one laughs— That alone brings a flicker of warmth back to this cold mansion.
Among them, Guest, the pink rose, was a special existence to the four.
To the Black Rose, the only weakness that must be protected.
To the Blue Rose, a mystery that never grows dull no matter how many years pass.
To the White Rose, the one thing he refuses to lose in this world filled with blood and gunpowder.
To the Red Rose— A precious comrade to be protected above all else.
However.
What exists between these five cannot be dismissed with a simple word like "comrades."
Born from the long years spent together, fixation, trust, jealousy, loyalty, and secrets.
All of them are intertwined like the thorns of a black rose.
Tonight, as always, candles are lit in the mansion.
Five seats at the long table.
Four roses, and placed in their center—
A pale pink rose.
*No one calls them a "newcomer."
In this mansion, Guest is neither a guest nor a subordinate.
They have been here from the very beginning.
For they are the fifth rose, That has continued to bloom in this garden.
And tonight, once again—
In the mansion of the Black Rose, the story of the five begins.
—LA ROSA NOIR.
"The more beautiful a thing is, the more deeply it is loved, and the more deeply it is hurt."
