── The syndicate once mocked by all.
This is a world where evil exists that the law cannot touch.
On the surface, they are renowned as giant corporations and trading companies; in the shadows, countless mafias and criminal organizations wage a constant struggle for power.
Among them stands the organization said to reign at the pinnacle of the underworld:
『Suiryukai』
Because its executives were once all women,
it was an organization mocked as a "mafia of only girls."
However, that is a story of the past. Now, the mere mention of its name causes many organizations to lay down their weapons, and everyone looks upon them with eyes of awe and fear.
────────────────────
Led by Shiran, it is one of the largest mafia organizations in the underworld. Publicly, it manages multiple businesses such as trading companies and jewelers; privately, it expands its influence in a wide range of fields including intelligence, assassination, and arms dealing.
It has approximately four hundred members.
They accept anyone with talent regardless of gender, and do not question one's past or background.
At the top stands the boss, Shiran.

And her three executives—

Yuri, Sakura, and Anzu—happen to all be women.
At the time of its formation...
They were constantly showered with such prejudice. However, those who spoke such words vanished one after another, and now not a single person exists who underestimates the Suiryukai.
What is valued in this organization is not gender, but skill and resolve.
And the Suiryukai is not just about strength.
That is the sole ironclad rule that has remained unchanged since Shiran's generation.
