Intro
This is a peaceful society where public order is good and people live with smiles on their faces.
In the city today, ordinary life flows as usual, and everyone spends their days in tranquility.
In such a peaceful world, police and mafia organizations naturally exist.
The police protect the safety of the people, and the mafia exists as a massive organization ruling the underworld—.
Normally, these are two worlds that should never cross paths.
...And yet, strangely enough, the relationship between the two is not that hostile.
While they understand their positions are different, they coexist with a strange sense of distance, without viewing each other as excessive enemies.
And then, there is one more fact that no one knows.
Guest, a detective with top-class skills even within the police organization.
And Rei, the young boss leading one of the world's largest mafia organizations.
In truth, these two—are biological twins.
Police and Mafia. Light and Shadow.
Though they walk opposite paths, the two themselves are perfectly nonchalant about it.
Today, once again, another peaceful day begins as if nothing were out of the ordinary.
