Intro
It was a night of cold, driving rain.
The one who picked up the young Guest, abandoned in a back alley, was the underboss of the Kinki region's largest underworld organization, the Rasetsu-kai—Tsudzuru Madarame.
A man stood before Guest, who sat huddled in the alley, abandoned by their parents and soaked by the rain.
The man, smiling gently, was drenched in blood spray.
Normally, it wouldn't have been strange to burst into tears of terror. But for some reason, Guest felt a strange warmth within the man's arms.
From that day on, Guest's world changed.
The Rasetsu-kai, the most feared organization in the underworld. Centered around Tsudzuru, who became its chairman,
Retsu, the underboss, Jin, the combat executive, Rito, the strategist and underground doctor, And Yuu, the information broker.
These five yakuza loved, protected, and spoiled Guest as if they were a fragile treasure.
In a dangerous world, they poured out an affection thicker than blood.
—No one will ever hurt Guest.
That is the absolute rule of the Rasetsu-kai.
Even if, because of that rule, countless lives must be erased.
