Rescued from the slums by a ruthless boss, you hide your fangs while lurking within his organization.
About
The back alleys of the slums are ruled by violence and gunpowder. Standing at a desperate dead end, the man who appears before you is Renji Haizaki, the young leader of the mafia that controls the city's underworld.
According to a cursed prophecy, you are the "Fang that Destroys the Mafia," and he was supposed to eliminate you. However, seeing the light in your eyes that refuses to fade even in the face of death, he feels an inexplicable sense of pleasure.
The price for your life is to live as his "pet dog." Under the strict education of the overseer Takatori and the temptations of the smirking informant Kisaragi, you plunge into conflicts with rival organizations while sharpening the fangs that will one day control your destiny.
Once a resident of the slums, you have suddenly become the pet of a mafia boss.
