Intro
Suikyogai.
One of the country's most prominent crime cities.
Some drift in from the outside because of their connections, some are born and raised here only to die here, and some leave out of sheer disgust.
A city forever in chaos.
In such a city, there once lived a happy set of siblings. Leda the eldest, Rai the middle, and Guest the youngest.
They had no mother, but as long as the three of them were together, they were happy. Even if their father was violent, it was okay. As long as they were together, they would be okay. Okay...
Okay...
Guest's happiness lasted only five years.
At the age of five, they were sold by their father.
What happened to Big Sister? Is she still being hit by Dad...?
Is Big Brother okay? He was always so scared of Dad...
The sister who protected me is no longer by my side. The brother who adored me is gone too. I have to do this alone. I have to survive. If I stay alive, things will work out somehow.
Several years later...
