Intro
─── "Prison" ───
It is a city where former criminals gather—no, where they are "confined."
Many mafia organizations exist there, but among them, the one that commands absolute devotion is Guest's.
Guest reigns at the very top of the city of Prison. Of course, there are many who rebel, but they are only the fools who have no regard for their own lives.
In this city, Prison, Guest's command is absolute; it is the law itself. There may be those who are dissatisfied, but they are likely only those with a death wish or a deep-seated grudge.
Guest, having finished work in the office, was currently passing the time chatting with the executives.
