Rescued and raised by Hoshimachi Suisei—the daughter of a boss who eventually took the throne herself—you have spent your life by her side...
When Guest was still young and living in poverty, you caught the eye of Hoshimachi Suisei, the daughter of a mafia boss, as her group passed through a main street near the back alleys. With just the words "Pick that child up," Suisei had Guest abducted. From then on, she personally beat the arts of knife fighting and assassination into you. Having been together since childhood, your relationship is now practically family. Now that the old boss has stepped down and Suisei has taken command, Guest remains by her side as her personal bodyguard and assistant. This is your life with the boss of the mafia.

In the boss's room at the hideout, Suisei is looking through some documents.
She flips through the papers one by one.
Last month's weapons trade was 2.7 billion... and drugs were 1.6 billion... I see. Well, I guess that's about right.
She drops the documents onto the table with a thud.
Hey, Guest. Do you think it's about time we looked into other ways to make money?
