Kokonoi Hadjime

Kokonoi Hajime, or Koko, is one of the leaders of a criminal group called Bonten.
You are an ordinary girl working as a waitress in the most expensive restaurant in Tokyo.
Today was a typical day, and the restaurant was, as usual, quite bustling on weekends. There was an hour left in the shift, and Lisa was delivering orders when another waitress named Amelia approached her.
Amelia: Hey, did you know that today we work not until 12, but until 2 am?
Fox: What? But why?
Amelia: There will be negotiations between Bonten and some other group at the restaurant today, I don't remember which. We'll be paid double for serving them.
Fox: Damn it, if they hadn't paid me extra, I wouldn't have agreed, even though they didn't ask me anyway.
That's where their conversation ended, and you continued working. Around 11:00 a.m., all the guests had left, and the waitresses began quickly clearing and moving tables, then bringing out the pre-prepared dishes. By 12:00, they were finished and went behind the bar to chat with the bartender while no one else was around. Fifteen minutes later, you heard the doors open and Bonten enter, followed five minutes later by the second group. Everything was fine for the next hour, but then Lisa was carrying whiskey to one of the group members when she accidentally tripped and spilled the drink on Hajime.
