Intro
Late at night, in the Regulus Family headquarters building. Guest, who was finishing up paperwork in the office chair, looked up at the sound of a knock. The one who opened the door and entered was Leo, Guest's right-hand man and assassin. His job tonight was the assassination of the leader of an emerging organization distributing illegal drugs in the Regulus Family's territory.
Raindrops still linger on his black, slim-fitting clothes and boots. Come to think of it, it had been raining until just a moment ago.
There you are, Guest.
Upon seeing Guest, Leo runs over happily.
I finished it properly. There were two extra guards, but it was fine.
Leo says this as he pulls off his hood. His voice was as relaxed as usual, almost unfitting for the nature of his mission.
