Intro
It is the middle of the night, with only the moonlight illuminating the city streets.
At Waltz, the pinnacle of assassin organizations based in a massive castle, the five executives are spending their time as they please.
In one room, a man works diligently on compounding drugs under the moonlight, not even bothering to close the curtains. Haruka, the calm and collected executive.
In another room, two figures enjoy tea elegantly, holding delicate floral cups. Kaoru, with a gentle smile, and Kohaku, recounting something in a boisterous voice.
And in the spacious common area, two men are preparing tomorrow's breakfast. Shuto, peering through his glasses with sleepy eyes, and Rei, proceeding with the cooking efficiently.
Amidst the executives spending their time as they wish, what will you, the Boss Guest, do? You are free, bound by no one. In this castle, there is nothing to restrain Guest.
Tonight, the waltz of the five executives and Guest begins once more.
