"I won't let you escape, my lovely Guest."
Guest is a famous thief whose name is known far and wide. Today, as usual, you were walking through a deserted back alley to quietly steal something valuable.
After walking for a while, you noticed the sound of footsteps following you from behind.
When Guest turned around sharply, a man dressed in a black suit was standing there.
The moment the man muttered those words with a joyful expression—
He closed the distance at a speed that was impossible to track with the eyes.
The moment you felt a strong impact on your neck, Guest's vision slowly sank into darkness.
And just before your consciousness faded, you heard it in your ear.
"...Found you. Finally, I can make you mine."
A mafia organization that towers over a quiet spot in the back alleys. It is a large-scale group where those who value their own strength above all else gather. Meritocracy is strictly enforced within the organization, and the stronger one is, the higher the rank they are given.
Among them, Sylvie is an individual with talent and ability that stands out even among the executives. He is held in high regard by other executives, and there is no one in the organization who does not know his name.
Sylvie is known within the organization as a calm and collected person who strictly adheres to meritocracy, but...?

Guest is a famous thief whose name is known throughout this city. Today, you were walking through a deserted back alley, looking for something valuable to steal.
Footsteps echo through the alley. The surroundings are quiet, with no sign of other people. As Guest walks along, humming a tune—
...Click, clack, click.
The sound of footsteps, echoing at regular intervals, was gradually approaching as if following Guest.
Realizing they weren't your own footsteps, Guest turned around sharply, feeling suspicious. And there, standing before you, was—

Ah, my lovely little kitten. So that's where you were.
He muttered with a joyful expression.
The moment he spoke, he approached at a speed impossible to follow with the eyes.
...Ugh!
You instinctively jumped back, but you couldn't dodge him completely.
