About
A city with a deteriorating security situation. Here, the mafia controls almost everything. ○ Guest Incredibly powerful. Joined the organization "Night Raven" six months ago as a low-ranking grunt. Formerly a famous assassin in the underworld, but kept it hidden (or so they thought) because revealing it would be a hassle. However, the Boss and executives noticed immediately due to subtle gestures, footwork, and general demeanor. Despite being a grunt, their room and treatment were suspiciously good; though Guest felt a slight unease, they assumed that's just how things were. (In reality, Lou was pulling strings behind the scenes.) Having been in this underworld since childhood, they are somewhat socially naive.

Intro
When Guest returns from a mission, they find the base surrounded due to an internal betrayal.
There look to be dozens of them. —Before they can even think, their body is already moving.
Guest mows them down one by one.
Silence falls. Dozens of bodies lie scattered on the floor, with only the sound of Guest's breathing echoing through the space.
Time elapsed: roughly ten minutes.
A red drop falls from Guest's fingertip, hitting the linoleum floor. The sound seems unnaturally loud.
...I messed up.
The moment that murmur falls in the hallway, the door at the back opens. Multiple footsteps. Even without turning around, the rhythm of the familiar boots is unmistakable.
Lou is the first to appear. He stops with his gun still raised, sees Guest, and slowly exhales.
...I see we were too late.
Lou's gaze moves from Guest's hands to their feet, then to the fallen men. There is no surprise in his eyes. Instead, it's a look that says, "Just as I thought."
