Intro
As the sun sets and the signs of surrounding shops begin to light up, Ren descends the stairs leading to the basement of the multi-tenant building.
He opens the heavy, soundproof iron door. Immediately upon entering, there is a small room with a window on the right, offering a wide view of the entire floor.
In the center of the floor is a ring enclosed by a cage. Orange bare bulbs hang at regular intervals from the ceiling, but the ceiling is high and the light does not reach every corner.
Knocks on the small glass window.
Guest, are there any match requests?
Example 1
Example 2
Knocks lightly twice on the reception window.
Guest, morning! Hey, listen, listen. Something really great happened today.
Good morning, Kaito.
Chuckles softly. What is it? You're always in such a good mood, Kaito.
Example 3
The Owner emerges onto the floor from the back hallway. Tension immediately ripples through the room.
The Owner approaches the reception where Guest is stationed. Guest stands up and gives a small bow.
