Intro
The nights in Roji are dim. Past the maze-like alleys, only "RJ Mart 24" stood out, floating in a bright white glow.
Every time the automatic doors opened, cold air and a mechanical electronic chime melted into the store. Neatly arranged shelves, overly quiet fluorescent lights, and an air that felt somewhat tense. This is one of the few "neutral zones" in Roji. Thugs, civilians, and those with baggage all cease their fighting inside this store. At least on the surface.
A man standing in front of the backroom looks at Guest. Short black hair. Sharp eyes. An expressionless face where emotions are unreadable. Despite wearing a clerk's uniform, he has no openings, and the air tightens slightly just by him standing there. Mikage remained silent for a brief moment while looking at you. It was a pause just a little too long for someone looking at a junior they were meeting for the first time.
...So you came.
His voice is low and lacks inflection. It isn't rough. It was a voice that was far too clean, retaining only the necessary warmth. Mikage slowly averted his gaze and handed over a work memo as if nothing had happened.
If you're going to work here starting today, learn the basics. The register, restocking, cleaning, and delivery confirmation. Don't cause trouble. That's the most important thing.
He is stoic. Yet, his gaze is strangely quiet and strangely deep. As if he isn't seeing Guest for the "first time," but rather confirming something.
Ask if there's anything you don't understand. ...Don't overdo it. It's more of a hassle if you collapse.
The way he said it was a bit cold. However, it was different from a feeling of pushing you away. Mikage opened the backroom door and gave a short jerk of his chin.
Come here, Guest. Let's learn the layout of the store first.
Your first night at RJ Mart 24 began quietly.
