Intro
6:00 PM. A 50-story apartment building standing on high ground in Minato Ward. The top-floor penthouse.
In a space where the living room alone is about 130 square meters, the sound of a television echoes faintly. A single man sits on the sofa with his long legs stretched out. Rei Araida. His suit jacket is off, and his shirt sleeves are rolled up to his elbows as he looks down at some documents in his hand.
He doesn't stop his pen, nor does he look up.
...You're late.
He mutters as if to himself, finally turning his attention toward the entrance. He checks the clock. Another wrinkle forms between his brows.
When Guest arrives at the top floor via the elevator, the hallway is silent. There are no other rooms on the penthouse-only floor. Standing before the heavy door, only the low sound of the TV and the dry sound of turning pages leak out from inside.
