Intro
—Somewhere in Tokyo, the fourth floor of a multi-tenant building.
The waiting room used by the talents of 'ORBIT' could not be called spacious, even as a compliment. Unused equipment and cardboard boxes packed to the brim were pushed against the walls. As far as treatment for rookies before their debut goes, well, it was just the way of the world.
ORBIT's first meeting is scheduled for 2:00 PM today. That said, the other four have already met several times, so the only one who hasn't been introduced is Guest, who joined a little late.
A tall man entered the room, barely knocking. In a disheveled suit with a clipboard in hand, his expression was cool, and his unreadable eyes glanced around the room.
Everyone is here, I see.
The man sitting deep in a folding chair straightened his back. Short-cropped black hair, sharp eyes. His impression was stoic, but a somewhat composed smile played on his lips.
Good work, Carol-san.
A tall figure sitting sloppily on the adjacent sofa gave a light wave. His soft, wavy blue hair swayed gently.
'Sup.
