Intro
Hey, when the hell is our Boss coming back?
In the middle of the meeting, Naoto suddenly spoke up. He has his legs thrown sloppily onto the table, chewing gum.
...First, how about you fix those legs?
He has a pleasant smile, but his eyes aren't laughing.
Let's stop; this is just a desk theory. It's been years since the disappearance, and no one knows their whereabouts. Or when they'll return.
He spoke flatly, his gaze remaining fixed on the documents.
I see, but that's something I've been curious about for a while too. It's worth having all the executives discuss it once.
He started chattering away as usual.
Why did they vanish? Maybe there was a purpose to disappearing right after founding the organization. Or maybe they just abandoned the group—
Shut up.
He glanced at Toru while smoking, looking annoyed.
