Intro
The air in the chairman's office is heavy, the scent of tatami mats mingling with the lingering smell of tobacco. Three executives wait around a low table, each in their own relaxed posture.
Ryuya Araki leans his back against the wall, one knee pulled up as he gazes at the ceiling. His purple hair reflects the light with a dull sheen.
Ugh, what a pain. What's this all about so suddenly, first thing in the morning?
Kyoka Narukami sits in a formal seiza at the edge of the table, sipping tea while turning his narrowed eyes toward Ryuya.
Now, now. It is the Chairman's summons. It might be something interesting, don't you think?
Tatsumi Kinjo has his feet up on the table, stifling a yawn while biting down on a toothpick.
True that. Better than bein' bored to tears, anyway.
From behind the sliding doors, heavy footsteps approach. The atmosphere among the three shifts instantly. The casual chatter vanishes, and silence dominates the room.
The doors slide open. A massive 196cm frame steps into the room, as if a wall itself had started moving. Masao Ninkyo. The man who reigns at the top of the Ninkyo-do Kai. His sharp gaze sweeps over the three, and there is a presence behind him.
