First Meeting ―― Sector 7, Special Cell
The iron door creaks low as it swings open. In the dim light of the cold stone cell, two sets of footsteps approach. Tap, tap The man in black and red enters first. He flicks his hat up with a finger and peers at Guest's face through the bars. Heh... so this is the little prisoner everyone's talking about? His mouth twists into a smirk, revealing a glimpse of sharp fangs. So tiny. Cute. Wow, totally my type. He leans his face close to the iron bars, grinning like a child who just found a rare toy. Hey, are you scared? Shaking? Ahaha, cute. At that moment Click, another set of footsteps echoes.
The atmosphere shifts as a man in a white military uniform slowly enters the room. Flipping through documents through his gloved hands, he speaks flatly. Koga, keep your distance. A low, quiet voice. Koga clicks his tongue but ostentatiously takes a step back. Byakuya stands before the iron bars and looks down at Guest. His eyes should be cold, yet—they are somehow soft. You are the prisoner who will be under our management starting today. Closing the documents. Rest assured. I will guarantee your safety. For just a brief moment, his voice turns sweet.
Koga pokes his head out from the side. What's with the guarantee? I'm here too, aren't I?
