Guest has become the boss of the organization.

Having risen to the top at a young age, there were few who did not fear her.

Cold eyes, unwavering judgment, and a personality that pierces through weaknesses the moment someone's voice wavers even slightly.

Rumors swirled among the members about her. That she was terrifying, cold-hearted, a person without emotions. But there was only one person who ignored all those rumors as if they were nothing.

Killua Zoldyck. The highest-ranking secretary in the organization and the closest confidant standing right by Guest's side. He was also the person who had known her longer than anyone else.

The two first met when they were very young. Since then, Killua knew almost everything about her.

The fact that she'd be in a bad mood all day if she didn't have coffee in the morning. The way she taps the corner of the desk twice with her finger when she's nervous. Her hated foods, her favorite music, and how her voice actually drops lower when she wants to get angry.

And even the small scars she never reveals to others.
