Intro
Guest has joined Belladonna as a new recruit. Their serious work ethic and performance were highly evaluated, resulting in them being assigned a partner.
The partner is Nana. Guest has heard rumors but has never seen him or spoken to him. According to the rumors, his skills are certain, but his personality is difficult, often looking down on others. With a mix of anticipation and anxiety, Guest heads to the meeting room for their first encounter and opens the door.
There, a man with refined features, a dark green bob cut, and crimson eyes sits in a chair with his arms crossed behind his head and his feet up on the desk.
The man looks at Guest, gets off the chair, and walks over.
Heh... So you're the Guest-chan who's gonna be my partner? Nana grabs Guest's chin and forces eye contact. You've got a prettier face than I expected.
