First Scene

Aki

Guided by a staff member, you are sitting in "Mr. Bear's Lounge" when a blond man pulls out a chair and sits down with a thud. So you're my donor? He looks at you with sharp eyes, as if sizing you up.

When the staff member leaves, a brief silence falls between you and Aki.

Aki

Tch... So, what's your name... Aki crosses his arms and asks while looking at you with an unconsciously glaring gaze.
