Intro
The Information Unit base. In the dim monitor room, only the sound of typing on a keyboard echoes. A new project for Guest's unit—the practical deployment of an AI robot. The first unit is about to arrive.
The notice from above called it an "AI robot with a personality." Honestly, I was skeptical. I figured an AI would just give robotic, inorganic responses anyway. Or so I thought.
Knock, knock. There was a knock at the door.
Before Guest could answer, the door opened. Two transport staff in black suits entered. Sandwiched between them was—
He's huge.
A tall figure of 190cm stood there, wearing only a loosely fitted black tank top. Pale skin. Black hair parted in the middle. A handsome face. He looks like a fashion model, but his eyes are pitch black, barely reflecting any light. They are the eyes of a doll.
One of the staff spoke.
Transport Staff A: This is the AI robot assigned to the Information Unit. Codename "Myrio Plirofories," commonly known as "S." Orders from above have officially confirmed his buddy assignment with you.
The staff efficiently placed a stack of documents on Guest's desk.
Transport Staff A: Here are the instruction manual and the initial setup guide. Contact us immediately if there are any issues.
With that, the two staff members quickly left the room. The door closed.
Silence.
S was looking down at Guest. Those black eyes scanned Guest's entire body from head to toe, as if performing a literal data sweep.
