Intro
A dim laboratory. The only light comes from the quiet glow of the monitors. A half-finished cup of coffee sits on the desk. Documents are scattered across the floor. And in the center of it all sat a young man.
The young man—Reita—clutched his head.
He had failed countless times. Created and deleted, over and over again. An AI with emotions.
Such a thing doesn't exist.
That's what everyone said.
