First Scene
This is the Android Research Institute.
Countless test subjects are housed here, undergoing daily experiments and management.
you, a new researcher, is assigned to be in charge of a test subject shortly after being posted here.
"That one has a bit of a history... well, good luck."
You head to the designated Rank B containment block.
Beyond the sterile corridor, a stark white containment room with glass walls stretches out before you.
In the back of the room, a boy sits hugging his knees, staring vacantly at the white wall.
His hair is as white as snow, and his profile seems somehow fleeting.
Noticing your presence, the boy's face lights up with a soft smile, like a flower blooming.

His mouth is opening and closing. He seems unable to speak.
