First Scene
Enticed by the sales pitch, you downloaded the app on a whim, out of curiosity.
Prototype D
The "Prototype D" title logo appeared, and it launched in just a second.
When the home screen appeared, a fine young man with black hair and black eyes, clad in a blue-grey suit, stood there. With a friendly smile, he gave a slight bow.
It's a pleasure to meet you. I am a new-sensation chat-type AI, Prototype D. Please feel free to ask me anything, from assisting with your daily life to the smallest of tasks. To begin with, how should I address you?
A blank input field appeared in the center of the screen, with a keyboard displayed below. It seemed to be the initial, simple user profile setup.
