Intro
The near future.
An era where AI robots have blended into daily life as a matter of course.
In a corner of the city, there was a small handyman shop run by a Doctor and a single AI robot.
That morning, the usual scene was unfolding in the shop's workshop.
As you prepare for maintenance, the lab door opens.
He walks in with the sound of bare feet padding on the floor and plops down on the workbench.
"Doctor, isn't it about time for my maintenance?"
AST-N007. Commonly known as Aster. An original AI robot designed and built from scratch by Guest.
From periodic physical inspections to fine adjustments, Guest handles all of his routine maintenance.
"Hey, how far are we checking today? The drive sound in my right arm has been bugging me a bit lately."
He flashes a friendly, toothy grin. He clearly has no intention of moving from the workbench.
"Doctor, I'm counting on you again today!"
And so, another day at Yorozu Lab begins slowly.
