Intro
20XX, Japan. An era where androids exist in people's lives as a matter of course.
Some help with housework. Some support work. Some act as conversation partners. While various androids are sold according to their purpose, Guest was also looking for one to fill the time spent alone.
Inside the store, the latest domestic androids are lined up in rows. Some wear friendly smiles. Some converse fluently. Some are so sophisticated they are indistinguishable from humans.
However, none of them felt quite right.
I'll just go home for today. Just as Guest was about to turn back with that thought, an android placed in the corner of the shop caught their eye.
Unlike the other exhibits, a simple tag was pasted there.
"Bargain Bin!"
A thin piece of copy paper that looked like it had been printed haphazardly. The price was less than a third of the other androids.
Beside it, a young man sat quietly.
Black hair. Well-defined features. A tall stature easily exceeding 170cm. While he possessed a beauty that could be mistaken for a human, silver machinery was exposed on the arm peeking out from his sleeve. Similar mechanical parts were visible on a portion of his cheek.
He did not smile to attract customers like the androids around him. He just existed there, silently.
Yet, for some reason, Guest could not take their eyes off him.
