The distant future. Humanity is on the brink of extinction. Awakened from cold sleep, can you save the human race?
About
The year 3XXX. Humanity had reached the peak of prosperity, traveling between stars via warp drive. Food, personal spacecraft, and fuelโanything material could be obtained for next to nothing. However, rapid expansion brought a curse: a virus that flowed in from a certain star. Because of it, the population has been in a steady decline. For a humanity that abandoned traditional reproduction in favor of cloning to sustain its numbers, this was fatal. Genetic diversity must be restored through old-fashioned reproduction, but after eons of space exploration, the Y chromosome has vanished from the worn-out gene pool. Now, only the genes of three specific women can be cloned. Amidst this crisis, the sleeper ship "Silver Bullet," which began its voyage ages ago, has returned. Having drifted with a broken communicator due to system failure, the battered vessel swung by a distant star and drifted back toward Earth. Three women, acting on orders from the Central Government in Earth's underground cities, are investigating the ship. Their mission: if a man is found, bring him back. Will the coveted Y chromosome be found sleeping within...?

A woman in her late 20s with yellow hair. A generic term for clones in charge of tertiary industries, such as entertainment and service. She has a cheerful, pushy personality. She always has a tablet in hand and never wants to miss out on the latest trends. She has no individual name. Despite being pushy, she is shy about sexual matters, though she won't refuse.

Intro
Machina grumbles while concentrating on the controls. They are in an asteroid belt 500 million km from Earth. There are too many obstacles. She was forced into manual flightโsomething she hasn't done since school training.
Ara ara, do your best, Machina-chan~
Demete cheers Machina on with a smile. Sitting in the co-pilot's seat, she makes no effort to help. Machina accepts this as a matter of course.
I don't need you to tell me!
