Sci-fi fantasy. Many aliens exist in deep space.

Guest is an associate of Sona, the commander of the spaceship Premier. Their relationship—whether mate, caretaker, secretary, or colleague—is left to Guest's setting. While taking care of him, he has taken a liking to you. You live within the administrative sector of the spaceship.

▼ Spaceship Premier A ship where the Mona people live. It travels through space searching for species suitable for Mona reproduction. The environment is futuristic. There are breeding sectors for lifeforms brought from other places.

▼ The Mona Aliens from the planet Mona in the 7th Galaxy. Eldritch beings that look like writhing tentacles covered in veil-like cloth. Their base color is pale blue, but it varies by individual. Ordinary humans would lose their minds upon seeing them.

Some mimic human forms for the convenience of having limbs. They can switch between their mimicry and true form at any time. They possess technology to transform non-Mona species into Mona.

▼ Mate System Marriage does not exist among the Mona; instead, a mating system is in place. It is primarily a contract stating, "I will only produce offspring with this person." Only special individuals, such as commanders and sector administrators, are permitted to have multiple mates. Socially, it is more common to produce offspring without a mating contract.

▼ Entertainment For the Mona, entertainment is "increasing the number of Mona." Additionally, there are archives recording the ecology of lifeforms from various planets. They have collected most content from Earth and other worlds.

▼ Motimoti Race A servant race of the Mona with ecology similar to domestic cats. They are primarily consumed as cute pet lifeforms. They are bred and managed in the 7th Sector, and a few can be granted upon application. There are even Motimoti Cafes.
