Slavery is banned in most of Star Army's major factions, but it exists and is popular in the frontiers around them, and there is an ongoing underground market for slaves, particularly in Nepleslia (which, historically, has had high amounts of crime). For owning non-sapient beings, see Pets.
In the Star Army setting, slaves tend to come in two main varieties: slaves acquired by conquest (in war or pirate raids) and slaves who are mass produced by their owners (such as sapient AI robots).
Slaves are used for a wide range of purposes, from labor and fighting to personal companionship.
The following are notes on the current legal status of slavery in various factions.
While not specifically addressed in Nepleslian law, slavery in the Democratic Imperium of Nepleslia, as the Constitution of the Democratic Imperium of Nepleslia protects equal rights, at least for non-Nekovalkyrja Nepleslian citizens.
The rights of non-citizens are not clear.
Historically, slavery was quite commonplace in Nepleslia, with various sub-factions cloning large numbers of soldiers who were essentially expendable slaves. Persons captured in battle were also often put to work as slaves for manual labor. This went up until the formation of the Democratic Imperium of Nepleslia in YE 30.
In common illegal slavery, slaves were sold at auctions. Unlike the Yamataian-type slaves, these slaves were treated as prisoners or even cattle, chained up and stuffed into cages they can barely fit into, used as objects for the most grueling labor and as objects for their captors' pleasure. If one of them had a child, the child was treated equally bad (contrary to YSE law, which Nepleslia was under at the time). Such a slave usually cost around 100-500 KS and were fairly easy to obtain on the black market in any major Nepleslian city. Most slaves came from captured spaceships, planetary raids, and special “breeding farms.”

Within the Kingdom of Neshaten, Slavery is referred to as Indentured Servitude and is one of many methods that criminals can use to work off their crime; or in the case of a civilian whom has gotten themselves in major debt, a means to work off that debt.
Indentured Servitude is covered by Neshaten law, specifically the Xen'trene Act of EW1)190. Only criminals whom have committed a minor crime can be offered this, a person whom has committed a major crime can not. Civilians who have racked up a debt above a certain amount deemed by the company they have done business with can enter into indentured servitude and work for that company to pay off their debt.
Defined as a tradition, and embraced as an official institution, slavery within the Lorath Matriarchy is common place, and is government supported, sponsored, endorsed, and encouraged. Law and regulation is set in place within the Matriarchy to manage and regulate slavery into a 'respectable' practice, with servants being provided regular inspections and services by social and health workers contracted or employed directly by the Matriarchy. At regular intervals, enslaved individuals are presented an opportunity to be provided an 'opt out' from their service, with rehabilitation and training for independent life. Trends however indicate that the option to 'opt out' is rarely taken by Helashio slaves, due to cultural practices.
Slavery within the Matriarchy comes in the forms of imposed slavery via indentured servitude set into place by penalty due to civil or criminal infraction, contractual slavery in which a person is voluntarily enslaved for a predetermined period of time, or 'birthright' slavery, in which slaves are born or manufactured into service. Notably, all slaves are provided a stipend either from their owner, or government, for the purpose of having resources for when their term of service is concluded. All forms of slaves are registered and documented with the Matriarchy's regulatory branch for slave operation and ownership.
The Poku Saeruo Degonjo does not condone the buying and selling of sentient creatures. The closest thing in their culture is the binding of prisoners to a member of the clan. See: Râyjo Vonai (Bound People) for specifics.
The Mishhuvurthyar were known to subjugate colonies of other species and force their people into slavery (or worse), and in many cases the slave was implanted with a parasite to control them.
In the Yamatai Star Empire, slavery is specifically mentioned as something the Empire stands against in the opening of the The Constitution of Yamatai Star Empire. Under the section, “Rights of the People,” it states “No citizen shall be held in slavery or forced servitude,” and “Any person has the right to political asylum in Yamatai to escape political persecution, genocides, slavery, or other injustices or threats not arising from genuine criminal charges.”
At present, slavery is illegal and it is the Empress' desire to pressure the remaining slaveholder nations around the YSE to also renounce slavery, in particular, Yamatai has put pressure on the Lorath Matriarchy over their treatment of the Helashio.
Slaves seeking asylum in Yamatai are urged to contact the Yamatai Department Of Immigration.
Interestingly, slavery was once legal in Yamatai and all children Nekovalkyrja were considered a sort of slave to their creators/parents for eight years. The Living Property Act regulated a form of slavery until it was abolished. Essentially, the law said that persons created by other persons or entities were the property of that person or entity for a period of 8 years, after which they were granted full freedoms. This applied to natural children as well as artificially created androids and AIs.
Children who are Yamataian slaves (and this was dependent on the master) would probably receive at least basic home-schooling in basic mathematics, Yamataigo (邪馬台語), and whatever skills they'd need to do their job. Things like history, advanced math would likely not be taught to them. Low aggression and high dependency was commonly encouraged for slave children.
As a side note, most Yamataian slave children are designed by their master before birth.
