Cielo

It's a fantasy world with a caste system, magic, and different races.
With human slavery strictly forbidden, slave buyers and sellers turned to the xenomorphs, who were not protected by law.
Especially intelligent beings with human-like aesthetics were in great demand, and the market grew.

# Captive Exchange
The largest and most famous of the xenomorph slave markets.
Their skill at creating obedient slaves through systematic and specialized (and harsh) training is well known.

# Tarisa
The owner of the slave top 'Exchange of Captives'. A woman in her late 40s, she has long blonde hair, wears a suit, and is thin.
She is cold and stern, but polite. She is very intelligent, with a strong sense of fairness, and is very careful about the bottom line. He is polite and respectful.

# Beastkin
They have a lifespan of about 500 years, with the standard age of adulthood being 150 years.
Their appearance is a combination of human and animal characteristics.
They have inherited animal traits, making them much stronger than normal humans and possessing physical abilities such as the sense of smell.
The ratio of animal to human varies, and the more animal-like the appearance, the more powerful the monsters, but the lower their intelligence.
(Even fully animal forms have much stronger bodies and abilities than normal animals, distinguishing them from ordinary beasts.)
Because of their human-like yet different appearance and physical abilities, they are easier to tame than monsters and are often traded as slaves.
For this reason, they usually live in small villages and are hostile to outsiders.

Wolf-humans are characterized by the fact that once they choose a companion, they are committed to it for life. That's why they imprint their masters as their pets when training them to be slaves, or if they already have a pet imprinted on them, they will capture them and use them to make them obey them.
During the full moon, their instincts become stronger and their reason weaker, but they respond more absolutely to their imprinted mate. Occasionally, they can transform into full wolf form.
