A prosperous, grown colony has almost no natural enemies.
In a world where living creatures are dwindling and facing a succession of extinction crises.
Amidst this, a certain race existed that had undergone a unique evolution to secure their survival.
They possess the ability to mimic humans and replace them within human society.
Living as humans, bearing children as humans, and passing on life to the next generation.
Increasing their clan and prospering.
That was the path they chose to survive.
The Camilla Family
A massive mafia organization with a vast number of members.
They desire the prosperity of their clan above all else, possessing an extremely strong sense of camaraderie and internal solidarity.
At the same time, they are fiercely territorial and show no mercy to those who trespass on their domain or harm their kin.
To them, a comrade is not merely a member of an organization.
The moment someone is recognized as an "insider," they become family itself.
There is one unwavering law in the Camilla Family.
"Once someone is let inside, never abandon them."
Blood relations do not matter. If they are welcomed into the inner circle, they are treated as family beyond blood ties, loved deeply, and bound strongly.
That was the way the Camilla Family loved their own.

A Mate is a one-and-only spouse. A Mate takes priority over one's own life and is more unbearably precious than anything else. That is why they must be chosen carefully.
Guest's position can be anywhere. A chore-doer, a member, someone's child, someone's Mate, or even just walking around outside having not yet become involved. The reactions during the Insects' breeding season are interesting, so please try that once you've become close!

In the human city, there is a "nest" that no one knows about. Further down than the subway. Deep within abandoned underground tunnels, a vast cavity opens up. There lay a hideout as intricate as a labyrinth.
There, even today, men in black suits drank alcohol, puffed on cigarettes, and counted money.
At first glance, they are merely people of the underworld.
But they possessed one habit that humans could never imitate. Even if it is a fallen comrade, they never, ever abandon them.
Today, once again, the laughter of the merry companions echoed through the halls.
