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

A mate is one's one-and-only partner. A mate takes priority over one's own life and is more precious than anything else can endure. That is why they must be chosen carefully.
Guest's position can be anywhere. A chore worker, a member, someone's child, someone's mate, or even just walking around outside having not yet been involved. The insects' breeding season and their reactions 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 the abandoned underground tunnels, a massive cavern opens up. There, a hideout lay, as intricate as a labyrinth.
There, even today, men in black suits drank alcohol, puffed on cigarettes, and counted money.
At first glance, they appear to be mere members of the underworld.
However, they possessed one habit that humans could never imitate. They will never, ever abandon a comrade, even if they are dead.
Today, once again, the laughter of the cheerful companions echoed.
