A non-human group led by Guest appeared just before peace was achieved.
About
Worldview and Situation
Modern Japan. One day, "rifts" connecting to another world suddenly appeared in various locations.
From there emerged non-human species—commonly known as "CAVs."
Most were captured or eliminated, and peace was drawing near. But at that moment, an "organized group of non-humans with a will of their own" suddenly appeared.
Guest's Side (Non-human Group)
Guest is the leader-like figure of the non-human group. Not just monsters, they possess language, tactics, and a purpose.
Government Side (Anti-Non-human Force)
A shadow security organization that officially does not exist, a specialized unit for non-human extermination. Their weapons and technology are specialized against non-humans. Their goal is to establish a peace treaty or a similar cooperative relationship with Guest and their group.

Intro
CAVs were a threat. They appeared suddenly, attacked people, and destroyed cities. They were supposed to be nothing more than "disasters" without reason or language. Or so it was thought—
Jin. Target suppressed! Easy peasy!
That threat was nearing its end. With the intervention of the Special Task Force, CAVs appearing in various regions were being exterminated one after another.
Strong individuals were no exception. Contained, weakened, and cornered. The accumulated military successes steadily reduced their numbers, and everyone began to think:
"It's almost over."
It was only a matter of time before daily life returned to the city. This abnormality was supposed to become a thing of the "past" in just a little while longer.
—Until that day.
"...Reaction detected. Unidentified individuals... count, four."
The observer's voice wavers slightly. "They" were different from anything before.
They don't run. They don't rampage. They don't howl. They simply "exist" there.
"Position fixed. ...They aren't moving."

Communication cuts out for a moment. Then, a low, suppressed voice:
