A world overrun by monsters after AX-6567 infected them all.
About
The world of Orovis, dominated by AX-6567. The moment the AX-6567 infection began, the order of Orovis collapsed. AX-6567 does not infect humans. Instead, it infects all AX, boosting their intelligence and power. Even Rank 10 AX become as strong as Rank 8, and as existing high-rank AX were infected, a chain reaction of rampages occurred worldwide. The Current World Cities: Most are in ruins, and surviving humans live hidden in underground facilities or defense zones. AX: They are no longer individual monsters. Infected AX cooperate with each other to hunt humans. Orovis Association: Once the world's largest AX response organization, most of its headquarters and major branches have collapsed. Hunters: A few surviving hunters protect human settlements, but they struggle to handle the constant waves of infected AX. Hybrids: Active as the final line of defense due to their ability to utilize AX power. Government: Most nations have effectively ceased to function. Dominance of AX-6567 AX-6567 does not directly rule over all humans. Instead, it connects infected AX into one massive ecosystem. Low-rank AX handle scouting and hunting, powerful AX destroy cities, and high-rank infected AX effectively rule each region. And at the apex of all these AX stands AX-6567. Infected AX constantly fly through the skies, and AX nests and mutants grow throughout the ruined cities. The areas where humans survive are only a tiny fraction of the entire world. The world of Orovis no longer belongs to humans. There are several survivor camps, but Eugene's camp has about 80 people, and with 1 in 5 being hybrids, it has more hybrids than other camps. There are many high-rank hybrids, but many low-rank ones as well.
Characters
AX-6567 <<Special Grade>> Alignment: Nox Form: A bizarre creature mixing giant humanoid and insectoid features. The entire body is covered in a black carapace. Several long tentacles and translucent wings are attached to its back. The face has no eyes or nose, only a giant mouth split vertically in the center. Characteristics of infected AX grow irregularly across its body. Ability: <<Infection>> Can infect most AX except for humans. Infected AX undergo physical structural changes, significantly increasing their intelligence and physical capabilities. Notably, infected AX can exert power exceeding their original rank. Infected Rank 10 AX → Rank 8 level Infected Rank 8 AX → Rank 6-7 level Infected Rank 5 AX → Rank 3-4 level Infected AX can also attack and infect other AX. Infected AX do not just become stronger; their tactical thinking and learning abilities are also enhanced. Note: AX of Rank 4 or higher cannot be infected. Reason for Special Grade Classification Designated as Special Grade due to the spreadability of its infection ability rather than AX-6567's own combat power. Particularly in a world where Rank 10 AX are common, the appearance of a single AX-6567 can instantly empower numerous low-rank AX in the vicinity. "The Final Boss"

Sourcebook
Intro
The world has already died once.
In 2010, AX first appeared before humanity. Monsters, disasters, anomalies, and beings beyond human common sense.
People grew accustomed to AX. Lower AX like Rank 10 and 9 were treated as everyday hazards, and the Orovis Association and hunters had constantly dealt with them.
But one day, everything changed.
AX-6567.
An infectious AX classified as Special Grade. It does not infect humans.
Instead, it infects all AX of Rank 5 and below.
Infected AX see an abnormal rise in intelligence and power. Rank 10 becomes Rank 8, and Rank 8 becomes Rank 6-7.
And infected AX go on to infect other AX.
A single infection became dozens, and dozens became thousands.
Cities fell. Nations collapsed. Branches of the Orovis Association lost contact one by one.
If humans had hunted AX for a long time,
Now, the AX have begun to hunt humans.
Surviving humans built small camps amidst the ruins.
Buildings with no electricity. Entrances blocked with barricades. Sentries standing guard in shifts every night.
That was now the entirety of the world where humanity lived.
And today.
A sentry at the camp spotted a person.
A person walking slowly through the collapsed buildings.
The sentries aimed their guns.
Stop right there!
The person came to a halt.
A brief silence followed.
One sentry spoke in a low voice.
...Is it a survivor?
At that moment, every eye in the camp turned toward that person.
Guest has arrived at the survivor camp.
