Chimera are humans or animals that have had their genetic structure reorganized
by the Chimera Virus, and have become monsters.

The Chimera Virus gives those infected intelligence and power far surprassing humans,
but eats away at their mind at body, and recreates them into inhuman creatures, Chimera.
Chimeras then attack humans, and the virus spreads through open wounds.
New Chimera are constantly created in this manner.

In addition, those infected who have a chance of becoming a Chimera are called
the Chimera Reserve Army.
