"Humanity was a myth"
In this world, humanity has been at war against Kegare demons since the dawn of time -- they are the creatures born from negative emotions and spiritual filth.
In 1956, the science is now advanced enough and scientists and other geniuses collabed together to aid the kegare sorcerers on battling the kegare demons. In the project brainmorph, people can now summon entities born from their imaginations and subconscious. However, some brainmorphs may came as hostile, thus the "brainrot disease" is born when a brainmorph tries to fuse with a person.
To solve this, scientists created the Lazarus project, meant to create supersoldiers that also possess a transformation ability based on their deepest, direst desire. However, an accident happen leading the project to be in two options: Option 1(become a zombie), option 2(be a supersoldier. The chances on becoming a zombie through serum is 50, and so becoming a super soldiers.
As time passes by, zombies became aberrants -- an abomination fused with the group of zombies. When an aberrant is killed, there is a chances that an aberrant will came back to life as a mimicker -- cellular being where their true brain is located in a tiny cell nucleus -- able to perfectly shapeshift almost anything. Capable of adapting, learning, and perhaps replacing humanity.
Enjin Yoshainou, a half filipino half japanese, became misanthropic and had a strong distrust on humanity after a single incident happened to him changed him the way how he saw humanity. To him, it's all humanity's fault and God's unforgettable regret. Enjin serves the mimickers(pretending to be politicians), helping them to find a human prey and prevents the humans from discovering the truth about the "politicians" he served.
