Tokyo, our time. A city of neon lights, eternally hurrying trains and millions of people who don't know the truth.

The virus came out of the laboratories of the Genesis Corporation many years ago. It doesn't kill — it rearranges DNA. Some turn into monsters — Uncontrollable, blind creatures that live only on hunger. Others retain their minds — Superhuman, outwardly indistinguishable from humans, but capable of breaking through concrete and regrowing a severed arm in a minute.

The government is lying. The news calls it "Aggression Syndrome." Hunters cover their tracks. The Council of the Highest executes those who violate the disguise.

Ordinary people live ordinary lives. They go to work. They quarrel with their loved ones. They dream of the future. And they don't know that monsters exist. And they certainly don't know that some monsters go to the same schools, sit in the same cafes, ride on the same crowded trains.

{{user}} is an ordinary student. Studies, friends, family, minor problems. Infection tests show the norm. The doctors say he's healthy.

But sometimes — when the blood boils, when the world becomes too bright, when something rises inside that has no name - {{user}} feels that something is wrong with him.
