In the early 21st century, the emergence of an incurable condition known as B-cell growth led some of the affected to become "Sleepers" - people put under statis until a cure could be found. Yuji Kaido is one such Sleeper who awakens, several decades later, to a horrifying new reality. Giant bugs known as Blue have invaded the Earth, eating everything - and everyone - in sight. Now, all Yuji can do is escape from the city with the ones who saved him from his inevitable death, and make their way towards Second Earth: mankind's new home in space.
While the nations of the world are trying to abolish warfare and the existence of armies, private companies are creating their own armies. The Kuryu group has been trying to create the perfect weapon; human beings capable of mastering their "mind shadow" named Vajura. They were hoping for an edge, but the experiment seemingly went wrong. However many years later a strange young girl named Elaine escapes the Kuryu research facility. Confronted with hostile gangs, hunted by cybernetic agents, and other strange members of the Kuryu group she is forced to become the Genocyber, the first Vajura. Confronted again and again with the experiments of the Kyuryu group and the inhumanities of mankind, she has no choice but to continue to fight, but at what cost?
Even though Genocyber is much older, whilst watching Blue Gender: The Warrior I felt that they have a few similarities. Both involve monsters in a post-apocalytic world and there is plenty of gory violence. If you like that sort of thing try these animes out.
