The Crimson King and the Rise of the Blood M...
Three hundred years after a nuclear war humanity has finally been able to reunite and establish peace once again. However, the consequenes of the war still lurk in the form of radioactivity. Slowly, people start beeing affected by the radioactivity, ad soon mutations arise.
These mutations, altough somewhat rare, are mostly detrimental to ones health and kill most of the humans who are born with them.
However, there are a select few who survive the mutations to their DNA and develop abilities wich could only be described as super-human.
These abilities range from simple ones, to extremely complex and powerful ones, like the ability to control certain types of energy that nobody even new existed.
The relatively newly established nations, quickly realizing the potential of these exceeds, and seeking more military power in fear of a new war, build schools and training facilities to prepare them for battle and to prevent a possible revolt from these "super-humans".
Aku and his twin sister Mazuno, are to of these mutated humans, if they can even be reffered to as "human".
But having so much power comes at a cost as the fear other people have of them causes them to be hunted by the governament before they can even be admitted into one of these schools which only happens at the age of 16.
Quick disclamer: I still don't know about the "romance" part so please don't come in expecting it. I might take the tag out later.
