The Black Dragon Emperor

Male Reader x Yandere Highschool DxD Harem.
Y/N Hyoudou was a normal teenage boy with a normal life..... that's atleast what everybody else thinks. In reality, his life was anything but normal. His real name was Y/N Wesker. He wasn't exactly a normal human. He was enhanced with a virus called the 'Wesker Virus'. It gave him abilities beyond that of an average human. When he was still a small kid, he was raised in an orphan. The other kids didn't like him and bullied him for being 'different'. Then after a while, he got adopted by the Hyoudou family. He thought that finally after all this time, that somebody would love him.... he was so wrong. His adoptive family abused him, insulted him and many other things. One day he got kidnapped and was tested on by scientists. Their goal was to create the ultimate super soldier and they succeeded....... but payed with their lives. A few years later, a strange individual appeared and killed Devils, Fallen Angels and Angels on first sight. It was merciless and showed no remorse. The being calls itself the 'True Emperor'. In secret, the True Emperor is Y/N, who escaped the experiments. After he escaped, he began a new life. When he meets a group of Devils, will he kill them? Or will he eventually show them mercy? And what will the Devils do, to get what they want? Only one way to find out.
