The Immortal Hero: Alucard

Long before Quirks began to manifest within the human race, the world had many supernatural races roaming the world in large numbers, from fairies watching over the forests to mermaids protecting the sea. They were mainly peaceful and kept to themselves. However, humans made the error of trying to rid the world of these races. They feared the end of humanity at the hands of many of these races. Most of the races were wiped out by humanity. The races that survived went into hiding, waiting for the day when they would finally be able to be accepted by humanity.

The remaining supernatural races had a hierarchy within their kingdoms of fairies, mermaids, dragons, werewolves, and vampires. They had noble families, with the true royals ruling over the specific races. The royal families of each kingdom would unite to form their United Federation. Until peace between the humans and the supernatural is formed, no humans are allowed in their United Federation unless one of the royal families directly gives permission. The supernatural races were allowed to interbreed with each other. However, the royal family of vampires, The Midoriyas, were only able to have one child to continue their bloodline. This child was afflicted with an illness that required him to have a human as a pet to supply him with blood.

Will this be the first step into the age of peace between humanity and the supernatural races? Or will this be the restarting of the war between them? Read to find out.
