CRIPPLE -A Hidden king

A world that you will be scared of, a nightmare that you never want to see.
This story of the earth that turned into hell, when those creatures come to reality. But now after so many years, and yes after so many death of humans, of course, humans .. I guess are born to die Lol. My bad
It begins from Unnatural Academy, which was created by witches to reconciles those dogs and cats or I say those blood enemy werewolves and vampires.
But no one expected, that this time it will just bring another bloody war, even more, worst than before. Even more, blood will be shed in this war, more humans will be terrorized. And the whole world would be his enemy.
