It is set in England in an imaginary era. It begins with a chaotic dinner party and a bizarre journey of a young man and a mysterious girl (?). Vampires and werewolves appeared one after another... The journey back to his hometown was full of unusual things, but the real story didn't really begin until he entered London.
It is still unknown whether the struggle that has lasted for more than two hundred years will end this time; and how the contract with the director of a British agency forty years ago will change the next scene...
