This is an old handed down story which can also be found in libraries of elementary schools. It starts with this phrase. In a certain place, there was a world where vampires who never age live. Not a single human knows about this world. Furthermore, the main characters of this story Sakurako and Komachi lived there too. But in that world was an unkind, cruel and selfish count who used all means to get what he wanted to amuse him. That was because he was very bored. The count found another thing he wanted and did everything to obtain it.
