Vampire Juuji Kai by Shirodaira Kyou & Kimura Yuri
I am just trying to promote a manga i like Vampire Juuji Kai. Its a great manga, great plot, never boring. You can download it at http://www.sacred-tear.hostanime.com/vjk/manga.html . I dont want to give to much info, other than its great. I am hoping that if enough ppl like it, they can do Scanlations of it. You won't be disappointed, it has so many plot twists.
