This is a wiki based on the manga, Blood Parade by Karasawa Kazuyoshi which was was released in 2011. Genre: Horror, Shounen, Supernatural.
Blood Parade follows the story of Gil Mayford, who works for the International Security Section (a.k.a ISS). The ISS is a special UN funded organization whose duty is to seek out and destroy mankind's greatest enemy - the vampire. Fueled by a burning hate towards the vampire who killed his family, Gil is on the road to becoming an apostle, one of those within ISS responsible for eliminating vampires. He has successfully passed the trials and exams needed to become one of the Twelve Apostles. In order to become an apostle, Gil needs to pass one final test, kill a vampire. For this, he is assigned an Escudo, or a "shield" - the young and beautiful girl named Luna. Once deployed to the area where a vampire hides, Gil learned how truly powerful and deadly they can be. As a result, he nearly loses his life; in fact, if not for Luna's intervention, he would have. But instead, in the process, he learns her true identity. To Gil's shock and horror, she is in fact a vampire; and not only that, but the Pure Blood, the one who created the vampire race. The one he believes to be responsible for the death of his family when he was young.
After the mission, Gil is informed by the Director of ISS that Luna chose to work with them so she could aid in the elimination the vampires. Still, though, this can't dispel Gil's grudge against Luna and her kind. Gil is reluctant to put his trust in her, but if he is to have any hope of unraveling the mystery surrounding his parents' murder, he will have no choice but to accepts Luna's help - even if it kills him.
