Plot During a war called the Hong Kong Crusade, an Old Blood vampire, Jiro Mochizuki, a.k.a. the , fought and defeated the Kowloon king and most of the Kowloon Children. Ten years later, Jiro heads to Hong Kong with his younger brother, Kotaro Mochizuki, in hopes of reaching The Special Zone, a thriving secret city where Vampires live-(which is separate from the human civilized parts of the city). They soon realize that a plan to infiltrate the Special Zone is being hatched by the Kowloon Children survivors. As they travel to The Special Zone, Jiro encounters enemies from the past and new threats that may endanger the safety of the Special Zone including the citizens. Kotaro's abduction, by one of the Kowloon Children, thrusts him even further into the battle. Along the way, he meets a human girl named Mimiko. Kowloon Shock Within the story, during the 1850s, a vampire who would later be known as the Kowloon King emerged in Hong Kong, China and began spreading his lineage to others. The Kowloon Children, as his bloodline came to be known, differed from other bloodlines in that all humans (Or vampires) bitten by a Kowloon Child would become Kowloon Children themselves, even without a direct infusion of that bloodline's blood. The ensuing chaos made the existence of vampires, which until then had been living in secret, known to the entire world. The conflict culminated in the Holy War, a battle in which humans and vampires worked together to exterminate the Kowloon Children. After the crusade, the Special Zone - a city for vampires to live - was established on the sea outside Japan. After the war, it was announced that all vampires had been killed, and most humans were kept ignorant of the existence of the Special Zone. Jiro Mochizuki, who became known as the Silver Blade, is a hero of the Crusade who defeated the Kowloon King, although he lost his lover and was betrayed by a close friend in the process...
