Jiro is traveling with his younger brother Kotaro to the Special Zone, a place where vampires live freely in peace alongside humans. But the brothers find themselves in the midst of a battle between human soldiers, vampiric refugees and the re-emergence of the Kowloon Children. Assisted by Mimiko, a negotiator between their species, Jiro will try to make sense of the chaos which surrounds them before they are caught up in it and destroyed.

Jiro and Kotaro have finally made it into the Special Zone, but they soon find their welcome less than promising. With his reputation as the hero of the savage wars, the presence of the Silver Sword has raised quite a bit of interest. It seems the vampire attracts too much trouble - and the discovery of Kowloon Children behind the barrier may soon prove just how much trouble Jiro can attract.

Unwelcome and unwanted, Jiro decides to flee the Special Zone with his brother. But Kotaro goes missing and chaos is fast breaking in the city. Cassa's nefarious plan is revealed at last: to search out the rumored Eleventh Yard under cover of the confusion she created.

It's been a decade since the sacred war between humans and vampires. The rise of the Kowloon Bloodline, a new breed of monsters bearing an infectious bite, set the streets ablaze under the reign of their king. Humanity had never witnessed such pure, animalistic brutality.
