A vampire action show that actually cares about the ceasefire more than the war. Jiro's caught between human soldiers and the very monsters he's spent a decade protecting, forced to watch the peace he fought for collapse the moment someone decides it's inconvenient. The Silver Blade comes out not because good is fighting evil, but because both sides have already decided the other one doesn't deserve to live.

Ten years after a war that set the streets ablaze through the infectious bite of the Kowloon Bloodline, the vampire war hero Jirou Mochizuki, called the Silver Blade, heads to the Special Zone with his younger brother Kotarou. The Zone is meant to be a refuge where vampires and humans share a home, but that peace is starting to crack. Fighting breaks out between vampire migrants and the Zone's human forces, and Kowloon Children join the chaos. Meanwhile, an old enemy's conspiracy is taking shape. To protect what matters most to him, Jirou will need his new ally Mimiko Katsuragi, known as the Compromiser, and the strength of his ancient bloodline. The show mixes supernatural action and fantasy with a streak of comedy.
