I have decided to rewatch the Black Blood Brothers series. So far I have seen episodes one through four. We have met Jiro Mochizuki. He is an old vampire, an old blood. He is also known as the Silver Blade. Apparently Jiro has made it his mission to eliminate the Kowloon Children.The Kowloon Children are some powerful vampires. They can quickly turn humans to vampires and control them. A group of Kowloon Children abducted Jiro's younger brother. Jiro used up all his strength defending against these vampire. Luckily Mimiko, a compromiser, gave her blood to Jiro to energize him.
Mimiko experienced the resonance, where she could read the mind of Jiro because her blood flowed through him. I don't know the full story. But it appears that compromisers negotiate agreements between the humans in power and vampires that want safe harbor in the Special Zone.
