Dueled Blampires

I got going, and neither of us said anything for a while. My knuckles were getting white again, so I started talking. "So you've done one of these duels before?"
"Hai," he said, nodding. "Many times."
"Why?"
Shiro shrugged. "Many reasons. Protect someone. Force something to leave an area in peace. Fight without involving others."
"To the death?"
Shiro nodded. "Many times."
"Guess you're pretty good at it then," I said.
Shiro smiled a little, eyes wrinkling even more. "Always someone better."
"You ever dueled a vampire?"
"Hai. Jade Court. Black Court."
"Jade Court?" I said. "I've never heard that there was such a thing."
"Southeast Asia, China, Japan. Very secretive. But they respect the Accords."
