There was an extremely limited number of ways to kill a vampire. After turning, each vampire learned these methods by heart. Sunlight, fire, and staking with wood that was older than the vampire itself. The only additional way to [i]subdue[/i] a vampire was to take off its head, and that would only last as long as the head and body were kept separate. 

So, Kaori believed they held the advantage. When a vampire fell to a bite or a bullet, they would likely stand again in the next few moments. The added attack wasn't enough to pull her focus from the scent of celestial blood. Not until flame erupted into the space. She felt the heat as if it were coming at her in slow motion. It took her less than a second to spring from the floor onto a nearby bar counter. Thanks to their natural speed, a good number of the vampires had dove or otherwise dodged the path of the flames, but a few who had been trapped in chaos were suddenly lit up like a number of small Christmas trees. The agonizing screams reached her ears seconds before the scent of burning flesh, and that was enough to slice through her blood-dazed mind like a blade. 

Her concentration returned to her forcefully, strengthened by her sudden enragement. Not all of these - actually barely any of these - were her friends. But they were her people. Her [i]kind.[/i] And they were being burned alive. 

Her red-wine eyes darted about the space. She zeroed in on the source of the fire. She slipped a hand into her boot and pulled out a small, curved blade with an ornate handle. She took a running start across the bar, zipping over its length and diving from the edge. It was [i]just[/i] enough momentum to put her above the flame. She could feel the sting of heat against her skin and smelled the singe  of a few strands of her long, shiny hair. [i]How dare they.[/i]

With her fist curled around the handle of her blade, she turned her body enough to swing her arm around and down as she came back towards earth, aiming a swift [i]swipe[/i] of the sharpened blade at the back of the living flamethrower and landing in a low crouch behind him.
