This Gyaru's Got a Thing for...Vampire Hunters?! Volume 1

"Deadly monsters who stalked innocents in the night and preyed upon them in secret, versus the select few who used mysterious powers honed by intense training and determination to battle their foes... This was the world of bloodshed that Ginka Shijunana knew and lived for—an endless clash between vampires and vampire hunters—until one final victory ended their war. Ginka decides to become a normal high school student now that her vampire hunting days are over, but her combat skills are no match for the challenges of everyday interactions with other teenagers. Still, she hits it off with the flashy and fashionable gyaru Ruka Moriki. When remnants of Ginka’s old life start to mysteriously reappear, however, will she pull Ruka into the darkness with her? Or will Ruka help her remain in the light? Find out all of this and more in the exciting first volume of This Gyaru’s Got a Thing for...Vampire Hunters?!"
