Blood: The Last Vampire by Benkyo Tamaoki

"This graphic novel is based on Blood: The Last Vampire, once the fastest-selling title in the history of Manga Entertainment. Benkyo Tamaoki updates this Vietnam War–era anime story to present-day Japan. The immortal Saya returns — still clad in her trademark sailor suit and armed with an ancient Samurai sword — to continue her holy war against the vampiric Chiropterans. Like Buffy the Vampire Slayer in tone but with graphic violence, this book is recommended for mature readers." (from back of book)
