Throughout the passage of time and the shifts in backgrounds, a particular war continues to leave its mark on history, extending its influence into the modern world. There are two major groups involved in the ensuring war. The first group consists of monsters known as Chiropterans who can change their appearances into that of human beings. They are actually immortals who feed on the blood of the living. The second group is an organisation known as the \"Red Shield\", formed to track down these monsters and exterminate them. Otonashi Saya is a high-school girl who lives a peaceful life with her family. The only problem is, she has no recollections of her life beyond that of the past year.

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.
