Ep: 69 Blood Plus Anime Review

Blood Plus, revolved around a young girl named Saya Otonashi, the pure blooded queen of a race of super beings called Chiropteran. The Chiropteran may look like mindless, blood sucking animals on the surface, but they have the potential of becoming the next dominate species on the planet earth. 

As she fights to save humanity from the Chiropteran threat, Saya’s true mission of finding and killing her twin sister, Diva, also a queen of the Chiropteran and by far the greatest threat to humanity, takes precedence above all else.
