Anime Review of Blood+

"Blood+" is a fifty-episode anime series with a timeline that spans from 2005 to the year of 2007. It's a series with a horror and supernatural feel of things. The main character is a young girl named Saya Otonashi with a mysterious past. For numerous reasons, Saya cannot remember anything. However, Saya and her foster brothers are dragged into an adventure that takes them throughout the entire world.

It's revealed that Saya isn't human at all. She was living a normal life until getting attacked by vampiric demons known as the "Chiropterans." Then it turns out that Saya is a special operative for this secret group called Red Shield. The reason being is that Saya's the only person who can actually kill these Chiropterans. It is unknown why her blood is the one thing that can kill these demonic beasts.

As her adoptive father George is kidnapped and transformed, Saya's life is very much shattered. She along with her foster brothers Kai and Riku travel around the world with other Red Shield operatives trying to find out the origins of these beasts, who's creating them, and why they're being creating them in the first place. The closer they get to the truth, the bloodier it becomes. More and more casualties pile up as a result of Saya and the others getting to close to the truth.

It eventually ends up with Saya remember her twin sister Diva who is more diabolical. This adventure also brings Saya to remember who she really is. It turns out that she is almost two-hundred years old and had stopped aging since the age of sixteen. Despite Saya's origins, she looks like an ordinary human teenager. But, she's only able to wander around for a few years before going into thirty-year hibernation.

The adventure isn't just a race to stop Diva's diabolical plans but a race against time. She only has a limited time to stop Diva and the organization supporting her before falling asleep. She has all sorts of abilities such as rapid regeneration. But it comes as a drawback as Saya needs to drink blood and receive blood transfusions regularly to remain healthy.
