Quote:

Original Post from Mangaupdates Kenzaki Shinichi is the leader of the Anti-Vector Task Squad. He's in charge of hunting down Vectors, humans that carry with them the deadly Resurrection Deficiency Syndrome, a disease that can keep someone from resurrecting when they die.

Ruthless action girls, cool males protagonist, immortality and infectious disease... sound familiar, right? But that's not it at all. This series is very unique and original. It's about a world where immortals are majority and mortals are minority who are hunted down because they can spread their mortality to immortals. If you love action and mysteries, you gotta love this.
