A giant wall looms over Tokyo, shielding the city from a dangerous otherworld called the 'Hell's Gate'. Within the city, things are no less terrifying because Contractors, psychopathic killers with phenomenal powers, have started to appear. These killers are compelled to pay a price every time they use their powers, often in the form of a meaningless or painful task. As their deadly habits rack up a gruesome death toll, Kirihara Misaki and her team from the Foreign Affairs Public Security struggle to solve the cases and bring the Contractors under control. Their task is further confounded by the interference of a masked individual they title Messier Code BK201, a man with abilities that allow him to fight and defeat the Contractors. Who is this BK201? How can the Contractors be stopped permanently? And what does the appearance of the Hell's Gate mean for the people of Tokyo?
In post-war Japan, the nation remains unsettled and crime is as big a problem as ever.

However, in spite of his poor reputation, Shinjurou continues to work on every case he's recruited to with his mysterious assistant Inga.

Cross Academy is a school with a difference: in a unique and experimental setup designed by the headmaster, it has a Day Class consisting of ordinary humans and a Night Class filled with vampires. Yuki Cross and her friend Zero Kiryu are school prefects whose job it is to make sure the secret of the Night Class is always safe; they patrol the school grounds at night and supervise the switchover of classes at dawn and dusk to prevent any 'accidents' from happening. While Zero is suspicious of vampires and hates the idea of sharing the same space as them, Yuki admires the Night Class for their beauty and sophistication; she is especially intrigued by their charming leader, Kaname, because he once saved her life. However, as Yuki quickly learns, not all vampires are amiable like the Night Class, and as terrible events unfold, Yuki must ask herself whether in a world where vampires are the hunters and humans are the prey, peaceful coexistence can really be achieved.
Both anime have almost identicale doses of a dark mysterious feel. The cast of characters have almost an identicle level of character development as well. They also both deal with the supernatural, although one is Vampires and the Other is Super Powers. And they both seem like small plots that branch out to matter with something bigger. They even had the same type of endings. It is hard to put into words why, but the entire time I was watching one I was reminded strongly of the other. I really think you enjoy one, you'll enjoy both.
