In feudal Japan, Kurou and his servant Benkei are fleeing from Kurou's elder brother, who has recently ascended to the throne. In a forest, they come across a house and a strange woman by the name of Kuromitsu, who agrees to harbor them under one condition: that they do not peer into the inner chambers. Soon, they are attacked by the Red Army; they are searching for Kuromitsu, whose blood holds immortality. Fatally wounded, Kurou drinks some of Kuromitsu's blood and gains immortality along with strange abilities; but shortly after, Kurou is seemingly decapitated and wakes up centuries later in a ruined city. In this twisted future the Red Army is omnipresent and still searching for Kuromitsu’s blood, while a rebel army seeks to keep them from acquiring it. With threats at every turn and fueled by his obsession, Kurou sets forth to find Kuromitsu and seek his revenge on the Red Army.
In the future, a system called Sibyl presides over the country and provides order to every facet of life. It dictates which job fields citizens should go into based on aptitude tests, and can even read each resident's mental state and predict which ones are likely to commit crimes in the future. Fresh from exams, Akane Tsunemori is beginning her career as an Inspector, a specialized police officer who works to apprehend these latent criminals and stop crimes before they happen. But not all that get caught are eliminated or jailed, some join the police force as Enforcers to provide insight into criminals’ minds, and Akane is warned not to get too close to them, as they're considered little more than hunting dogs. Though skeptical of this advice, and Sibyl's judgement, Akane is determined to work together with her Enforcers to protect the peace of her city and its inhabitants.
Both series have a foreboding, dark vibe to them. Though placed in very different worlds, the theme shared between them is a disturbing mystery shrouded from common knowledge. Elfen Lied is more bloody, but both provide action and intensity with an enticing story.
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.
Vampire Knight is an anime mostly based on romance with action as well. With a rather surprising turn of events in the series, I highly recommend that you watch this anime. It is not as bloody, disturbing, or awesome as Elfen Lied (then again not much is), but it is still a great anime with a very good plot line.
26 years ago, something terrible happened in a middle school’s third year classroom. A popular, talented student named Misaki suddenly died, and the ramifications of that incident have caused each third year class since then to live in fear. It is now 1998, and Kouchi Sakakibara has just transferred into the notorious classroom, curious about the mysterious secret that his peers are hiding from him. He’s drawn to one enigmatic girl named Mei Misaki, a quiet student who wears an eye patch and warns him about getting involved with her, and continues to seek her out against the pleas of his classmates. And that’s when people begin to violently die...
Both Another and Elfen Lied have a slightly haunting feel to them, and an element of questioning morality in situations where murder(s) is concerned. Another and Elfen Lied's female protagonists are received in similar ways by other characters, and both have deeper pasts which are explored as each series progressed.
There is bloodshed in both of these series, so fans of yandere might appreciate this element(!)
Keitaro Urashima is somewhat of a failure. In order to fulfill a promise he made to a girl fifteen years ago, he has tried time and again to get into Tokyo U but has never managed to pass the exam. However, fate smiles upon him and he ends up working for his aunt, managing an all-girls dorm! Living with the feral Kaolla, the timid Shinobu, the sake-loving Mitsune, the blade mistress Motoko and the punch-happy Naru, can Keitaro keep his focus and keep his promise? And will he ever end up meeting that girl from his past?
This may be an unexpected suggestion. But if you subtract the blood and gore and flying limbs, and other objectional topics such as sadism, child abuse, and torturous "research", Elfen Lied is an ecchi harem anime at heart, with a hint at comedy. It reminds of Love Hina in how one socially awkward virgin guy lives together with a number of young girls in a traditional-style house, with all complications that could arise from this fact.
