Demons are escaping from the underworld, and causing much havoc on the population. Possessing both human bodies and artifacts alike, the demons are inconspicuously forcing people to commit murders; the demons must be stopped! The task of returning – or exterminating – the offenders lies with Enma, Kapaeru, and the talking witch hat Shapoji; can Enma and the gang banish the demons before things get out of hand?
For Kouta and Yuka, finding the bloody naked young girl on the beach would change their lives forever, for better or for worse. Unable to speak or function as a normal human being, she is named Nyu by the duo, and taken into their home in an effort to save her. But what neither teenager knows is that this innocent young girl is actually a killing machine -- an experiment gone terribly wrong -- and it is only a matter of time before the murderer in her awakens again...
BLOOD AND BOOBS! Also some dark psychological themes. I assume that's why you liked either Elfen Lied or Demon Prince Enma, right? While Enma is a horror series and Elfen has a harem tossed in for good measure (or not, blech), I still think they'd attract the same sorts of audience.
Tarou has dreams - distressing dreams, related to the trauma he suffered as a child. His dreams and visions disturb his ease of mind, constantly reminding him of the darkness of his fear at the time he lost his sister all those years ago. He relives the fear, but can't recall any of the details of the time. Now, a new transfer student, Masayuki, takes an interest in Tarou's troubled past, as well as their school mate Makoto's connection to the dark incident. Under his persistence, the three boys end up visiting the site where Tarou was held hostage as a child: a decrepit hospital beyond the dam. The three venture forward to face their pasts and fears, unsuspecting of the bizarre world they are about to enter...
Both explore the boundary between madness and sanity as events unfold, seemingly normal and also seemingly supernatural. What is real and what is not becomes less and less important than figuring out how to escape.
While discussing her past with Master at the Dandy cafe, Sawawa is completely unaware of the trouble brewing back at Hime’s mansion. Hiro’s flame of life seems to be slowly ebbing away, Reiri has lost the vampiric power of flight, and half-breed Liza can no longer use her super-strength. As if being helpless isn’t enough, enemies of the past show themselves once more; a spectre of a familiar werewolf bears his fangs, a giant shark drifts through the darkened corridors and a headless horseman bounds through the walls. What exactly is going on, and why is Hime so calm?
In the streets of Tokyo, the nightbreed walk as humans, preying on innocent lives and feasting on innocent blood. There is one man who would put a stop to this: Shido, the Night Walker, whose blood is made up of the very thing he aims to protect against: the nightbreed. Along with his co-worker Yayoi, a green fairy named Guni and a clever young secretary named Riho, Shido and his detective agency take cases that would be otherwise missed and forgotten, to seek out the nightbreed and send them from whence they came...
DPE and NightWalker are both about a select group of persons, in which all or most individuals are no ordinary humans. They both deal with monsters, which escaped from ''the dark side'' and cause terror among human society. A decent amount of gore is also present in both.
In the streets of Tokyo, a new menace has surfaced: Shounen Bat, a young boy who wears golden roller skates and a baseball cap, and likes to whack people on the head with a golden baseball bat. These seemingly unconnected and random attacks soon become a police investigation... but after all is said and done, is there a pattern to this chaos?
Demon Prince Enma and Paranoia Agent have quite a number of things in common. There are some similar themes like dark side of japanese culture and the villains in both series (demons in DPD and Shounen Bat in PA) tend to feed on the darkness found in human heart (but it doesn't work exactly the same in both shows). If you enjoyed one of those shows the other might prove interesting as well.
