If you liked the Shadow Star Narutaru anime, the Anime-Planet community thinks you'd like:
Amidst a beautiful sunset, Shu is violently whisked away to a grim future devoid of water, and empty of hope; a place where children are forced to become soldiers, and kill countless others in the name of King Hamdo. Shu's companion is a mysterious girl named La La Ru, who may hold the key to survival. Now, he must concentrate on the only things that matter: escaping Hellywood, and finding a way home.
Both shows feature overly optimistic characters who seem to be oblivious to the constant death around them. Both shows are drawn in a happy-looking style and could almost fool you into thinking they are upbeat shows, yet prominently feature death, attempted suicide, rape, intense bullying and children mercilessly killing other children.
The plot of Shadow Star Narutaru and Now and Then, Here and There differs considerably but they both feature a very young and highly optimistic led that must face all sorts of ordeals. In both there are horrible events that befall children and force them to kill one another. The violence in SSN is mostly of a psychological nature and comprisesa great doese of insanity while NTHT is more graphic and straight forward. War and harship are the main causes of the traumatic events that take place in NTHT while in SSN there is an impending feeling of paranoia that is never quite explained or dispelled.
If like me, you occasionally like to watch something extremely dark and twisted to brighten your day, I could recommend either or both series to you.
Neither features particularly stunning animation, but both focus entirely on the harrowing story lines. These are two of the darkest and twisted series I think I have ever watched.
Rape, murder and personal strife feature strongly in both and do not make for easy watching, especially in view of the age of the characters involved.
"I have only abandoned my body, I still live here" - are the words emailed to friends of Chisa, several days after her death by suicide. As Lain delves deeper into the world of the "Wired" (also known as the internet), the line between it and reality becomes more and more unclear. Close the world, open the nExt.
Narutaru and Lain have a similar dark and gloomy atmosphere. Not only is the mood dampened, but you'll also run into some plot twists you won't see coming. Narutaru is more disturbing though while Lain has a tad more of a story (if you can understand it, that is :p).
Rumors have it that a monster has appeared over the city, and Yuki would love to catch a glimpse! However, she soon discovers something even more fascinating: a boy named Tetsu not only knows of the monsters, he has a monster pet of his own named Cenco! Yuki is delighted to meet such a creature and tags along with Tetsu to find out more, but soon the two find themselves in the middle of a dangerous conflict with another monster that threatens them and bystanders alike!
Narutaru is way, way more messed up than Cencoroll, but it's impossible to not see the similarities between the two. Both star kids who control various cute yet deadly monsters and end up battling each other. Fans of one will definitely appreciate the other.
NaruTaru is much, much darker than Cencoroll, but they both have the same fighting monster feel. But what sets these two apart from say, Pokemon, is that there's a real sense of danger and consequence in both of these shows. If you liked one you'll like the other.
In the future, a devastating event known as Second Impact has destroyed Tokyo as we know it, giving rise to Tokyo III - a city under siege by mysterious lifeforms known only as Angels. Mankind's only line of defense are the Evangelions, a set man-made machines piloted by a trio of fourteen year-old teenagers, Rei, Shinji, and Asuka. The fate of Japan and the entire world now lie with these three children, though they might not have the power to save the most important thing of all: each other.
Both focus on feelings of kids that face(and use) great power, suffering from it. Both series great psychically, also have some strong, violent moments.
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?
Both Paranoia Agent and Narutaru are strange anime. They have some psychological views into the characters and why they act like they do. This makes them feel very similar.
