If you liked the Mirai Nikki TV anime, the Anime-Planet community thinks you'd like:
Kamba and Shouma Takakura have taken care of their sickly younger sister Himari since their parents disappeared years ago - that is, until the day she died. But as the boys grieve by her hospital bed, Himari sits up, adorned with a strange penguin hat. Suddenly, the three of them are transported to a vibrant world where the hat, using Himari's body as a puppet, charges these brothers with a task: find the Penguin Drum and their sister's life will be saved! Now aided by some odd penguins they received in the mail, the duo must find this mysterious item or risk losing the sister they care for so much. However, they aren't the only ones with their sights on the Penguin Drum, for new enemies await them around every turn, all connected in ways they would have never imagined...
What extent would someone go to in order to change their future? Is the future possible to change or is it a matter of fate? If someone believes in destiny then to change it would be to play god. Mirai Nikki and Mawaru Penguin Drum explore these matters in their own way and both become a rollercoaster full of unforseeable twists and turns. Both are highly recommended.
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.
The Main Characters in both series are exactly the same. The Only Difference is that in Mirai Nikki TV the Main Character is stuck in a Battle royal with psychologically insane people and in Neon Genesis Evangelion the Main Character is Forced to fight Beings of Immense Power surrounded by Psychologically insane people. Both are the same except for the setting.
When Haruka, Yuu and their friends decided to go ghost hunting, they had no idea the "ghosts" they'd find would turn their lives upside down. Black-clad and wielding quantum powers, these knights from the future are after an artifact of immense power that they hope will save their dimension from destruction: the Dragon Torque; and Haruka seems to be the key. As factions within the knights violently disagree on how to proceed, Haruka and the gang are caught up in a fight with the Shangri La, in an existential battle where fates of entire universes are decided.
Both of these anime feature heavy reliance on understanding of causailty and time travel - albeit more relied upon in Noein.
Mirai Nikki includes the linear theory in which when you go back in time you and your past exist in the same spacetime, being able to create a "new future" in which you can both cause and interact with, as well as interact with your past self - something that would clearly cause a paradox, but that's neither here nor there...
Noein uses the theory where there are multiple parallel universes existing at the same time in the same space but out of phase, so as to remain separate. One can visit the paralell world - be it in the future or the past - and can only interact with the surroundings or oneself if in phase with the parallel universe.
If you can understand one you will understand the other.
Encased by trees that are used to make grave markers, Sotoba is a village thought to be surrounded by death - a fact that soon literally becomes the case. One summer, a series of mysterious and untimely fatalities begins to plague the small rural town. With a higher than normal mortality rate for the time of year and each cause of passing remaining unknown, Toshio, the local doctor, and Seishin the temple’s vice chief monk become suspicious and take it upon themselves to investigate. However, as the deaths begin to pile up, more people begin to wonder just what is behind this sudden epidemic; could it have anything to do with the bizarre Kirishiki family that recently moved to the village?
Both Shiki and The Future Dairy are surrounded in death and killing. The Future Dairy as a twisted survival game, while Shiki is just for survival. Both have their moments of pure horror that will have you that will have you glancing over your shoulder for anything that might be lurking in the shadows of your closet. If you like either one, you're most likely going to enjoy the other.
Once the undefeated champion of the street fighting game Bl@ster, Akira now fights for an entirely different cause. Having been framed for murder and given the choice of life in prison or exoneration for a price, he chose to take the latter, heading for the lawless district of Toshima. There, Akira is to fight in Igura, a game where the winner of each match receives special tags, and the loser loses his life. Alongside his longtime friend Keisuke and experienced Igura competitor Rin, Akira must now battle it out in Igura, try to avoid the sadistic enforcers that roam the streets, and complete his mission: to defeat Il Re and take down the drug company Vischio.
Togainu No chi: Survive by fighting other people,so at the end you can fight Il Re and be the King of the city (I dont remember its name)
Mirai Nikki: Survive by fighting other diaries users so you could be the next "god"
A mix of blood, some little comedy scenes and fanservice (some ecchi in Mirai Nikki and yaoi in Togainu) makes both series worthy to be seen.Indeed, if you are a gore fan you would like each othern. ^^
