Practically everything there is to like about Mirai Nikki can be found in 11 eyes as well. Mirai Nikki is probably the better show because there are more episodes which make for a deeper storyline. If you liked either one, you'll definitely like the other.
Hakaze, princess of the Kusaribe mage clan, has been betrayed and marooned on an island by her own people. They seek to revive the Tree of Exodus, an incomprehensibly powerful entity of alien origin, to save the world from the tyranny of its antithesis: the Tree of Genesis that powers their magic. Hakaze, however, believes their efforts put humanity in jeopardy; and with her power limited, she can only reach out to the world to beg for aid. Her call reaches Mahiro Fuwa, a young man grieving the mysterious death of his sister, Aika. He and his friend Yoshino agree to help - on the condition that Hakaze track down Aika's killer with her magic. The deal is made, and the battle that will determine civilization's fate is begun: but who will play the part of its villain, and who its savior?
Mirai Nikki and Blast of Tempest both start out in the modern world. Slowly, they both incorporate surreal elements.
By the end of the first episodes, we are fully engulfed in these supernatural worlds. However, the rules of the anime manage to ground these other worldly elements.
Both forge amazing character connections, and are more cerebral, despite the fair amount of action each contains. If you like one, you will likely enjoy the other, although Mirai Nikki is certainly the darker of the two.
Finally, both feature enough twists and turns to keep you entertained until the satisfying conclusions (make sure to check out the OVA for Mirai Nikki!).
Takumi is a reclusive otaku who wants nothing more than to be left alone to play online games and watch anime. He only attends the minimum necessary to pass his classes, and rarely leaves his cramped room except to purchase the newest figurines. One evening, while Takumi is chatting online with his friend "Grim," a stranger called "Shogun" joins the channel and, after "Grim" leaves, posts a series of disturbing photographs depicting a man impaled to a wall with metal stakes. The following day, Takumi is horrified when he wanders into an alley and once again sees Shogun’s images – but this time, the gruesome scene is reality. From then on, Takumi sees the world through a new set of eyes; imaginary delusions meld with reality, and he isn't sure who he can trust. With suspicions and confusion at every turn, Takumi must struggle to determine what's going on - but most importantly, whose eyes are those eyes?
Much to the annoyance of Kei, he and his childhood friend Katou have died, having been torn apart by a train. But rather than finding themselves at the gates of heaven, the duo materialize in a room full of strangers and a giant black sphere known as GANTZ. As if dying once wasn’t bad enough, the occupants of the room are then forced to embark on dangerous missions to kill strange aliens; missions that very few return from. Now, Kei, Katou, and a well-endowed friend must fight for their freedom with an arsenal of guns, high powered suits, and a very low chance of survival.
Both of them are kind of Survival, Gore (more explicit on Gantz) and the psichological stuff. Each chapter of Gantz its unforgetable, and you must see it so you can understand the story and connect it. THe same way with Mirai Nikki,each chapter is somehow related with each other and in much of them exist a suspense and you want to find out who is behind the big thing!Really, I recommend you both of them, if you are a fan of gore animes ^^
When the infected approached Rei and Takashi's school, it led to a gruesome blood bath that left the majority of students and staff dead or turned into the zombie-like monsters that have spread throughout the world. Together with a handful of other survivors, Rei and Takashi set forth to find their families in a world that is rapidly detoriating. Governments have collapsed, the killer disease is out of control, and people everywhere are trying their best to simply live through each day...
If you like one of these animes, you will probably like the other as both series handle their fighting scenes in a very epic way. Art is very detailed and can make certain characters look creepy at times. There is also a good amount of drama that happens between characters and even some romance.
