If you liked the Blast of Tempest anime, the Anime-Planet community thinks you'd like:
Yuki is a disaffected middle school boy who has no dreams or goals in life; in fact, the only thing he has is his diary. Writing down everything he observes and documenting every thought, the young boy uses it as an outlet for his imagination. One morning, however, Yuki wakes up to find his cell phone filled with diary entries for the next ninety days. Thinking nothing of it, he continues his morning until he begins to realize that everything on his phone is rapidly coming to pass, and it isn't just mere coincidence. Now, Yuki suddenly finds himself thrust into a survival game against other future diary owners to become the new Lord of Time.
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!).
Sion is intelligent, highly educated and lives a privileged life within the walls of No. 6, one of six city-states that was built after the world was destroyed from war. But Sion's comfortable existence changes forever when he meets Nezumi, an escaped convict, on the eve of his twelfth birthday. Due to his assistance in keeping Nezumi safe, Sion loses his rights and is forced to live in the lower town, where he becomes a normal citizen. Four years later, Sion finds himself back in Nezumi's company and in the midst of a dangerous conspiracy that leaves a trail of bodies in its wake. What is really going on in No. 6?
Two young men get wrapped up in strange happenings that threaten their lives and the world around them. The main characters in both series are friends, but at the same time, they're entirely different. What they want is different. How they want to achieve it goes against the others beliefs. Can they put their differences aside to work together and save the world, or will their bonds fall apart? Will there be betrayal, or worse yet, death? You have to watch both to find out. Zetsuen no Tempest and No. 6 are not entirely identical, but when it comes to their characters, they're quite similar.
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 deal with time travel, confusing powers with convoluted storylines, and are set in contemporary worlds that are in danger of being destroyed.
They also are both very similar in how the dramatic and comedic elements of their stories are told. And are scored with music that sounds unique and hauntingly beautiful.
I would say that Noein is the better anime out of the two, because while both are extremely convoluted, Blast of Tempest gets pretty rushed in the third act and unravels quite a bit. In terms of animation Blast of Tempest is a lot cleaner and flows better with a better use of color (I'm sure uses more computer animation techniques). Noein seems to have more of a hand drawn look (especially during action), which isn't bad, but it can be a little bit distracting and take me out of the story a bit.
On a tragic night in Neo Verona, the Capulet family is murdered by Montague and the country is seized. The only Capulet survivor is the child Juliet, who is rescued by loyal knights. Fourteen years later, people in Neo Verona live in poverty and fear. Juliet has spent her life in hiding, and in disguise as the male Red Whirlwind, secretly fighting Neo Verona’s oppression. On one of her secret adventures, she is helped by Romeo and falls in love. Finally, on one fateful day, Juliet’s family reveals her heritage and their desire for her to reclaim her title and rescue Neo Verona from tyranny. Meanwhile, Juliet also discovers that Romeo is the son of her worst enemy. Can Juliet rescue Neo Verona and kill the father of the man she loves?
Both series have a storyline based on shakespears novels
Like Romeo x Juliet is based on the shakespear novel Romeo & Juliet.
Zetsuen no tempest is based on the shakespear novels Hamlet & The Tempest.
The mystery of "The Blade Children" is a secret which has remained well-hidden, and has cost some their lives. After Narumi Ayumu's brother disappears in a search for the answer, Narumi is forced to unravel this mystery for himself. Join him in his investigation which will lead him to the secrets of the Blade Children, and to tests of skill which may prove to be fatal.
In both shows, the characters are thrown into complicated situations where they must use reason to solve crimes, rescue themselves from a death trap, and question everything they thought to be true. If you enjoy fighting with logic in life or death situations, then both of these shows are for you.
