If you liked the Blast of Tempest anime, the Anime-Planet community thinks you'd like:
While Blast of Tempest was about magic , Darker than Black is about magic in some sense but they use contracters that have to do something after they use power. If you like action then i reccomend this
Looking for a change, Mikado moves from the countryside to bustling Ikebukuro to attend the same high school as his best friend, Masaomi. Though navigating a new school and friendships can prove tough by itself, Mikado also finds an overwhelming number of new delights and dangers in the district he now calls home. From a friendly Russian sushi bar to the violent color gangs, to even an urban legend in the form of a black motorcycle rider, each resident of Ikebukuro is unique and frightening. But the town is smaller than it seems at first, and these strange events appear to be connected. Will the growing storm sweep up the transplanted country boy and his friends or will Mikado find himself at the center of a dramatic change for Tokyo?
Both animes revolve around secrets between friends that will lead to endeavors in their lives. Both animes also revolve around 2 male protagonists and one female protagonist. While Durarara!! is based more around a normal human life (to an extent), Blast on Tempest is about these protagonists saving the world while trying to understand themselves. They both have humor but, Blast on Tempest has more intellectual humor to it.
In the near future, the outbreak of a terrible disease called the Apocolypse Virus places Japan under the military rule of a global organization called the GHQ - a group tasked with checking the spread of the virus and administering vaccinations. Apathetic high school student Shuu Ouma lives in Tokyo, spending his days editing videos and trying to be left alone. But things change when he meets the beautiful pop idol, Inori, who is on the run from GHQ soldiers. While trying to save her from her captors, he acquires a mysterious power called the Void Gene that allows him to pull items or weapons from anyone under the age of seventeen. Now, Shuu must decide whether to join the efforts of the well-funded radical terrorist group "Funeral Parlor" and fight against the GHQ, or shrug off his newfound power and resume his normal life - assuming that either the GHQ or Funeral Parlor's charismatic leader, Gai, will let him.
1) Both animes are set in apocalyptic Japan
2) Both apocalypses are caused by a source that makes people´s body turn into crystal/metal
3) Main characters are bound by friendship
4) Some higher power (state, the powerful) is trying to suppress/kill them
both animes are very similar to each other, its just that Guilty crown has mechas X Zetsuen has magic
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.

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.
