Midgar, all-girl academy, would have been notable just for the action of accepting its first and only male student, Yuu Mononobe. But Midgar stands out for much more than that: it's a school exclusive to a group of girls known as D's. Each of them have extremely powerful abilities in generating dark matter and manipulating it into powerful weaponry.

The D's didn't exist twenty-five years ago, and only appeared after a number of mysterious, destructive monsters known as "Dragons" started appearing around the world. Strangely, just as suddenly as they appeared, they vanished. In their destructive wake, some girls started being born with symbols on their bodies and powers similar in nature to those wielded by the Dragons themselves.

Now the D's attend this school, hoping to harness and utilize their powers against the Dragons. Yuu is their latest member and is extraordinary for being the only known male D in existence. Now he must forge relationships with the girls around him, including his long separated sister who attends the school as well, and work with them to investigate and eliminate the threat of the powerful Dragons.


Juuou Mujin no Fafnir adapts the first 3 novels of Tsukasa's light novel series of the same title.

(The Boy, the Dragon, and the ‘D’)

Once upon a time, there lived a strong and dense boy named Yuu and his little sister, both possessing the powers of ‘D’, and they lived in a world where dragons appeared and attacked nearby cities. One day, a very powerful dragon attacked their hometown, the little sister was angry and used her ‘D’ power in an attempt to annihilate it, unfortunately she couldn’t. Then, Yuu steps in and uses his ‘D’ power (i.e. obtained by contract with Yggdrasil) and annihilates the dragon.

Three years later, the boy has grown up and has transferred to Midgar, an ...

Fantasy is a genre that is notorious for being one that is very touchy. Because every fantasy world has its own set of rules and laws, every fantasy story has to explain the world in order for the audience to properly understand. It is because of this requirement that when a series doesn't manage to do this, any given anime can fall flat on its face. It is here where we have Juuou Mujin no Fafnir, a show that falls quite flat on many accounts.

Story (3.00/10): The story of Fafnir is based in an alternate fantasy world. Within this fantasy world, ...

Mixed Feelings
This anime is pretty cliche, as a Harem/Romance/Action/Supernatural anime this is very typical its really lacks pop and most scenes are pretty predictable that you'll know what will happen next. So dont go expecting a whole lot out of it mostly a standard Harem/Romance its similar to Infinite Stratos if you have seen that before, but less ecchi.

Plot: 6/10
A fair plot, similar to Infinite Stratos, but Magic > Mecha. You have supernatural abilities only commonly available to girls. In Juuou Mujin no Fafnir the ability is known as Dragons "D" who attend a school far off on a distant island, but with our male protagonist ...
