Hidan no Aria

Kinji Tōyama is a student at Tokyo Butei High, a universal educational facility. At this school, students undertake special training in order to learn the path of the Butei, which is a national qualification permitting its holders to arm themselves and capture criminals. The Butei were established to counter the worsening crime conditions, with training in various specialized fields. One day, Kinji decides to quit the Academy, until he is mysteriously attacked by the Butei Killer, a notorious criminal hunting down Butei with passion. The elite Assault prodigy Aria H. Kanzaki comes to his rescue. From this point on, Kinji's future as a Butei changes drastically.

The world of Hidan no Aria is one where the Butei, an elite international martial organisation, trains its members at the high school level. That’s right. In this world, international treaties on child labour are unheard of, and hundreds of parents see no issue with sending their children to a school where the use of firearms is not only commonplace, but required. Furthermore, the students of Tokyo Butei High—quite unlike my high school classmates, most of whom, by the time graduation rolled around, had yet to master the delicate art of pissing straight—perform incredibly well in this environment. 

Oh, but it’s not just the coursework they have to worry about. Butei High students must apply their lessons to real life when they are targeted by the Butei Killer—a criminal who sends high-speed Saw-esque murder puzzles after the teenage students. This individual has yet to be apprehended, as Butei graduates and all other law enforcement agents have better things to do than bother with a serial criminal with a rigidly-defined M.O. who regularly targets minors, and endangers civilians in the process. 

I'm not saying the anime is bad, but well, it is still enjoyable. As nonsensical and clichéd as everything about this anime was there was plenty of amusement to be found in watching the characters act this way.
