Kinji is a junior at a high school for mercenaries. He just wants to be normal, but his secret condition—he turns into an ace killer when he's turned on by the female form—triggers a fiery transfer student's unrelenting desire to make him her partner. 

Ever wondered what it would be like to become a mercenary and save the world? Well I have and I was quite interested in the plot synopsis, so I watched it and I wasn't disappointed. The action was solid throughout the whole thing and so I enjoyed it, however the plot couldn't be more generic. Bad guy, mystery, Big boss , beat big boss, The end. That's basically the plot and so it was a bit of a let down in total. 

The animation is not so good. The character sketches are good for the most part, the coloring scheme is good. But, the animation fares poorly, for one the scenes are not so fluid, they seem cut-off sometimes and another the angles are definitely not the best they could have given. I don't think they spent much in the animation department cause although the guns and characters are well made the action scenes don't come out as great. The backgrounds aren't spectacular either.

The sound department is fairly better than the others. I don't have very sharp ears to analyze the quality of voice-acting and BGM and grade it qualitatively but I consider most of the voice acting as good and the BGM nice though not spectacular. The OP seemed good to me, the ED was good and had a great accompanying animated scene. 

The main characters are basically the descendants of all the famous families in japan in one way or another.

-->The male lead which have a certain circumstance called "Hysteria mode" which turn him into a super whenever he's sexually excited, this plot, some says cliche which the protagonist gets power from something perverted, there for, he's a pervert. But actually he's not a pervert at all since the beginning he already state the fact that he had a hard time dealing with girls and they overlooked that.

--> The female leads, which are descendants of Sherlock Holmes, Arsene Lupin and a long line of Miko(s). As for this, they says it cannot be related since the design are much too different, well, I've got a thing or two to say about that. Originally, both Sherlock Holmes and Arsene Lupin are fictional character which were created by Conan Doyle and Maurice Leblanc so what's wrong with creating the descendants which are different from them?! Not always do the descendants have to be better than the head of the family. As for the Miko(s)'s descendant, this character is totally fictional so I don't have anything to say.

Overall, even though the anime may not have been original, I would say its definitely worth your time to check it out. If you have disliked the past J.C. Staff tsundere romances such as Zero no Tsukaima or Shakugan no Shana, this one probably won't be any different. For some inexplicable reason, Hidan no Aria is an anime I enjoyed a lot more than I thought I would based on my impressions from the reviews. I give enjoyment a 9 and overall rating of 9. It may not have been ground-breaking or moving or a deep plot, but it had all the elements that I was watching for which was basically action, romance, and just that kind of casual anime to watch for the cutesy stuff and comedy. Comedy is very well-fitted with this anime.
