Furthermore, what if those pantsu can explode? Yes, they can go KABOOM! How’s that for a change? Assuming you are still hanging around, let me give this one final piece of advice. Stop reading right here if flying and exploding pantsu is not what you want to see because it only gets much more exciting and chances are you won’t like it (ie. you can drop this show from you list).Now for the rest of us, where should we begin? How about the ordinary lifestyle of the young man, our protagonist of the story, Tomoki Sakurai? All he ever wished from his small town was to live a peaceful and quiet life where he can eat, sleep, and play. He even made a motto for himself, “peace and quiet is the best”. One night under a cherry tree, a pretty angel came falling down toward our hero and that is how his quiet and peaceful life comes to an end. Who might this girl be? Where did she come from? What kind of past did she have? All these questions will propel the story forward and eventually develop into something much more than what anyone would have initially thought possible from this type of show.Unsurprisingly a great deal of character developments, in terms of personal growth, lies with the fallen angel. As the series progresses, she not only begin to show depth as a character, but at the same time get involved in a funny four-way romance. Various characters’ past have also been revealed which explains a lot about their current self, particularly their behavior. This also made them more real and believable as a whole.The sound department really deserves special recognition for this show. Not nothing does it have a special, one of a kind, ending per episode, but each ending also features the aftermath of what happened at the end of the episode (think of it as some form of epilogue). As an example, I strongly urge you to look up the second ending (flying pantsu ending). In addition to the various endings, the unique background music (BGM), that does not often repeat itself, also deserves honourable mention. Often times I feel that I was nearly going in tears thanks to these BGM. They make a strong compliment to the already excellent series.Sounds come in many different forms. Music obviously counts as one, but voicing is another, especially in the anime industry. Some voices can make a character seem like a lifeless zombie or can totally repel viewers from watching further. Others can bring life to a character, making them more lively and believable. Fortunately, Sora no Otoshimono has a large group of talented casts that helped make the characters come to life and also aided the comedy aspect of the show. If I were to select one seiyu from the group whom I believe have performed the best, it will have to be Souichirou Hoshi (Kira from Gundam SEED, Keiichi from Nigurashi no Naku Koro ni). His ultra hilarious performance as Tomoki, the protagonist, played a key role in the overall success of the series in my opinion. Though his voice may be hard to get used to at times, his role as Tomoki is certainly refreshing, highly different from most of his previous character voices.You may think that there is probably nothing else that is good about this series. You are dead wrong. The ultimate selling point of Sora no Otoshimono lies in the animation. While it does not have the unique animation techniques like those we often seen by SHAFT, this series cannot be taken lightly either. Production quality is top notch. With smooth fluid-like animation, great scene transitions, and consistently level of high quality production by the studio, all made this show an eye candy to watch. Of course this is especially true if you are into ecchi-fan service. But even if you are an action fan, you will not be disappointed as the series totally shines with its animation. You have to see it to believe it. Certainly one of the best quality anime (animation-wise) of the Fall 2009 season.To be honest, I am not an extremely big fan of ecchi comedy. But Sora no Otoshimono completely changed my view on this genre. I was really drawn in by the emotional scenes multiple times throughout the series. Similarly, I was also captivated by the very sad, yet powerful, scenes toward the end of the show. It certainly showed us that Sora no Otoshimono is not just about pure ecchi humour, but actually have a strong background story to back it up! I would also like to applaud the production studio, AIC A.S.T.A. for a job well done in adapting the original material from the manga. Lastly if you have read the entire review, do yourself a favour and watch the series now. It is only 13 episodes long, so why not give it a shot?
