While I do not want to ruin much of the plot, it is very good. Dicolonius are a what one would call a "evolved" form of human being that is cable of great feats. Not only do they possess great stamina they are able to use a power known as "Vectors" to manipulate the objects around them. These "vectors" are best described as arms that are able to grab onto things. Unlike normal arms, however, they extend very far (between 6-11 meters) and are capable of lifting heavy objects (like cars), or slicing through human flesh like salami. This is about as much as I can describe without spoiling too much.
The art is good but a bit dated. It is very graphic though, with much gore and nudity. If one could describe the goriness, think Hellsing OVA or Akira. The show could have done without so much nudity (the show is serious yet it is still trying to use fanservice...I appreciate it but too much saturation) but overall, the art is good.
The sound is amazing. The OP is sung in Latin and is reminiscent of a Gregorian Hymn (though it is a woman singing it). The OP alone is beautiful and I am glad that the show used the theme several times to emphasis certain plot points or events.
Most of the characters are likable but you may have already seen them in most other animes. The main character, Kouta, is the typical dude that is mostly normal but for some reason attracts women to him like moths to a light.
Yuka is his infatuated cousin who normally tries to get his attention every chance she gets. Nyuu is a seemingly innocent, pink haired girl that is very trusting and has a limited vocabulary. Nana and Mayu are two girls that are seemingly abandoned by their parental figures and are living a harsh life that no young girl should have to live.
In general, this description barely scratches the surface for these characters as each have their own, dark past and certain reasons for their motives. To reveal anymore would spoil everything so watch the show if you care to know more!
While the show is great, there are some parts that prevented this show from being a ten. One was the nudity. While I don't mind the nudity if it is for the sake of a scene (like a lab), the echii moments were unnecessary and distracted from the show at times. I also did not like how the show, as serious as it was, tried to disguise the fact that this show is a harem. (You know, lucky guy with a bunch of women in his place.)
This show is very dark though. It poses questions as to what is human and what is not. Is the death of an innocent being for the "greater good" really worth it? What of the ones who are guinea pigs, the ones who are "not" human yet are still capable of dreams, happiness, hope and love?
One being kills the other because it has the power to kill when in fact, both have the power to kill and destroy.
Overall, I really enjoyed watching the series. Episodes 5 and 13 were easily my favorites. It is a very moving series that will play with your emotions. My eyes watered in the last episode...for a series to do that to me is worthy of recognition.
While I recommend this anime, do keep in mind that it is not for everyone. I loved this series from start to finish, complete with an emotional roller coaster. For those not into this genre, it may not be for you and has disappointed its fair share of viewers.
Even so, this anime is amazing and an instant classic in my book. Watch it and decide for yourself. Just make sure to keep some tissue nearby just in case though!
