Kiseijuu: Sei no Kakuritsu is about Parasytes that have invaded earth, whose main priority is to take over human bodies and use them as hosts, controlling their body and minds. Parasytes are fierce creatures who kill and feed on humans. The MC is a teenage boy name Shinichi whom one night is invading by a parasyte, but this attack somewhat fails as the parasyte named Migi, takes over his right hand rather than his consciousness. Thus allowing Shinichi to keep his humanity. They must work together to protect Shinichi's loved ones, and ultimately survive themselves against other parasytes.
The animation factor of Kiseijuu was done well throughout the 24 episodes. It did however vary between scenes, which by no means is due to lazy animators or time related issues, but rather is done to enhance the mood. For example, battle scenes as apposed to ordinary scenes simply had differences between them. Backgrounds and scenery had quite an amount of detail, and character designs hit the mark throughout the show.
The characters in this show are extremely well developed.
The companionship shown between Shinichi and Migi is fascinating in a way. They are both dependent on each other to survive. In the beginning it shows how they simply want to be free of each other, but their bond is so natural that it is difficult to pinpoint when the label of an annoyance is replaced by friendship. The background and emotional attachment each character has was done exceptionally well.
The soundtrack of Kiseijuu is quite possibly one of my favorites. There is a lot of diversity in this department, ranging everywhere from dub-step to instrumental. The OP and ED's suited the show perfectly. I usually have a habit of skipping the Openings with 99% of shows that i watch, however every episode i found myself pleasantly enjoying it. I couldn't find anything in this department of the show to fault. I was surprised with how honest the voice acting was. Not only the main characters, but the supporting were so convincing. It truly seems as though the creators designed the characters to suit the voice actors, not vise versa.
Prior to starting Kiseijuu, I had a preconceived idea of what it would entitle. A somewhat childish concept became a true work of art. It has been a pleasure finishing this anime for the past 24 weeks. It has the ability to appeal to such a wide audience. Whatever genre you prefer, i would advice you give this show a try as it has all the elements of a masterpiece.
