This is more recent and decent mecha series. For me it a 10! it may heve similarities with other mecha and sci-fi,but let's be honest>>all anime do. The point here is how they put it all together to form a story worth of your time! Sound: Metal riffs which might give off a starnge feeling at first but they give the series its caracter. I think its better than some balade that most anime have. Graphics: Graphics are 2D+3D mix which i love with more recent anime. In one word: superb! Story: The story is mature and for me it gives another perspective of human race and its behaviour.Are genetically inhanced humans the right way to go...perhaps :)

Plot:A huge shiny 500 kilometer in diameter ring-shaped structure had appeared near the Earth.
Five years later,from Markanan space station, several female astronauts wanted to investigate its nature. It leads to a fight with rebels on the ring itself and it triggers a massive energy blast which destroys the space station and causes huge destruction on the earths surface, after that it disappears.
A group of women and men with best genes and skills sets out to investigate the threat in a spaceship called Bilkis.

Bilkis is a ship retro engineered from knowlage humans got from ancient enhabitants of our galaksy:the giants. The ship has a colosal mecha attached on its underbelly whitch can be deployed. Its called the Shaft.
Shaft is powerfull enough to take out the rings but has unfinished OS and has bugs all the time.

Shaft is attracting the attention of mesterious rings and the force that controles them named Oberus. The race is on to find Oberus and destroy it before it destroys them.

The series is short. I wish it would have a few extra episodes to make the story more precise. But despite all unperfections this series grew on me quickly and its now on 5. place of my fav anime!
