In the year 2075, mankind has reached a point where journeying between Earth, the moon and the space stations is part of daily life. However, the progression of technology in space has also resulted in the problem of the space debris, which can cause excessive and even catastrophic damage to spacecrafts and equipment. This is the story of Technora's Debris Collecting section, its EVA worker, Hachirota "Hachimaki" Hoshino, and the newcomer to the group, Ai Tanabe.
This anime is realy great. I like the animation, would not mind to see more animes in this style. The characters are interesting and loveable. In the beginning it looks like there is no real story but in the end the first episodes are tied into the story in a realy nice way. Also it is a realy realistic Sci-fi, one could imagine that we can realy build every thing seen in the anime until 2073. I did not see anything "unphysical" as far as I can judge.
Even if you are not into Sci-fi I can recommend this anime. It is in a Sci-fi setting but has no tech-bubble or exotic technologie/aliens.
The end of the anime fits perfectly and let you think about humans, space and everything else.
