I remember reading this like a decade ago but didn't get the plot. The political/sociology undertones was too much to take in as a kid to make sense of, I guess. Back in the days I remember this traumatised me in more than one ways and gave it a 2, now I give it a 8 lul. Really cool how they portrayed the aftermaths of a war story while pursuing an identity quest. The best part about this manga is probably the depiction of the society the characters live it. Nailed the atmosphere. The number of chapters was little but damn the ride was jammed. I guess it's one of the series that you'll enjoy more the more series you read...
Now, I am happy that I finally understood it. Bittersweet story, made you wish more that could developed between these star-crossed lovers. I'm not totally satisfied, but felt that it was a fitting closure. My only critique was that the romance felt a bit too shoehorned in, especially with how fast things progressed in the end.
Really liked the arume's spaceship and designs. Wished the author would do more with these.
