In the year 2063, mankind's domain stretches across the vast expanse of the universe. Eight students from Caird High School, along with a young child, embark for an exciting interstellar camp on the planet MCPA, which is located nine light-years from their home. Among them are the brave and athletic Kanata Hoshijima and the cute and bubbly Aries Spring.

However, once the students arrive at MCPA, a strange ball of light starts chasing them. This mysterious sphere engulfs the students and sends them to a harrowing fate: a remote area of space located 5,012 light-years from safety. Hopelessly lost and quickly running out of resources, the students' only chance of returning home proves to be aboard a nearby abandoned spaceship, where their desperate fight for survival begins and the dark truths surrounding their deadly excursion are slowly revealed.

The story was great. Except, be warned. Around Volume 4, there are so many plot twists that you start to get kind of confused. But otherwise a really good manga.

Books 1-3 are pretty mild, they learn what happened, think about why they got "lost" in space, etc. But in Volume 4, they really start to discover stuff. Especially around the end of Volume 4 and the beginning of Volume 5, there is so much learned in such a short time that you might be confused. I would also recommend trying to read Volumes 4-5 right after each other to help with the confusion.

This Manga is not what it seems like. Its so much more!

Overall 10/10.
What i loved the most was the Type of Story Telling, which is very reminiscent of Manga Titles like Yakusoku no Neverland or Shingeki no Kyojin. What i mean by that is that the Story is told from the Perspective of Characters that have very limited knowledge about the Truth of the World, which hides Secrets that one would never have expected.

What seemed like a Space Slice of Life that raised a couple of seemingly unimportant Questions at the start, and continues to portray this image until halfway through the Manga with ...

I really don't know how this manga has so high reviews.
The only thing more difficult to know than the question before is where to begin with the problems of the series.

What if we make a history with ships that have limitless power? What if that alone make the whole plot stupid? Well, in this case we have Kanata no Astra.
This is by far the worst manga I'd ever read and I'm not kidding!
We have no consistent history, we have a new Deus Ex Machina at least per volume and NONE of those are explained
If the whole story isn't shit enough, we have this final, that ...
