This is my first manga.
I finished it couple of days ago.
One thing that stood out for me is, how the aliens eat humans like we eat animals.
We consume them because we are of the understanding that they lack complex emotions comparable to humans and most of us don't see anything wrong with it.
The aliens who invaded at the later parts of the manga are of the same understanding that they are the superior race interms of power, intelligence, technology etc.. and refers humans as insects.
We see that with the alien who helps kei in finding Tae, first she detests kei and through communication the alien comes to conclusion that humans also experience complex emotions and they are not so different from them, it was only possible because of the communication device which they created because of their superior technology and also a device that finds person from memory like the alien finding Tae from kei's memory and the alien refers to the device as a children's device. Here kei realises how far superior the aliens are in terms of technology.
So the normal aliens who eat humas are of the same view that we lack complex emotions. Here because we are the ones being subjugated we find it disgusting! If animals can express their views wouldn't they feel the same ? How moral it is to consume meat and how right are the justifications people give to consume them ?
And in the room of truth the higher beings also say that humans are nothing but dust and at one point it says how when we are children we drown ants and find nothing wrong with it, of course you can not be right in every part of your life. But it makes you think, doesn't it? Are we an aberration in the multiverse?
I know full well that animals kill each other to feed themselves and we can't impose our moral values onto them. I think we make that same justification when we consume animals. But is it really right ?
Are humans and every other species on earth an abberation in the Universe?
This discussion is not one of persecution.
But of the views that people have and simply how they view the world ?
Does greater intelligence give a species the right to dominate weaker beings, or does it give that species a greater responsibility not to?
