This basically summed up my feelings about the manga.
I thought it was extremely great (I would have given it a 10/10) before the four-year time skip and Helena's death (which I seriously did not understand as to why she chose to go with that guy as opposed to Eliah).
I am never a fan of time-skips, I was able to accept the 20-year time-skip in the beginning, and it was indeed shocking to have found how the lives of our pseudo-protagonists had fallen apart.
The way the four-year time-skip was implemented however, gave me serious whiplash when I realized that a time-skip had occurred.
Eliah and Helena's rather sweet romantic relationship suddenly transitioned in Helena for some reason choosing to run away with a completely unintroduced stranger, and the two dying. There was no explanation for why Helena did this, either. Eliah's lack of emotional reaction was also very jarring, since he was so emotional in the first part of the story. As another poster said, the relationship was just so perfectly healthy that for it to be ruthlessly crushed through a weak time-skip left me feeling highly betrayed. I would have accepted if they drifted apart, but not through a weak plot device like a lazy time-skip. Obviously the author wanted a cheap shock factor, rather than develop out the relationship.
The pre-time-skip arc was also quite realistic. The initial virus's origin was plausible to an extent. The biology-related jargon (which I as a student enjoyed) helped hold up the setting as the path the world took 100 years from now.
It was with the Colloid, and the pseudo-science, and the sci-fi second half that ultimately ruined the story. It was unnecessary. I would have much rather wished that the manga had taken a route similar to the atmosphere and setting of the first half.
Overall, I had mixed feelings; unsatisfied feelings. I understand the importance of main character deaths in such a story such as this, but as the story wore on, it became apparent that the mangaka had overdone it. The killing of all the good character dynamics (Eliah/Helena, Keith/Sophia, Eliah/Mana, Enoa/Hana) left a empty husk in my enjoyment of the manga. The manga should have just focused just on the story of those characters rather than expand to extreme levels.
The story became empty, and I did not care nor got attached to any of the new characters introduced. This is a example of how too much killing of the lead characters also kills a story. By the end, there was no life left in the story. All the interesting and unique character dynamics were gone, and replaced with random new faces I couldn't care less about so far into such a long manga.
The first half had a unique and interesting premise. The second half was typical of a generic sci-fi novel and the overreach that kills many mediocre sci-fis.
First Half: 10/10
Second Half: 7/0
