The series didn't touch on VIRM's motives/goals so whatever reason they have for harvesting souls is up to anyone's guess. >_< Personally, I think souls aren't tangible entities, they transcend the physical, so I can't see them as energy source. Rather, like in horror shows, the souls are said to absorb energy from the environment to manifest in the physical realm, so er yeah, that's a different topic entirely haha.

Why would VIRM collect them then? Like you said VIRM is a cult, probably metaphor for religion and I think the VIRM planet is 'heaven' in this cult/religion. Those who subscribe to this religion are 'raptured' like the adults were, leaving the kids behind. The adults were probably implanted with a 'trigger' that kills them instantly when activated and their souls are harvested, because really, it doesn't make sense how the squads were able to keep their souls from getting harvested as well. One would think that VIRM would not leave a single soul behind if souls are really important to it, but even Hachi and Nana were spared, and they're implied to be 'immortals'.

So from this I'm guessing VIRM can only harvest souls from living beings who gave an implicit consent. i.e followed their teachings/doctrines. Though why not just gather everyone's souls when they're capable of harvesting it in the first place just don't make sense to me lol.

As for reincarnation, it was tacked on like a last minute idea so not really sure what to think of it. Perhaps those who haven't fallen for VIRM's doctrines do indeed reincarnate while those who followed the cult are raptured into the planet for whatever purposes. >.>

And so for the last point, it still boggles my mind to think that the adults were instantly raptured to the VIRM planet, while Hir02's souls took a thousand years to return. I'm not an expert in physics, but as souls, one would think the law of physics won't apply to them anymore, and yet, they traveled through space like physical entities. I mean, c'mon why not let them travel at the speed of light? haha

I'm not arguing, just thinking out loud lol

VIRM as a cult leader makes so much sense. :D
