Alright, 2 things I got out of this chapter:
1. I feel like it's implied that Asura wasn't just one of a kind and that there are more beings like her. This might be tied to the "alien" theory Juuichi presented, just not literal.
2. Those children are NOT human at all. I've mentioned it in some other chapter, but literally everybody there is surprised that they discovered sex and could even get pregnant. Everything else seems to be pretty tightly written too, so I doubt the adults are just stupid. Seems like they don't consider all them kids to be humans neither.
Kids are probably half-Hiruko or half/quarter-alien (I mean whatever Asura was, I call them aliens just to have a word for it). And it seems like nothing like this has ever happened before, even though the facility have been running for at least 5 years (Asura killed herself 5 years before Tarao died).
There's something much more here than ignorance or negligence, I swear!
