Yeah maybe some of the mom's ants lie dormant in the Mc to protect him or it's an illusion not sure.
They also mentioned one of them survived and is in capture, that might be the mom (only the higher ups know) or Nr. 2 Kijima that actually escaped but they tried to hide that fact.
It would explain why only the page of the mom and son got ripped off from the book.
It would be interesting to see how the son came to live an ordinary life, he doesn't seem to be under surveillance except for Kijima's.
Maybe he was presumed a failure and Nr. 1 is the mom (who Kijima suspects to be with the son - plottwist).
That's all my wild theories for now
Hahahah I agree
Well now we know! Didn't expect him to be born with ants
Makes for an interesting backstory tho!
What I can deduct from this is that Mc, Kijima and red ant (which appeared in MC's mind when he almost gave up) was a family. And that they're the Ant-Castle Project subjects. The dad (Kijima) drunk on wanting to get more power after being an insector, wanted to consume his own family. Mom (Red Ant) fought with Kijima to protect MC and due to the fight, the lab exploded.
The "Case" that Kijima was looking for is MC. He is special and holds a tremendous power I think it's due to him being the No. 1 or very first test subject and is quiet young at that time . You know how on other stories goes about how special or I say, limited edition are the first subjects.
