Hypothesis here:
The large head/widely spaced eyes/small face seen in the anime here is known to be a pattern set into human brains, at the most basic level (often called our "reptilian brain"), to help protect children from grown humans.
This has been known for a long time (pics related). What if it's use here is not just to disrupt the hive mind? What if it's use is to ID the anons with the strongest protective instincts? Or, to open avenues to programming?
Who would have the most experience in, and motive for programming that part of our brain?
Reptilians?
