Are all the Initiators/Cursed Children 10 years old? Were there none born after that? In Black Bullet, the main Initiators are all 10 years old girls. But there are several taller and smaller girls shown in the background.

Are all the Cursed Children 10 years old, or are there others born after that?

Does the contamination of mothers through the mouth still happen?

Do the Light Novels explain this phenomena in more depth than the anime?



It seems to be several questions, but the point is the same. Just different phrasing.
According to the Black Bullet Wiki, the births of the Cursed Children are listed as a single year - 2021 - with Enju and Satomi pairing up in 2030.

So I guess the answer is yes, they're all 10 years old +/- 11 months.

The Initiator page also claims that they're all 10 year-old girls.
