Looking for anime but don't know the title?

I saw him on Netflix. It's about children who gain strength in their teens and who disappear again when they grow up. The forces come from a meteor that passes the earth once every 100 years. At the end of this anime, the main character robs all children of their strength so that nobody has to go to a laboratory.

Sounds like Charlotte. Haven't finished watching the anime though, so I'm not sure.

The anime is called Charlotte

Thanks
