Trying to remember an anime I watched about 10+ years ago where in the backstreet theres a young girl screaming for her mother as she gets dragged away in an old fairy tale book. Something about them being non human and taken away by human men. I cant remember it for the life of me. I remembered it roughly 5 years back and meant to rewatch it but forgotten the name again since I believe this is somewhat of a flashback episode and the kid had been reawakened/summoned after some people have been experimented on
