There’s a really disturbing manga that I remember reading in 2020, but for the love of all things, I can’t remember the title. However, I remember the story.
It’s about people who pilot these things that resemble human women, but are partially mechanical, kinda like Evangelion, but way more screwed up. It’s later revealed that the people piloting these things are actually tiny after a group of people from the present day wake up and encounter them, and then it ends with them pulling a plug to a giant computer.
