So the manga is set in a sci-fi and maybe post apocalyptic tone(I don't think I remember the world building) where humanity is getting attacked by monsters and humanity needed teenage girls to operate the mechs to fight these monsters and just when everything was going to shit and the pilot needed to self-destruct an anime character the pilot knew about popped out on a battleship and said what the hell are you people doing making girls/children fight(I don't remember but something along those lines) and that was about how the first chapter concluded IIRC. This has been bugging me for a couple of months now cuz I just remember this manga existing but can't continue it cuz I don't remember the name so halp PLS
