They might seem different but Arata naru Sekai: Mirai-hen and Coppelion both give off a similar vibe with a familiar environment. The main characters in fact hopes to prevent humanity's destruction in a futuristic settings. Additionally, the main characters all possesses special abilities that makes them more unique than others.
There is also the theme of science fiction along with emotional factors.
Both are about small groups of girls dressed in high school uniforms who are sent to an abandoned city (one is in the future and one was filled with toxic radiation). The girls wander around the city looking for clues. They have similar personalities with a level-headed leader, a childish and hungry girl, etc. They are both science fiction shows but Coppelion has action while Arata naru Sekai does not.
