Manga name

[Niewaznekto]

I forgot the manga name: It followed a group of girls, (starting high school?) one was chubby and mother-like, one was tall with father complex, and i think there was 1-2 more? Set in rural japan after a cataclysm which destroyed major cities? There was a mascot character, and i seem to remember them fighting some kind of aliens? But it had this fluffy feeling.
