Something like 7 Seeds.
Post apocalyptic and people aren't trying to kill each other.
Focused more on surviving and trying to rebuild.
Any genre.

Please and thanks.

Where it says something like 7 Seeds, that mainly applies to the mentioned points.

More focused on helping others/have survival techniques & advice/turn on each other/try to rebuild their lives or start new ones:
Jisatsutou
Meteor
51 ways to save her (rape warning)
The drifting classroom
Cage of eden
Area D - Inou Ryouiki
Coppelion
Eden - It's an Endless World!
Juuousei
Kisswood (but rebuilding is a pretty different plot)
Malicious code (or seems to be from what iv read)
Sprite

Kill each other/help each other/conserve for the foreseeable future:
:Reversal
Apocalypse no toride
Highschool of the dead
Kaguya hime (putting it here cos i can't remember the plot well, but has similar atmosphere to 7 seeds)
Aphorism
Shingeki no kyojin

Battle Royale
Btooom!

Both have a lot of violence though.

Thanks for these, but I do want to emphasize the post apocalyptic and working together to survive and rebuild.

Ah...oops, missed the post-apocalyptic.

The best one I can think of is The drifting classroom, its post apocalyptic, similar plot with kids dropped into the future and having to deal with strange new features of this future world. They work together at points, becomes lord of the flies at points and they work to rebuild the future and survive. Aldo a few adults like in 7 seeds.

Cage of eden is also the sort of thing you want. Post apocalyptic, kids and a few adults dropped into this strange world. Strange creatures like in 7 seeds (there its new species, in this its extinct species,) have to work together to avoid them/take them down. They form a large group and make houses and the such. Plus there's factions and murders and stuff too.

Plus I know it isn't strictly post-apocalyptic, but Jisatsutou has a lot of working together to survive, its informative, has a similar system of communities and they use old things left on the island and use it to rebuild.

Sprite has a lot of working together, its post apocalyptic and theres a community type feel. Strange monsters like 7 seeds, have other factions of people to contend with and centers around students, like in 7 seeds. They don't aim to rebuild the world, just fortify their home.

Meteor is post apocalyptic but not as strong as the other titles. Shingeki no kyojin is more like a city that rebuilds. 51 ways to save her isn't post apocalyptic, just a disaster in tokyo but they do cooperate to survive quite a bit. Jyu-oh-sei is also more like a fully fledged world with already realized communities and towns, its also more a wild planet than post-apocalyptic, but it has the same nature has taken over feel.

I read Cage of Eden, its not really post apocalyptic, especially with that ending. 😕
Thank you for the other ones, I'll give them a go.

The Drifting Classroom is the closest to what I wanted. Thanks.

More please.

Apocalypse no Toride if zombie apocalypse is okay with you.
It's more about trying to survive than to rebuild though... But it seems much more interesting than your generic zombie plot, it has a tinge of mystery to it and all the characters are unique and interesting.

It does sound interesting, so I'll read it. However, I am looking more for the rebuilding aspect.
Thank you.

I love survival and post-apocalyptic manga.
I'm thinking Bio Meat (monsters?) and I am a Hero (zombies), but these lack the "rebuilding" aspect.
Dragon Head leans a bit more in that direction.
None of these are as close to 7 Seeds as Drifting Classroom, though.

I'll read Bio Meat and Dragon Head.
But I'm still looking for something that better fits what I'm looking for.
