I'm looking for a survival/ apocalyptic/ sci-fi (any interesting theme really) manga without an overpowered MC.

I don't want an MC that is "special" or "gifted". I don't mind if the character is strong if it's a muscular grownup - meaning it's believable, or someone who gets stronger throughout the story by experience and learning (e.g. Iwatobi from Green Worldz). The MC can be for example loyal/ smart/ cunning/ brave, persistent and that make tham strong. I'm just tired of seeing a high school boy/girl casually beating a gang of buff guys or someone who is the best at everything. I would like to see someone more human

Please recommend anything that comes to mind, the MC can be both male or female, thank you!!

I've not read that much (only like 20-30 chapters) of Tenkuu Shinpan but it looked like it might fit.

~4400 manga completed
~1700 ongoing...

I havent read it in a while but Hive seemed very realistic to me, the characters don't have any superpowers and just have to use their wits to get by

Kanata no Astra (Really wonderfully crafted sci-fi manga)
