Kurogane Communication

Both shows are about the interaction of human and robot in a post apocalyptic world. Kurogane is more lighthearted with comedy elements while planetarian is more serious. 

A small group of people wander around a barren world and have intimate and reflective moments together. 

Thirsty for post apacalypic stories where your a young sword dancer living in a dessert waste land where your being overunned by alien spider? or how about a story where young last surviving human girl wakes up from a cold sleep 30 years later in a futuristic city where her best friends are robots and androids which focuses on courage,survival and friendship? than Kurogane communication is for you if you liked The Third: the girl with the blue eye
