I feel like this part of the manga looses punch in absence of the connection you're already supposed to have with the characters. Also, I feel like starting here gives it more of a generic post apocalyptic feel as a first impression. Of course we know that is not the case but honestly, I might have dropped it if I didn't know the source material. Still, I don't want to hate too soon so I'll give it time haha. Still excited that Asano finally got adapted.
