Should I read the first gantz before reading this one?
no need
Thx
maybe not, but I'll highly recommend it :D
You’ll be happy if you did, but it’s not necessary. It is the same premise, just a different time period.
idk if this will give backstory too, so if you wanna know more about the origin/meaning of Gantz, read the other manga
