All this zigzagging between a "fun" zombie apocalypse and human-focused drama is ruining this manga IMO. He really should just focus on the "fun" that a zombie apocalypse brings rather than turning into The Walking Dead! I hope it's not just me that hate human-drama in zombie series...
I don't really care for human villains in zombie series too, and holy shit, give the MC a little break, he just arrived after all! And I hope the village doesn't get ruined because of some pieces of shit since I'm interested how an isolated village like theirs might survive. How these NEETS survived and reached the village safely ahead of the other people in the tunnel to cause chaos is anybody's guess.
