Salaryman Z has become one of my favorite zombie manga. I love the humor that comes with combining overly serious japanese work ethic and structure, with something as chaotic as zombie apocalypses while still having various tense moments, there are moments where the characters said work ethics are challenged in some way or different characters having contrasting ideas or methods and I think thats the most interesting part about reading this manga, seeing how they will eventualy overcome this. Salaryman Z is a very fun and original take on zombie apocalypses, if you like zombie apocalype stories with unique conflicts I recommend this one, It'sa very good read.
