I thought this manga was seinen and tried to read all 23 translated chapters, and got a big disappoinment. Though the first several chapters were quite okay, it became more and more stupid. Everything the main characters does is portrayed to be cool only, regardless of logic. I know that the ML wants to live a fun life and what not, but he acts like a high school boy. I can't believe this is labeled seinen, since apart from some facts and traumas about working in a black company, there's nothing else mature about it. If you want a carefree and fun manga about living in a zombie world, this manga is for you, but if you want some logic, grown-up content, this is not it.

It's a fun little satire about the adult working world, although the execution is pretty shonen (big expressions, themes of friendship and hard work, characters shouting out their competing world views while engaged in a battle of life and death)

The beginning was relatable and reminded me of Shaun of the Dead + Zombieland which is being a zombie-like worker in a society and enjoying the little things. It felt like it had somewhere to go but now I’m not sure. I’m also not digging the over the top expression...I mean it adds to the humor sure, but It felt overused to the point of exhaustion.

Wow this is actually an amazing series. One of the more unique and entertaining shounen series you will ever read. Great main cast, atypical characters but most of all, an absolutely atypical storytelling.

Highly recommended.
