Man this story had a really strong start, but it really starts to slow down after the first 30 chapters or so, and as of chapter 85 I'm just kind of bored. The amount of mood whiplash in this story is really bizarre, a REALLY tragic thing just occurred, and then the next second they're just making jokes like it never happened. Not to mention the main characters are way too overpowered, the zombies stop being a threat really early on, and even other humans don't stand a chance against our heroes. It's also worth mentioning that there are some plot developments later on that are REALLY stupid, as in, it was so dumb I almost just stopped reading because of them.
Still, worth reading at least the first handful of chapters to see if you'll like it though.
