This is wrongly tagged as a transmigration novel. Here we have an OG native mc who is described as a genius and a friend of an important character. Just by this setting alone could change the plot severely. My biggest gripe in this is that the author failed to establish how the MC came into existence in this story, and that is making me feel disconnected with the story. Are we supposed to believe that the MC just came out of the blue without 'outside interference' or 'divine intervention'? Just treat this as a parallel world of Naruto and you're good to go. But for me, this is not it.
A very big problem with this story is that the readers have to believe that Konoha ninjas were easily overwhelmed by these zombies in the early chapters. And having no mc kinda sucks. Or maybe he was the one that was prophesied? LOL.
