It's a good read and it piqued my interest where I just binge half the chapters, but it suffers the fate as any other shounen story. The main character is likeable and shows how he will combat the tragic future in store. The problem is he's ignorant in that he doesn't think of whatever changes he does now will affect things differently in the future he knows. For example, changing the outcome of an event will create more events down the road that never occurred in the future he knows. I believe any common man would had thought of this and put it into their plan. The second, for such a battle-hardened experience fighter, he is quite naïve to believe that no one else has trump cards of their own and relies too much on his past-self ability and knowledge. Third and I believe the biggest problem with shounen in general is that villains are two-dimensional. Often times, they're portrayed as fanatics who in some cases even hurt their own cause. First major villain in the story was disappointing to say the least, wasn't expecting any surprises but c'mon, basically gave us the most cliché and stereotypical villain here. Another part is that the MC never manages to subdue or kill them outright, often times wanting to talk, believing they won without confirming it, or letting them escape so that they can go off and continue their mischief, guess you have to continue the plot somehow. Sorry for my rant, this is just my opinion so don't anything to heart. This doesn't mean I'll stop reading it but just annoyed how everything was going, this is still a good read.
