ohhh man,I was so excited for this manga,it's the only manga that I read about 60+ chapters of in one day,it started really great with the thriller and mystery storytelling,then continued to be really great in almost all aspects,then it began to unfortunately plummet to a rushed storytelling. I liked the art -but not all the time- ,the story was what grabbed me to read it,it was really great,and then I found myself waiting every week to read every new chapter just for the sake of reading them,not for how good the chapters were.
about the characters,at first they were helpless shounen protagonists,then became unstoppable with the magic of plot armor,every plot twist we had in mind was averted,everything in the story seemed like it was on a straight line.
so,we put the protagonists in a really dangerous situation,don't worry no matter what happens they will make it.
(spoilers) about the ending,for what it is,for me it's good,but not that good,if the series continued with the great storytelling it had from the beginning,the ending would've been much much better,but regarding what happened to the story,this ending is fitting.
I just hoped that they had enough time to resolve some unresolved mysteries.
overall:it's not that bad,but unfortunately it went downill,I give it a 7 out of 10.
