Rating it 5/5 after reading Chapter 7
Writing quality must be the best thing in this story. I didn't catch any lapses, or it was barely noticeable. But the style itself is refreshing. The author didn't put too much info in a paragraph and it was just write.
Story development is zero to hero. After reading the MC got an ability and beat some fodder bully at the beginning, I would expect him to beat serious bad guy soon and instead of overpowering them, I would want to see him strategize more instead of overpowering them with given that he was the weakest.
Character's personality has a vengeful fury undertone. The unique skill could be an OP in the long run. The author could also run into some loops so I hope this skill could have some limitations, unless of course if this is actually included in the whole plot. (Given the synopsis is about god giving his powers to human, I get the impression god is getting those powers back through him. LOL)
World background, so far the ranking system is unique. Instead of Rank 1 being the strongest, the author did the opposite. The proper term would be Rating system. Like in chess, the higher your rating, the stronger you are. In this case, this is a good idea because it sets limitless possibilities in the appearance of stronger characters in the future. (Instead of the opposite where readers would usually look out for the top 10 ranks lol)
