A captivating manga with plenty of action and comedy. Bored gods, who have turned the world into chaos with monsters, grant powers to some people. A classic theme. I've read another manga by the same mangaka, and that one was also good. The main character's thirst for revenge drives him to continue striving even when he lacks power, and he never forgets his original goal when he gains power... I really liked the main character's determined attitude. Of course, we shouldn't forget the cute characters who accompanied him.They even added a romance element. However, even though the main character got his revenge in the final episode,everything was cut short there. Many things were left unexplained.Is the main character compatible with that core or not? Did he marry the girl that readers will know about, and I wish we could have seen it. The gods, out of boredom, brought the world to this state, but what exactly is the cause and what's the solution to end it? At least they could have answered whether monsters would always roam the world. Also, it was the metallic, gray-colored Null-Blade that destroyed the main character's home and family. It's not exactly revenge; I think the main character would have gotten his full revenge if he killed all the Null-Blades, especially that particular one. All the things I was curious about could have been turned into at least 30-50 more chapters. They wasted a good manga, a story that had potential to be developed, by canceling it.If they hadn't ruined this manga with such a shortened ending, it would have received at least an 8 point from me.
