So far the book has been good. I like the development of the story, but I feel that not much has been introduced in the world background of what's going on besides trying to save the world. As in the goddess role aside from creation, or the god of destruction role behind the demon Lord's. I feel like it should introduce more of those aspects to explain their existence. My opinion of the storyline is that it is set good, but it's at a fast pace for the amount for chapters it has. For example his strange feats through his childhood aren't explained, besides the little introduction related to a selective memory skill. The book in it self has a good grasp of the style of OP MC. Overall it is a good book that's just starting.
