Review Detail of KnightShade420 in DxD Dragon God

Honestly this did not feel like a story but a summary instead. I am generally a huge fan of Op characters but this story has the kind of Op character that I dislike. An Op character is only fun to read if there is progression. A storyline in which you basically decide to do time skips again and again in a single chapter is pretty lazy. A section just went 5 years later he mastered this, 10 years later he mastered this, 20 years later, 50 years later, blah blah blah. It was so boring.
