Very good story, mc is overpowered but not in a way that makes it seem unbelievable as he doesn't just beat everyone like a lot of fanfiction. Story development is good there are a few twist and turns as well as original characters and story backgrounds to make the story interesting. Character design and development is pretty good the characters don't feel static they actually change and fee like real people. Although I wish he updated more stable and frequent, but the author does have a life so that may be unreasonable.
