Grayback
(Note for future new reader, if you want to be sure if the story are good or not, try to at least read to chapter 49 there and you will see how good the author writing are and the attention for the detail rather than plot hole, at least for the possible big plot hole anyway since the author lack writing experience early one. But it sure improve quick. For the problem of 'dialog too long/not as good' then I guess after around 30~35 chapter later it become better, and dialogues are concise from chapter 125ish onwards)
