The story boarding on these panels is atrocious. Take chapter 4 for instance: The MC is staring at some crystals, alone in the dungeon. On the very next page he's secretly tailing some mysterious cloaked figures, saying "Where did they come from?"
About 3-4 panels got lost in the sketching process. I say lost, but from the general pace of this series they probably never existed. The author just draws the highlights of each scene without the necessary visuals to connect them together.
