Every single character having no idea whats going on or purposefully not saying anything for 43 chapters straight is....writing for sure.
Why have any semblance of a story when characters can just aimlessly walk around and be mysterious I guess?
While you are at it might as well clone every character and wipe their memories(but not really).
The original had a similar problem but got a lot better towards the end.
This is just taking the piss.
