I think the reaper either symbolizes that Zoro should've died, like any normal person would've in his situation, or Wano really does have actual non-symbolic reapers, but Zoro was able to resist it.
Wano damaged me beyond repair.
The pain wci caused might have only been cured by a banger Wano arc
But the banger Wano arc never came😭 the Wano we got instead was the fatal hit to my enthusiasm 😭😭💀
Yeah, the concepts of souls and ghosts in OP could use some clearing up. Why are BM's homies individuals with personalities, while Perona's ghosts are just sentient plastic bags that look the same? Brook calling up ghosts would be awesome- Oda should have him communicate with the dead once in a while.
