The details
Chapter 831 is adapted across anime episodes 791–792. The anime spreads this chapter across more than one episode, which is why the episode and chapter numbers drift further apart the longer the series runs.
One Pace re-cuts the anime to follow the manga's pacing, removing filler and padding. This chapter appears in Adventure in the Mysterious Forest.
