What One Pace is

One Pace is a fan project that re-edits the Toei anime to match the manga's pacing. It cuts filler, recaps, and stretched scenes, so a single One Pace episode usually covers the same ground as several broadcast episodes — here, chapters 869–870 re-cut from anime episodes 839, 840, 841, 885, 1156.
