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 863–864 re-cut from anime episodes 833, 834, 885.
