The original Season 1 of A Record of a Mortal's Journey to Immortality (2020) and the Season 1 Remake (often called the Remastered Edition, 2023) tell the same core story, but the remake heavily upgrades the series' 3D animation. The original Season 1 runs around 21 episodes, which the remake condensed into a smoother, 21-episode run with altered pacing and visual polishes.
