Contains the original broadcast version of episodes 1 to 8 and the "AfuReco" (アフレコ) version of episodes 1 to 3, which are unfinished versions used in the recording sessions. The "AfuReco" disc (ENFD_6006) is anamorphic unlike the letterboxed presentation on the other discs and the R2 PAL DVD.
As far as I'm aware, only episodes 1 to 9 and 11 were changed after original airing. The updated versions of episodes 1 to 9 [add bloom and color filters](https://slow.pics/c/B3QFI6i7). In episode 11 [they sadly fixed two of the funniest errors in the entire series](https://twitter.com/NLScavenger/status/1609895891229630467)
