What are production breaks for?
Why was I reincarnated as a slime back then, Season 4 went on hiatus
When a production hiatus occurs, it is often assumed that the production studio needed some more time to put together the next phase of the anime. In the case of Season 4, Episode 5 That time I was reincarnated as slimeit just happened that it was a public holiday. Golden Week is a series of public holidays that fall one after the other in the last week of April, run through May, and end on the 6th.
The reason it's a week is because of Japan's holiday laws, which require that every day between two holidays be converted into a holiday as well. Since four of these days are consecutive, many people take the entire week off. The week is “golden” as various industries experience a surge in revenue due to an influx of leisure customers.
The delay always happened
Golden Week takes place in the same week every year
Since Golden Week takes place at the same time every year, from April 29 to May 6, one would assume that the planners saw this and tried to find a solution. However, it could very well benefit this production. Season 4 slowly but steadily approaches the conflict between the Western nations and the Eastern Empire led by the Rozzo family of Seltrozzo. Since episode 5 has been delayed from its original May 1st premiere date, the production staff will be given some time to fill in and enjoy the freedom from the well-documented pressure cooker environment that anime production tends to be.
When is the time I was reincarnated as a returning slime?
The broadcast was originally intended for May 1st, now moved a week later
As already mentioned, Golden Week runs from April 29 to May 6 and its fifth episode That time I was reincarnated as slime Season 4 was originally scheduled for May 1, a week after the fourth episode. The new episode has been delayed by just one week and will be available to watch on Crunchyroll when it comes out on May 8th. Fans of the series were definitely excited to see the next episode of the series and were disappointed by the news of the delay, but as we understand it was always supposed to air later, due to the Golden Week break.
In the meantime, fans can catch up on Season 4 if they haven't already, or watch one of the OVAs or Scarlet weave movie currently available on Crunchyroll. It's also worth noting that we'll be getting a few follow-ups to Season 4 of That Time I Was Reincarnated as Slime, so the more rest production and everyone involved can get, the better!
