On October 2nd 2018 the final Episode of Season 3 aired. But the buzz of a fourth Overlord Anime season has been rumored ever since that date. Today I'm taking a look into the odds, what we know about, and when you might see a Season 4 come out.
After the end of Season 3 Madhouse left a message at the end of the final episode of Overlord. They left a message at the end "and the story goes on" this can mean many things so I will go over them in detail. This can mean that Overlord is not getting any anime seasons and just advertising the Light Novels. This could mean that Madhouse has no plans to do another Overlord Season and another studio might take up animating Season 4. This happened when High School DXD had it's 4th season.
During the summer of 2019 Light Novel Author and Illustrator So-bin along with Anime Scriptwriter Yukie Sugawara attended a Anime convention in Germany. The German event falsely stated that a Season 4 was confirmed which it wasn't. It was alluded to. When the question came up about Season 4 Maruyama and So-bin had no comment while Sugawara took the mic and said that it was "extremely likely" that a Season 4 would come. Sugawara is a scriptwriter who has worked on Overlord, Sword Art Online, and Re:Creators so he may know something about it or could be lying which is unlikely given the job he has. But alas no confirmation was given or announcement made.
So when would a hypothetical Season 4 come out? Well the date is hard pinpoint due to the secrecy of the companies making anime and the studios. However, the date if using the amount of time that it took to get from Season 1 to 2 would estimate the arrival of Season being late this year, 2021, and the recent coronavirus outbreak has made 2022 be possible as well. So if you don't get a announcement tweet or trailer during those years then guess what Overlord is done.
Well I guess I'm done now if I missed anything let me know. Cya.
