The final episode of “Overlord” season 3 has been released, which signals the beginning of the waiting game for “Overlord” season 4. Based on several speculations online, fans will need a lot of patience as it might take as many as three years before the next anime installment is released.
It is also important to note that, at the moment, there is still no official announcement on whether or not Madhouse has ordered “Overlord” season 4. Fans can only hope that its current popularity is enough to convince the producer to continue the anime series.
To speculate when “Overlord” season 4 is coming, it is important to consider the state of the light novel series of the same title by Kugane Maruyama. It is the anime’s main resource material so it is safe to say that the development of the light novels is significant to the release of “Overlord” season 4.
OtakuKart argued that it could be tricky to open “Overlord” season 4 with volume 10 since the light novel and anime series follow a different timeline. Time jumps are easier to manage in the light novels but the anime series needed to be written differently and could pose some complications in the making of “Overlord” season 4.
The publication then considered the possibility that "Overlord" season 4 might not air until 2020. Other reports are open to the likelihood of the season having a 2021 premiere.
Meanwhile, fans have a different interpretation of the parting words shown in the last season 3 episode — “The Story Continues.” Some think that it simply means there will be an “Overlord” season 4 release. However, other fans joke that Madhouse could just be fishing for fans' support for the light novel to make more anime installments possible.
Aside from pondering when “Overlord” season 4 will come out, fans have also started speculating on the upcoming plot. The next installment is expected to continue the story based on the light novel's volumes 10, 11, and 12.
