That Time I Got Reincarnated as a Slime Season 4 May 1st Broadcast Cancelled: Unexpected Delay in Rimuru's Return

An unexpected development occurred today for fans of That Time I Got Reincarnated as a Slime (Tensei Shitara Slime Datta Ken). The broadcast of the series' highly anticipated 4th season, which was scheduled for May 1, 2026, has been removed from the official schedule. According to initial statements, this cancellation decision is due to unspecified "scheduling reasons." While it is not yet clear why the new season, which started with great fanfare at the beginning of April, is taking this short break, fans have already begun generating theories on social media.

This delay comes in the middle of the 4th season, the most ambitious season of the series to date. As you may recall, 8bit studio caused a stir in the anime world by announcing that this season would span 5 cours (approximately 60 episodes). The season, which premiered on April 3, 2026, covers the arcs where Rimuru Tempest and the Tempest Federation's political and military power reach their peak. Such disruptions in the broadcast schedule of such a massive production are often made to maintain animation quality or to avoid conflicts with special programming in the broadcast block.

Looking at the history of the series, the success of the light novels penned by Fuse has made the anime one of the top representatives of the modern isekai genre. Following the 3rd season, which ended in 2024, the series further solidified its popularity with the Tears of the Azure Sea movie, which was released last February. The story of Rimuru's transformation from a slime into a world leader has captivated millions of fans not only with its action but also with its deeply explored city-building and diplomacy elements.

So, what awaits us now? The cancellation of the May 1st broadcast likely means the series will take a short one-week break. However, a new broadcast schedule update from official channels will determine whether this break will be longer. While this news is a bit disappointing for us fans who want to watch the adventures of Rimuru, Veldora, and Benimaru without interruption, it is likely that 8bit studio made this decision to avoid compromising on quality standards. We will continue to follow the developments closely and keep you informed!
