by Fans of That Time I Got Reincarnated as a Slime (Tensei Shitara Slime Datta Ken, commonly known as TenSura) will have to wait a little longer for the next chapter of Rimuru Tempest’s journey. The anime’s Season 4 will not air this week, with Episode 89 postponed due to a special programming change on Nippon Television.
The delay is not related to production issues. Instead, the scheduled broadcast has been pushed back because the Friday Road Show movie “Jurassic World: Land of Resurrection” has an extended runtime, affecting the network’s programming schedule.
Along with the announcement, the production team has released the official synopsis, preview images, and broadcast schedule for Episode 89, titled “The Land of Convergence, Ruberios.”
Why Is ‘That Time I Got Reincarnated as a Slime’ Not Airing This Week?
The anime was originally expected to continue its weekly broadcast on Friday, July 31, 2026.
However, Nippon Television confirmed that the episode has been postponed because the preceding Friday Road Show special, “Jurassic World: Land of Resurrection,” occupies a longer-than-usual broadcast slot.
As a result:
- No new television episode will air this week.
- Simulcast streaming services will also skip this week’s release.
- Episode 89 will instead premiere the following Friday.
This type of schedule adjustment is relatively common in Japan, especially when major television events or special movie broadcasts extend beyond their usual time slots.
Episode 89: ‘The Land of Convergence, Ruberios’
The anime returns next week with Episode 89, titled:
“The Land of Convergence, Ruberios”
The upcoming episode promises significant developments involving several major characters and political factions as tensions continue to rise across the world.
Episode 89 Synopsis
The search for Chloe continues.
Determined to find her, Demon Lord Leon Cromwell requests assistance from Empress Elmesia of the Sorcerous Dynasty of Sarion before traveling to the Holy Empire of Ruberios.
However, Leon quickly discovers that the situation has already become increasingly dangerous.
The forces led by Granbell Rosso have begun preparations for a military assault, threatening to plunge Ruberios into large-scale conflict.
As multiple factions converge in one location, Episode 89 sets the stage for another major turning point in the series.
The Battle for Ruberios Begins
Ruberios has become one of the most strategically important locations in Season 4.
Several powerful individuals now have their own reasons for gathering there:
- Rimuru Tempest
- Demon Lord Leon
- Granbell Rosso
- The Holy Church
- Various political factions
With so many influential characters pursuing different goals, the balance of power appears ready to shift dramatically.
The episode title itself—“The Land of Convergence”—suggests that several storylines will finally intersect.
Leon Continues His Search for Chloe
One of the biggest ongoing mysteries of Season 4 revolves around Chloe.
Leon has searched for her for years, and his latest journey takes him directly into the center of the growing conflict.
His alliance with Elmesia, ruler of the magical nation of Sarion, demonstrates how important this search has become.
Fans can expect Leon’s storyline to receive significant attention in the upcoming episode.
Granbell Rosso’s Plans Continue
Meanwhile, Granbell Rosso, one of Season 4’s primary antagonists, continues moving his own forces into position.
A former Hero and leader of the influential Five Elders, Granbell believes humanity can only survive through strict control and domination.
His ideology places him directly at odds with Rimuru’s vision of peaceful coexistence between humans and monsters.
The conflict between these two philosophies has become one of the season’s central themes.
Season 4 Continues Expanding the World
Unlike earlier seasons that focused primarily on Tempest’s growth, Season 4 explores the wider political landscape of the world.
Current storylines involve:
- International diplomacy
- Religious conflict
- Military alliances
- Ancient heroes
- Demon Lords
- Kingdoms competing for influence
This broader scope continues to raise the stakes while introducing new allies and enemies.
The Story So Far
Following the successful Founding Festival, the Jura Tempest Federation has become one of the world’s fastest-growing nations.
Under Rimuru Tempest’s leadership, Tempest seeks to establish a society where:
- Humans
- Monsters
- Demons
- Other races
can coexist peacefully.
However, not everyone welcomes Rimuru’s vision.
Many influential leaders now see Tempest’s rapid expansion as a direct threat to the existing balance of power.
The Rosso Family’s Ambitions
Among Rimuru’s greatest opponents are:
- Granbell Rosso
- Mariabelle Rosso
The Rosso family believes humanity should maintain control over the world through authority and dominance.
Their growing conflict with Rimuru has become one of the driving forces behind the current season.
As political tensions rise, open warfare appears increasingly unavoidable.
A New Hero Is About to Awaken
Season 4 continues teasing the arrival of a mysterious new Hero.
The official synopsis suggests that multiple destinies are converging as:
- Heroes
- Demon Lords
- Nobles
- Religious leaders
all pursue their own ideals.
With unwavering determination, Rimuru prepares for another battle that could reshape the future of the world.
