That Time I Got Reincarnated as a Slime Season 4 Episode 19 Release Date, Time, and Streaming Guide for the US
There are plenty of isekai protagonists who become ridiculously powerful after being reincarnated, but very few have turned that power into something as absurdly large as Rimuru Tempest. What started as the story of a salaryman reborn as a blue slime has gradually become a sprawling saga about kingdoms, demons, diplomacy, war, and the future of an entire world.
That is exactly why I have been keeping such a close eye on That Time I Got Reincarnated as a Slime Season 4. The scale of this season is honestly hard to wrap your head around. Instead of another short 12- or 24-episode run, the anime is being handled as a massive multi-cour project, giving Rimuru and Tempest far more room to breathe.
And now we are approaching Episode 19.
If you’re watching from the United States and want to know when you can actually sit down and watch the next episode, here’s everything you need to know about the That Time I Got Reincarnated as a Slime Season 4 Episode 19 release date, US release time, streaming platform, and story expectations.
When Does Slime Season 4 Episode 19 Release?
That Time I Got Reincarnated as a Slime Season 4 Episode 19 is scheduled to release on Friday, August 14, 2026.
The fourth season began its current broadcast run on April 3, 2026, and the ongoing schedule has allowed the story to move forward at a much faster pace than some previous seasons.
For me, that’s one of the most exciting things about this season. TenSura has always had a ridiculous amount of world-building to work with, but sometimes the anime has spent so long explaining politics and meetings that the action felt like it was waiting in the next room.
The larger Season 4 format changes that feeling.
Episode 19 arrives during the second cour, with the story continuing its steady weekly progression through the summer.
Episode 19 Release Details
| Detail | Information |
|---|---|
| Anime | That Time I Got Reincarnated as a Slime |
| Season | Season 4 |
| Episode | Episode 19 |
| Release Date | Friday, August 14, 2026 |
| US Streaming Service | Crunchyroll |
| Subtitles | English subtitles |
| Current Format | Multi-cour Season 4 |
There have been scheduling changes during the season, including a recap broadcast in Japan, but the overall release pattern has returned to its regular rhythm.
So, unless another official scheduling announcement changes things, August 14 is the date US viewers should have marked on their calendars.
What Time Does Slime Season 4 Episode 19 Come Out in the US?
This is where things get a little confusing for American viewers.
The episode is released internationally alongside the Japanese broadcast schedule, but the exact clock time naturally changes depending on where you live in the United States.
The current Crunchyroll schedule puts the English-subtitled episode at 8:00 AM Pacific Time.
Here’s how that translates across the country:
- 8:00 AM PT — Los Angeles, Seattle
- 9:00 AM MT — Denver, Salt Lake City
- 10:00 AM CT — Chicago, Houston
- 11:00 AM ET — New York, Miami
So, if you’re an East Coast viewer like me, there’s no need to stay awake until midnight for this one. Episode 19 should arrive at 11:00 AM Eastern Time on Friday, August 14.
That’s actually a pretty convenient release time. You can get through the morning, grab lunch, and then check what Rimuru has been up to before the day gets too far along.
As always, streaming schedules can occasionally be adjusted, so it is worth checking the episode page on release day if the episode doesn’t appear immediately.
Where Can You Watch That Time I Got Reincarnated as a Slime Season 4 Episode 19?
For viewers in the United States, Crunchyroll is the main destination for Season 4.
That makes things relatively simple. You don’t need to hunt through half a dozen services trying to figure out where the newest episode has gone.
The current setup is essentially:
Crunchyroll → Season 4 → Episode 19
A premium subscription is generally required for access to newly released episodes during the initial release window.
Other streaming services may carry TenSura in different territories or receive episodes later, but availability varies heavily by region. For American viewers who want to follow the weekly release as it happens, Crunchyroll is the service to keep an eye on.
Why Season 4 Feels So Different
The biggest thing that stands out about Season 4 isn’t necessarily one specific character or battle.
It’s the scale.
This season is being treated as a huge multi-cour production, with five cours planned across the larger Season 4 project. In practical terms, that gives the anime considerably more space to handle Fuse’s world-building.
A single cour normally covers three months of television programming and often contains around 11 to 13 episodes. TenSura is going far beyond that conventional structure.
And honestly, I think that’s exactly what this series needs.
Rimuru’s world has become too complicated for the anime to constantly rush from one major event to another. There are nations to manage, alliances to establish, monsters to control, demons to negotiate with, and enemies who are becoming increasingly difficult to ignore.
The longer format gives those elements room to actually matter.
The Current Season 4 Structure
The broad plan can be thought of like this:
- Cour 1: Spring 2026
- Cour 2: Summer 2026
- Remaining Cours: Later portions of the larger Season 4 project
That means Episode 19 isn’t some isolated milestone. It is part of a much bigger storyline that is still building toward considerably larger conflicts.
What Could Happen in Episode 19?
This is where I would be careful about going too far into spoiler territory.
By this point in the story, Tempest is no longer a small monster nation trying to prove that it deserves a place on the world stage. Rimuru has created a power that other nations simply cannot ignore.
And that’s a problem.
The Western Nations have their own interests. The Eastern Empire represents an enormous potential threat. Tempest’s growing economic influence creates another layer of tension, while Rimuru’s increasingly powerful subordinates make the entire federation look even more intimidating from the outside.
Then there is the Labyrinth.
What I particularly enjoy about the Labyrinth storyline is that it isn’t simply treated as another dungeon where characters run in, fight monsters, and collect treasure. In Tempest, it becomes a strategic asset. It has economic value, military value, and political value.
That is classic TenSura.
Rimuru doesn’t just ask, “Can we defeat this enemy?”
He asks, “How can we turn this situation into something that benefits Tempest?”
That mindset is one of the main reasons I still find the series so entertaining after all these seasons.
The Eastern Empire Problem Is Getting Harder to Ignore
The biggest shadow hanging over the wider story remains the Eastern Empire.
Even when the immediate episode isn’t focused entirely on the Empire, its presence influences the decisions being made throughout the world. Tempest has grown powerful enough that a confrontation eventually feels less like a possibility and more like something everyone is preparing for.
And then you have Rimuru’s Primordial Demons.
Whenever characters like these start becoming more active, I immediately start wondering how far the anime is willing to go. They are not ordinary soldiers, and their loyalty to Rimuru makes them incredibly dangerous opponents.
Episode 19 should continue moving the pieces around the board.
Whether it delivers a huge battle or focuses more heavily on political developments, the important thing is that the larger conflict is becoming increasingly difficult to avoid.
Will Episode 19 Be Mostly Action?
If you’ve watched TenSura for any length of time, you already know the answer is probably going to be: a little of both.
One of the things that makes this anime different from straightforward action is its willingness to spend time on conversations, negotiations, planning sessions, and nation-building.
Some fans absolutely love that.
Others have spent years joking about Rimuru sitting in another meeting while everyone else waits for the next fight.
Personally, I think the balance works best when the political material eventually leads somewhere. Give me the meetings, the negotiations, and the strategy discussions — just make them pay off later.
Season 4 has enough material and enough runtime to potentially achieve that balance better than previous seasons.
My Expectations for Episode 19
I’m not expecting Episode 19 to answer every major question surrounding Tempest. If anything, I think the episode’s biggest job is to keep the larger machine moving.
The pieces are already in place:
- Tempest is becoming a dominant global power.
- The Western Nations are watching Rimuru carefully.
- The Eastern Empire remains a looming threat.
- The Labyrinth continues to have strategic importance.
- Rimuru’s strongest followers are becoming increasingly important.
That’s a lot of pressure for one slime.
And that’s precisely why I’m looking forward to this episode.
TenSura works best when Rimuru’s ridiculous power isn’t the only thing driving the story. The fun comes from watching him build something that other characters initially consider impossible, then watching those same characters realize just how far Tempest has come.

Final Thoughts
That Time I Got Reincarnated as a Slime Season 4 Episode 19 arrives at an interesting point for the series.
TenSura has moved far beyond its original premise. Rimuru isn’t simply trying to survive in a fantasy world anymore. He is running a nation, negotiating with powerful civilizations, commanding monsters and demons, and preparing for conflicts that could affect the entire world.
That’s why I find the current season so interesting.
The biggest question isn’t really whether Rimuru can win his next fight. At this point, that’s often the easy part.
The more interesting question is what kind of world Rimuru is going to create with all that power.
Episode 19 should continue pushing that idea forward, while bringing us another step closer to the much larger conflicts waiting later in Season 4.
For US fans, the important date is Friday, August 14, 2026, with the episode expected to arrive on Crunchyroll at 8:00 AM PT / 11:00 AM ET.
So yes, the slime is back.
And considering how enormous this season has become, I have a feeling we’re nowhere near the end of Rimuru’s biggest problems yet.
