Slime Season 4 Spoilers: Granville Rozzo vs Demon Lord Rimuru Fight Outcome and Full Breakdown

If there is one thing I love about That Time I Got Reincarnated as a Slime, it is the way the series can turn what looks like a simple political conflict into something much bigger. What starts as a struggle over trade, influence, and human-monster relations eventually becomes a battle involving ancient heroes, Demon Lords, hidden conspiracies, and powers capable of changing the entire world.

That is exactly why the Granville Rozzo vs Rimuru Tempest fight is such an important moment in Season 4.

On the surface, it looks like a straightforward confrontation between an ancient human warrior and the current Demon Lord of Jura. But there is much more happening behind the scenes. Granville is not simply trying to defeat Rimuru. His actions are connected to the Rosso family’s centuries-long plan, Mariabell’s ambitions, Yuuki’s betrayal, Chloe’s awakening, and the dangerous secrets surrounding Luminus Valentine.

And honestly, this is one of those Tensura battles where the context is almost more interesting than the punches themselves.

Why Granville Rozzo Hates Rimuru

To understand the confrontation, we need to look at Granville’s worldview.

For generations, the Rosso family quietly manipulated the Western Nations. Their influence extended into politics, economics, commerce, and the organizations responsible for protecting humanity. Granville, operating publicly as the Sun Luminary Gran, was one of the central figures behind this system.

What makes him interesting is that he wasn’t always motivated by simple greed.

Granville was once known as the Hero of Dawn, an ancient Chosen Hero who fought alongside the forces of Lubelius. After witnessing countless tragedies and eventually losing the person he loved, his understanding of humanity changed dramatically.

He reached a conclusion that sounds horrifying but makes sense from his perspective: humans were too weak to survive without someone controlling the world around them.

That belief eventually became the foundation of the Rosso family’s entire strategy.

The problem was that Rimuru completely destroyed the logic behind it.

Instead of forcing monsters away from humanity, Rimuru created a country where monsters and humans could cooperate. Tempest became prosperous, technologically advanced, and economically independent.

From Granville’s perspective, that wasn’t progress.

It was a direct threat to everything he had spent centuries building.

Mariabell’s Failure Changes Everything

Granville’s granddaughter Mariabell Rosso becomes one of the family’s most dangerous weapons against Rimuru.

Her approach is very different from Granville’s. Rather than immediately declaring war, Mariabell tries to defeat Tempest through economics and manipulation.

Her Unique Skill, Greed, allows her to exploit the desires of others, making her particularly dangerous in political situations.

But there was one enormous problem: she underestimated Rimuru.

Rimuru was no longer the inexperienced slime from the beginning of the story. With Raphael providing calculations and tactical support, Rimuru could analyze situations at a level that made many of Mariabell’s schemes almost impossible to maintain.

The confrontation eventually turns physical, and Mariabell’s plans collapse.

Then comes one of the biggest twists.

Yuuki Kagurazaka betrays Mariabell and kills her.

For Granville, this is the moment when the remaining pieces of his carefully constructed world begin falling apart.

His granddaughter is dead, the Rosso family’s influence is threatened, and Rimuru has become even more dangerous.

At that point, Granville stops playing the political game.

Granville’s Attack on Lubelius

Granville’s next move is far more aggressive.

While Rimuru is occupied with diplomatic efforts intended to improve relations between humans and monsters, Granville launches a coordinated attack against the Holy Empire Lubelius.

The objective isn’t simply military victory.

The chaos gives several other players the opportunity to move behind the scenes.

The battle quickly spreads across multiple locations, with powerful fighters entering the conflict.

Among them is Razul, whose arrival creates another serious threat. Rimuru’s forces, including Shion and Diablo, are forced to deal with the escalating situation while trying to protect civilians.

Meanwhile, Granville pushes through Lubelius’ defenses.

The Holy Apostles and Holy Knights struggle to stop him, and even Hinata Sakaguchi finds herself facing an opponent with an enormous amount of combat experience.

This is where the confrontation finally becomes unavoidable.

Rimuru arrives.

And the two finally stand against each other.

Granville Rozzo vs Rimuru Tempest

This is the part of the story I find especially interesting because it isn’t really a fight between good and evil.

It is a clash between two completely different philosophies.

Granville enters the battle with centuries of experience behind him. His abilities, holy powers, and Saint-level combat capabilities make him an extremely dangerous opponent.

But Rimuru has changed too.

With Raphael constantly analyzing the battlefield, Rimuru can predict and respond to attacks with incredible precision.

Granville also attempts to complicate the battle by using brainwashed Otherworlders as distractions. The goal is obvious: force Rimuru to divide his attention.

It doesn’t work as well as Granville hoped.

Rimuru is capable of coordinating his forces while keeping his attention on the main threat. Ranga and the other Tempest fighters can handle different parts of the battlefield, allowing Rimuru to concentrate on Granville.

And once the two actually exchange their strongest attacks, the difference becomes increasingly obvious.

Can Granville Actually Hurt Rimuru?

This is where the fight starts becoming less of a traditional battle and more of a demonstration of how powerful Rimuru has become.

Granville possesses devastating holy techniques and enormous experience, but Rimuru has defensive abilities that make conventional attacks extremely difficult to use against him.

His Universal Barrier, combined with the analytical capabilities of Raphael and the defensive potential of his Ultimate Skills, allows Rimuru to neutralize attacks that would destroy almost any normal opponent.

Granville realizes that overpowering Rimuru directly is becoming unrealistic.

And this is when the real plan begins to reveal itself.

Granville was never solely interested in killing Rimuru.

The Real Objective: Chloe’s Awakening

While the battle is taking place, another operation is unfolding.

Yuuki, Laplace, and Footman move toward the inner sanctum of Luminus’ territory. Their objective involves the mysterious Holy Ark and the dormant power connected to Chloe Aubert.

This completely changes the meaning of Granville’s confrontation with Rimuru.

The fight isn’t simply about revenge for Mariabell.

Granville is trying to create circumstances that will trigger the awakening of the legendary Hero.

That makes his final actions much more understandable.

He knows that he may not survive.

But if his sacrifice helps awaken Chloe’s true power, he believes that humanity will ultimately have a protector capable of facing threats far beyond ordinary human armies.

Granville vs Luminus: The Final Turning Point

Eventually, Granville’s path leads directly to Luminus Valentine.

Their confrontation carries enormous emotional weight because of their shared history and everything Granville has become over the centuries.

Granville’s obsession with protecting humanity has transformed into something oppressive. Luminus, meanwhile, represents a completely different understanding of what it means to protect her people.

Their battle pushes Luminus toward another major evolution.

She awakens the Ultimate Skill Asmodeus, King of Lust, giving her extraordinary authority over life and death.

At this point, Granville’s defeat is essentially inevitable.

But the ending isn’t portrayed as a simple villain getting what he deserves.

And personally, I think that’s what makes Granville’s conclusion work.

The Tragic End of the Hero of Dawn

Granville is eventually mortally defeated.

Yet, in his final moments, the hatred and obsession that consumed him begin to disappear.

He finally understands that his methods were wrong.

Humanity doesn’t necessarily need to be locked away behind an enormous political cage to survive. A changing world can create new possibilities that didn’t exist during his own era.

Rimuru is proof of that.

Chloe is another.

Granville ultimately accepts that the future belongs to a new generation.

His remaining heroic power and the Truth Sword are passed toward Chloe, symbolically bringing his story as the Hero of Dawn to an end.

It is a surprisingly emotional conclusion for a character who spends much of the story manipulating people from the shadows.

Who Wins Granville Rozzo vs Rimuru?

So, if you’re here specifically because you want the Granville Rozzo vs Rimuru outcome, the answer is straightforward:

Rimuru wins the confrontation.

However, saying that Rimuru simply destroys Granville and walks away would miss the point of the storyline.

Granville’s larger plan continues beyond the physical fight. His actions contribute to Chloe’s awakening, the collapse of the Rosso family’s influence, and the political restructuring of the Western Nations.

In other words, Rimuru wins the battle, but Granville’s final plan still has consequences.

That is a much more interesting outcome than a simple one-sided victory.

What Happens to the Rosso Family?

Granville’s defeat marks the beginning of the end for the Rosso family’s influence.

With Mariabell gone and the Five Elders defeated, the family’s grip over the Western Nations starts collapsing.

Tempest is suddenly in an even stronger position.

Rimuru has demonstrated that his nation isn’t simply another small kingdom. It has become one of the most powerful political, military, economic, and magical forces in the world.

The consequences are enormous:

• The Rosso family’s economic influence is shattered.
• Tempest’s international reputation grows dramatically.
• Lubelius and Tempest become much closer allies.
• Chloe’s importance to the future increases enormously.
• Yuuki’s betrayal becomes increasingly difficult to conceal.
• The story begins moving toward the coming Eastern Empire conflict.

And that last point is particularly important.

Tensura Season 4: The Rozzo Family Master Plan Against Rimuru Tempest Explained

Why This Fight Matters for Tensura’s Future

The Granville storyline isn’t an isolated side story.

It acts as a bridge between the political conflicts of the Western Nations and the much larger threats waiting on the horizon.

Rimuru emerges from the conflict stronger politically and personally. More importantly, he has proven that Tempest can survive against opponents who once seemed untouchable.

For me, that’s the real significance of this battle.

Early Tensura was largely about Rimuru discovering his abilities and building a home for the people around him. Later Tensura becomes much more ambitious. Rimuru isn’t just protecting his friends anymore.

He is becoming one of the people who determines the future of the entire world.

And Granville Rozzo vs Rimuru Tempest is one of the clearest moments where that transformation becomes impossible to ignore.

The former Hero of Dawn represents an old world built around fear, control, and isolation.

Rimuru represents something completely different: cooperation, technological progress, diplomacy, and the belief that humans and monsters don’t have to remain enemies forever.

That’s why I think this confrontation works so well.

Rimuru doesn’t simply defeat Granville’s body. He defeats the worldview that Granville spent centuries trying to preserve.

And with Chloe’s awakening, Yuuki’s increasingly dangerous plans, and the looming Eastern Empire War, the victory is anything but the end of the story.
