Demon Slayer’s Muzan Is Not the Villain Who Broke Tanjiro the Most

by

Muzan Kibutsuji is responsible for the tragedy in Tanjiro’s life. He killed Tanjiro’s family and turned his sister, Nezuko, into a demon, setting Tanjiro on a path of sorrow and constant fighting. Without Muzan’s actions, Tanjiro wouldn’t have become a Demon Slayer, and Nezuko wouldn’t need his protection from both demons and people. However, the story makes Tanjiro’s pain even deeper by portraying Muzan not as a constant, direct threat, but as a shadowy, distant evil that looms over everything.

Just when things seemed to calm down after the fight on the Mugen Train, Akaza appears and brutally kills Kyojuro Rengoku before Tanjiro’s eyes. This devastating loss completely shatters Tanjiro, leaving him unable to find any meaning in the tragedy. He’s powerless to save Rengoku, defeat Akaza, or even force the demon to face the consequences of his actions. All he can do is helplessly shout after Akaza as he escapes.

Muzan Creates Tanjiro’s Pain, but Akaza Makes Him Feel Helpless

Before the story even starts, Muzan ruins Tanjiro’s life. This devastating event becomes the driving force behind everything Tanjiro does. He loses his mother and siblings, and his sister, Nezuko, is turned into a demon – all because of Muzan. Though filled with grief, Tanjiro finds a new purpose: to protect Nezuko and find a way to restore her humanity.

The pain Tanjiro feels is overwhelming, but it fuels his journey and gives him a purpose, even though his sadness never fully disappears. Akaza’s actions are particularly devastating because Tanjiro witnesses the tragedy firsthand and can’t do anything to stop it. He observes Rengoku’s battle, realizing the huge difference in power between the Hashira and the Upper Ranks. He sees Rengoku fight bravely, but ultimately watches Akaza live on, retreating into the forest.

That feeling of powerlessness is significant. Tanjiro is accustomed to hardship and usually overcomes it with determination, but against Akaza, simply trying harder isn’t enough. His bravery and kind heart can’t help him because the person he’s trying to save is already too far gone. While Muzan’s attack gives Tanjiro something to strive for, Akaza’s attack forces him to confront the painful reality that wanting to protect someone doesn’t guarantee their safety.

Rengoku’s Death Hurts Because He Makes Tanjiro Believe in Safety Again

Rengoku’s importance goes beyond just a single task; he embodies the strength Tanjiro strives to achieve. He doesn’t see Tanjiro, Zenitsu, and Inosuke as liabilities, but instead mentors and safeguards them, demonstrating the qualities of a true Hashira. This makes Akaza’s appearance especially heartbreaking, as Tanjiro and his friends have already overcome a terrifying ordeal that could have been fatal, and a lower-level demon has already been defeated.

The fight offers a brief respite, and Rengoku proves why he’s a Hashira. But Akaza’s sudden appearance completely shifts the mood, reminding Tanjiro that even winning a battle doesn’t mean true safety. Just because they defeated one demon, and are fighting alongside a powerful Demon Slayer, doesn’t guarantee victory or protection. Akaza shatters the sense of comfort Rengoku built, making this moment particularly painful.

Rengoku’s death is particularly painful because Tanjiro looked up to him so much. Although they didn’t have a long history like childhood friends or family, Rengoku quickly became important to Tanjiro by demonstrating that great strength doesn’t have to mean being unkind. Rengoku was powerful yet compassionate, and confident without being arrogant. When Akaza killed him, Tanjiro lost someone who had just given him a glimpse of the person he aspired to become.

Tanjiro’s Anger at Akaza Comes From Shame as Much as Grief

Tanjiro’s outburst after Akaza flees is one of the most emotionally powerful scenes in Demon Slayer. He calls Akaza a coward for avoiding the sunlight, which is technically correct – Akaza can only survive by running from it. But Tanjiro’s anger stems from a deeper sense of shame. He’s frustrated with his own inability to defeat Akaza and desperately tries to express his sorrow as condemnation, as he feels he has nothing else to offer in that moment.

The tragedy of the scene stems from Tanjiro’s helplessness against Akaza and his inability to save Rengoku. Though Tanjiro understands Akaza’s flawed logic and recognizes Rengoku’s greater skill and the value of human life, those truths aren’t enough to change the outcome. Akaza highlights the gap between Tanjiro’s strong beliefs and his current power. It’s a painful reminder that even when someone is morally right, they can still suffer a devastating loss.

Even when Tanjiro desperately wants things to be fair, he can still be forced to watch a villain get away. This is especially painful because it challenges what he fundamentally believes – that kindness and hard work are important, and that protecting people is always worth the sacrifice. Akaza doesn’t disprove these beliefs, but he shows Tanjiro that they need to be backed by strength. Tanjiro is left haunted not only by Rengoku’s final words, but also by the crushing feeling of not being strong enough to save him.

Akaza Becomes the Villain Tanjiro Has to Outgrow Emotionally

Akaza embodies a strength Tanjiro hadn’t yet achieved during their fight, and that defeat continues to motivate him. Tanjiro is determined to grow powerful enough to prevent another tragedy like Rengoku’s, making his rivalry with Akaza surprisingly more personal than with Muzan himself. However, the sheer scale of Akaza’s power feels distant and overwhelming for much of Tanjiro’s development.

Akaza represents the ultimate tragedy. Tanjiro vividly remembers the battle with him – the sounds, Rengoku’s unwavering stance, the dawn breaking, and the demon fleeing after causing an irreplaceable loss. Akaza also questions what it means to be strong. He believes human frailty is something to be avoided at all costs, and desperately wants Rengoku to become a demon because he can’t understand why someone powerful would choose to live a mortal life.

Rengoku doesn’t give in to power-ups because his strength comes from protecting people even while acknowledging his own limitations. Tanjiro learns this lesson through his sorrow. This is why defeating Akaza is so impactful later on – Tanjiro isn’t just seeking revenge for Rengoku, he’s fighting to prove that Rengoku’s values were meaningful. While Muzan is Tanjiro’s biggest enemy overall, Akaza is the one who shows him the pain of losing someone he admires.
