Lead-Up to the Final Battle
After the chaos of the Infinity Castle arc, Muzan escapes to the surface. Severely injured but still deadly, he prepares for one last massacre. The Demon Slayer Corps, battered and bloodied, regroups for a final stand under the looming threat of dawn. Many Hashira suffer grave injuries; some will not survive this final encounter. Notably, Mitsuri Kanroji and Muichiro Tokito sustain fatal wounds, their sacrifices etched into the Corps’ legacy.
Tanjiro vs Muzan: Battle Timeline Breakdown
Muzan, in his true monstrous form, possesses rapid regeneration, shapeshifting tendrils, and devastating speed. For instance, his tendrils allow him to attack from all angles, forcing the Hashira into constant defense. Tanjiro, already exhausted, is quickly mutilated—losing his eye and eventually his arm.
Despite Muzan’s dominance, coordinated tactics and relentless attacks slowly wear him down:
- Giyu Tomioka lands a crucial blow using Water Breathing, momentarily staggering Muzan.
- Sanemi Shinazugawa distracts Muzan with his ferocity, creating vital openings.
- Obanai Iguro fights valiantly while severely injured, his unwavering dedication and fierce attacks helping protect his comrades and buying Tanjiro crucial moments to press on.
As the sun begins to rise, Muzan’s regenerative powers weaken. Dawn becomes their greatest weapon in the Muzan vs Tanjiro climax.
Muzan’s Final Move: Turning Tanjiro Into a Demon
Cornered by the sun, Muzan makes his last gamble. With his dying breath, he injects Tanjiro with his blood and consciousness. Muzan believes that through Tanjiro, he can achieve what he never could—becoming a demon immune to sunlight.
But this act is more than just survival—it’s a cruel twist of fate, a mockery of the Demon Slayer Corps’ efforts, and a desperate attempt to prove his superiority by turning their greatest warrior against them.
Demon King Tanjiro: Power Levels & Abilities
Now a demon, Tanjiro becomes Demon King Tanjiro, awakening with power surpassing Muzan. He is immune to sunlight, possesses absurd regenerative speed, and a berserker’s strength. However, unlike Muzan, Tanjiro’s soul fights back.
Sun Breathing’s divine link becomes critical here—it’s not only the original breathing style but also the antithesis to Muzan. Its connection to Yoriichi Tsugikuni and divine origins terrify Muzan, as it represents the ultimate force against demons.
The Ending Explained: Tanjiro’s Return to Humanity
Despite the horror of what he became, Tanjiro resists. Thanks to the efforts of Nezuko and Kanao, he is purified and returns to human form.
- Nezuko, now human, reaches Tanjiro through emotional resonance and her unique blood, once used in demon transformation research. Her humanity and love act as a tether for Tanjiro’s fading will.
- Kanao uses the Flower Breathing: Equinoctial Vermilion Eye, enabling her to inject the serum in a final act of self-sacrifice and timing, though it comes at a grave cost to her own vision.
This isn’t just a victory over Muzan. It’s a triumph of will, love, and the central theme: that humanity, no matter how fragile, can overcome darkness.
Fan Theories & What-If Scenarios
- What if Tanjiro stayed a demon? The world would face a new, nearly unstoppable tyrant. Given his innate talent and immunity to the sun, Demon King Tanjiro would have presented an unprecedented threat.
- Was Nezuko the true key? Her transformation suggests a natural cure for demonhood, shaking the very foundation of Muzan’s ideology. Some believe her bloodline holds divine origins.
- Sun Breathing’s divine link: The idea that Tanjiro’s breath style was fate’s counter to Muzan has led to theories that Yoriichi’s spirit was guiding him all along.
Community Takes: Reddit + YouTube Analysis
- Reddit: Fans debated whether Muzan was truly unbeatable or just overhyped, with some arguing his overwhelming power against the full Corps proved his might, while others noted the collective effort eventually brought him down.
- YouTube: AMVs like “Tanjiro vs Muzan: Final Stand” and deep-dives by creators like Zhoniin or Manga Mind received millions of views, often highlighting the emotional crescendo of the battle.
- Quora: Mixed takes—some say Tanjiro surpassed Muzan, others believe it took the entire Corps to even stand a chance.
FAQ-Tanjiro vs Muzan
Is Tanjiro stronger than Muzan?
Not initially. Throughout the battle, Muzan remains physically stronger, faster, and more durable due to his overwhelming demonic powers and centuries of experience. However, in the final moments, Tanjiro’s strength comes from more than just power—it’s his resilience, Sun Breathing mastery, and unbreakable will that push him beyond his limits. When Muzan turns Tanjiro into a demon, Demon King Tanjiro briefly becomes even more powerful than Muzan, possessing immunity to sunlight and superior regeneration. But as a human, Tanjiro never outright overpowers Muzan—he wins with help, strategy, and heart.
How does Tanjiro defeat Muzan?
Tanjiro doesn’t defeat Muzan alone. The victory is the result of a massive coordinated effort by the entire Demon Slayer Corps and the surviving Hashira. Their goal isn’t to overpower Muzan, but to stall him until sunrise, his greatest weakness. Wounded and outmatched, the Corps holds out just long enough for the sun to rise and burn Muzan. In a last-ditch move, Muzan injects his cells into Tanjiro, turning him into a demon in hopes of surviving. But thanks to Nezuko’s emotional bond and Kanao’s well-timed antidote, Tanjiro returns to human form and Muzan is finally erased completely.
Who finally kills Muzan?
The sun delivers the killing blow. After hours of relentless fighting, the Demon Slayer Corps successfully delays Muzan long enough for the sun to rise, which burns him into nothing. Although no single person “kills” him, the collective effort—especially the sacrifices of Tanjiro, Obanai, Giyu, Sanemi, and others—makes it possible. Muzan’s own desperate move to survive by turning Tanjiro into a demon also backfires, ensuring his complete defeat.
Why is Muzan so scared of Tanjiro?
Muzan fears Tanjiro for two major reasons:
- Sun Breathing Lineage: Tanjiro is the spiritual successor to Yoriichi Tsugikuni, the only swordsman Muzan was ever truly afraid of. The moment Muzan sees Tanjiro’s Hanafuda earrings, he is triggered by the memory of Yoriichi’s unmatched power.
- Sun Breathing’s Divine Nature: Tanjiro’s mastery of Hinokami Kagura (Sun Breathing) represents the only Breathing Style capable of truly threatening Muzan’s existence. Unlike other techniques, it’s directly linked to the one warrior who nearly annihilated Muzan centuries ago.
As the battle progresses, Muzan realizes Tanjiro embodies everything he fears—legacy, purity, and indomitable will.
