Join Giyu and Tanjiro in their emotional fight against Akaza in Demon Slayer, highlighting the weight of their burdens and losses.
One of the most emotional and intense battles in Demon Slayer is Giyu and Tanjiro versus Akaza in the Infinity Castle Arc. This fight is not just about swords clashing and unbelievable techniques. It also dives deep into their pasts, their emotions, and the burdens they’ve been carrying.
These emotions start to stir in the hearts of our Demon Slayers as Akaza has killed Rengoku in the Mugen Train movie. Not because he had to, not because Rengoku posed some threat to Muzan’s grand plan, but just to prove he was stronger. That death shook Tanjiro to his core. The loss of Rengoku wasn’t just the loss of a mentor; it was a brutal reminder of how powerless he was. And that pain never really left him.
Fast forward to the Infinity Castle Arc in Demon Slayer. Akaza is back, standing in front of Tanjiro and Giyu, and all those emotions come rushing in. But this time, Tanjiro isn’t the same boy who chased after a retreating Akaza, screaming through his tears. He’s stronger. He’s trained. And alongside him is Giyu. Let’s discuss how this battle is one of the most emotional fights and how it brings us closer to the finale of the Infinity Castle Arc.
Giyu & Tanjiro vs. Akaza
From the very start of this battle in Demon Slayer, we knew this was going to be difficult. Akaza is a beast—his speed, his strength, his technique—it was all overwhelming. He doesn’t just fight; Akaza dismantles opponents. And he’s having fun doing it, as he has an impulsive need to be strong.
Giyu and Tanjiro take turns, each trying to find an opening. Giyu, with his calm and precise Water Breathing techniques, and Tanjiro, pushing himself harder than ever. They land blows, but Akaza just keeps regenerating. No matter how much damage they inflict, he grins, shakes it off, and comes back even harder.
At one point, Akaza recognizes them as formidable enemies. He genuinely acknowledges their strength. He even offers them the same twisted deal he gave Rengoku—to become a demon, grow stronger, and live forever. But they refuse, just like Rengoku did. Because for them, strength isn’t about power; it’s about protecting others, about fighting for something bigger than themselves. Moreover, their moral compass and sense of justice are so strong that they would never accept such a deal.
Breaking Down the Fight
As the battle rages on, Giyu starts wearing down. He’s given everything—even awakened his Demon Slayer Mark—but Akaza is relentless. Eventually, in this intense battle, after his awakening, where Giyu and Akaza fight as equals, Akaza shatters Giyu’s sword. At that moment, it looks like it’s over. But Tanjiro is still standing.
And then, when winning against Akaza starts looking like a dream, Tanjiro remembers what his father once told him—the key to true strength isn’t about overwhelming power, but about clarity, about seeing without distraction. And just like that, Tanjiro enters the Transparent World. His senses sharpen, his breathing steadies, and for the first time, he can predict Akaza’s movements before they happen. With this, he can hide his bloodlust presence, which throws Akaza off, preventing him from sensing Tanjiro. With one precise strike, Tanjiro beheads him in Demon Slayer.
The Fate of the Characters After the Fight
But even after being beheaded, Akaza doesn’t stop. His body keeps fighting without a head. His instincts, his drive, push him forward even as his body is on the verge of falling apart. And in this chaotic moment, we finally get Akaza’s full backstory.
He wasn’t always a demon. He was a broken child, a branded criminal, abandoned, left to fend for himself. His father, not wanting him to live as a thief, took his own life, as Akaza was stealing to provide for him, and as a father, he did not want his son to go down this path. And just when he thought he had found a place to belong—a dojo, a master who took him in, a woman who loved him—it was all taken from him. Poisoned. Gone. In his grief and rage, he slaughtered those responsible, and that’s when Muzan found him, turning him into a demon in Demon Slayer.
But now, finally, Akaza remembers. He sees his past self, his fiancee Koyuki, and the life he lost. And in that moment, he does something no other Upper Rank has done—he lets go. He stops fighting. He chooses to die, to reunite with the ones he loved in the afterlife.
The Aftermath of the Battle
When the battle finally ends, Tanjiro collapses. Giyu, despite being on the verge of passing out himself, shields him, standing over his unconscious form. They’ve won—but there’s no time to celebrate. Muzan is still out there. The real fight is just beginning.
Word spreads fast. The death of an Upper Rank shakes the demon world. Kokushibo, the strongest of them all, laments Akaza’s inability to grow stronger. Doma, Akaza’s so-called ‘friend,’ weeps dramatically, but knowing him, it’s all an act. And the Demon Slayer Corps brace themselves. Because if Akaza is gone, that means Muzan will be coming for them.
Conclusion
At the end of the day, this wasn’t just another fight. It was the collision of three warriors, each carrying their burdens. For Tanjiro, it was about justice, about avenging Rengoku, about making sure his sister could be human again. For Giyu, it was about proving himself, about living up to the Hashira name. And for Akaza? It was about finally remembering the humanity he had long since lost. It was raw, painful, and beautiful.
Just like this fight, the Infinity Castle Arc has multiple battles that are just as emotional and interesting to read. Don’t worry, anime watchers—this will be released as a three-part movie. We are excited to see it animated because it will do justice to these battles, bringing them to life with fluid motion as they were beautifully drawn. Demon Slayer’s animation is top-tier, and its use of BGM is also on point. We cannot wait for this fight and the entire Infinity Castle Arc to be released.
