The following contains spoilers from Demon Slayer: Kimetsu No Yaiba Manga and Anime.
Solo department has become one of the most famous anime over the past decade. Perhaps the biggest reason for its incredible popularity is its intense fighting scenes that capture Sung Jinwoo's development. But it should not come as a surprise as the most popular anime in recent decades was driven by high efforts involving protagonists who fought for the larger.
In Infinity Castle Arc, Tanjiro will go the same way he encounters an old rival who killed one of his dear friends. This will set the stage for an epic collision set to compete with Jinwoo's battle with Ant King. While both fights are intense, the former will be much more emotionally charged, and here is why.

Solo Leveling: 7 best fights in season 2, ranked

Hyper focus on Jinwoo made other characters seem irrelevant
Sung Jinwoo's fight with Ant King was intense and emotionally charged. Korea and Japan's future were at stake as the ants developed to get the power to fly. When some of the best hunters went to the abandoned island to fight for the bigger good, they initially enjoyed their strategy, which seemed perfect for the challenge.
If you are a hunter, I say you should be ready to be hunted.
But tragedy struck when Ant King arrived on the stage and attacked the raid party. When top hunters were killed in succession, it seemed as if no one were to survive. But Jinwoo just arrived in time to save the day.
The battle in Jeju Island was tragic and led to several deaths. Perhaps the most devastating loss was the one of my Byung-Gyu, the S-Rank Korean heal that originally did not even want to be there. Even Goto Ryui's end was shocking considering the hype behind him. But eventually all these characters acted as only a farmer, existing only to highlight Sung Jinwoos heroic acts.
Solo Living's Hyperfocus on his main person's character development made tragedies and the lives of other characters seem insignificant. While the fight with Ant King was undoubtedly brilliant, it did not have the same emotional weight as Tanjiro versus Akaza.
Tanjiro's struggle with Akaza will be emotionally charged
Fans can finally get the much needed emotional resolution
Each character in a story joins viewers only if they get the right development and depth. In Mugen Train Arc, when Tanjiro and his friends were sent to investigate mysterious disappearances on the locomotive, they found Rengoku who were already involved in investigating the case. For the viewers, he was not stranger because he had already debuted. But this arc gave Kyojuro the time to be himself and express his views and humanize him during the process.

Demon Slayer: 6 most expected battles in Infinity Castle, ranked
Infinity Castle is considered one of the best Arcw in Demon Slayer Manga. Here are the fights that fans expect in its anime adaptation.
Through his brilliant swords and leadership skills, Flame Hashira helped his comrades defeat the lower rank one of the twelve Kuzki. But the battle was far from over. Soon Akaza arrived at the scene and, and kept believing in its principles, Rengoku decided to protect his inexperienced comrades by fighting against the other people alone. The battle that followed caught Kyojuro's heroic spirit beautifully and gave the audience an opportunity to understand the low Hashira intimate. This created a band between Rengoku and the fans, which made his death so much more tragic.
Unlike solo niveness, the fans never really got closing when Akaza fled and was never confronted for their actions. The excitement has since kept, and now that Tanjiro is prepared to fight him in Infinity Castle, the efforts are higher than ever before.
The unfortunate evening Tanjiro was the witness of Rengocus's murder when he was unsuitable to fight. Flame Hashira's death had a deep impact on the young demon Slayer, and his last words have guided him ever since. For him, Avenging Rengoku means a lot, and he is determined to take down Akaza. As memories from Kyojuro rush through his head, Kamado will emotionally recharge when he puts his life on the line in the battle against the upper moon.
Everything you say is wrong. Your presence here is now proof. Everyone is a helpless baby when they are born. Same with you Akaza. You can't remember that, but when you were a baby … protected someone and helped you too. The strong protect the weak. Then they become weak stronger and help the weaker than themselves. It's the team of nature!
Unlike solo niveness, which often uses other characters for Jinwoo's development, Demon Slayer has honored their characters by highlighting their individual trips filled with trials and devastation. Because of this, Tanjiro's struggle with Akaza will not only be an emotional experience for the characters involved, but also for the viewers who have dropped their tears and look at Rengoku accept his death and use the last ounce of his energy to spread kindness and love.
The fact that the emotional resolution took so much time makes it more influence. That is why Tanjiro's battle in Infinity Castle will be much more emotionally charged and exciting than Sung Jinwoo's fight with Ant King in Jeju Island.
The first part of Demon Slayer: Infinity Castle Trilogy is scheduled to be released in the United States on September 12, 2025.
