The entire Demon Slayer community is waiting for the Infinity Castle movies to release. The three-part movie will feature some of the greatest fights between the Hashiras and the Upper Moons. On top of that, the Demon Slayers will finally face the Demon King Muzan. If you are as excited as me for the upcoming movie, here are the most-awaited fights we will see in the Demon Slayer: Infinity Castle movies.
Spoiler Warning:
This post contains major spoilers from the Demon Slayer: Infinity Castle arc. Proceed with caution.
1. Tanjiro and Tomioka vs Akaza

Akaza emerged from the shadows in front of Tanjiro, Zenitsu, Inosuke, and Rengoku in the Mugen Train arc. At the time, Tanjiro wasn’t potent enough to fight the Upper Moon 3, so he couldn’t do anything. However, this fight is going to be personal for our protagonist, who has waited for a long time to avenge the Flame Hashira he admired the most.
While looking for Muzan Kibutsuji, Giyu and Tanjiro encounter Akaza in the Infinity Castle. Tanjiro doesn’t take the time to overwhelm the demon with several kicks and punches. Akaza gets stunned after observing the growth of the character he once believed was a weakling. On the other side, Giyu Tomioka’s senses awaken, and he ends up getting the demon slayer mark on his face.
The battle sequence also reveals Akaza’s backstory, and Tanjiro unleashes the ‘Transparent World’ attack, where the two heroes easily decapitate the enemy. But in the end, it’s Akaza and not the Demon Slayer who becomes the reason for the Upper Moon’s downfall.
2. Shinobu Kocho vs Doma

Shinobu Kocho had a hatred for Doma, as he killed her elder sister, Kanae Kocho, who was the previous Flower Hashira. It was a personal fight for Shinobu, so despite knowing that she doesn’t have a chance in the battle, she doesn’t shy away from attacking Doma after watching him devour a female disciple in Infinity Castle.
Shinobu tried to poison Doma with her Insect Breathing techniques, but it seems the demon was well acquainted with all of the methods. So, he doesn’t have to struggle to dodge the attacks coming from the opponent. Shinobu’s fight with Doma will be a spectacle to watch for fans, but it will be heartbreaking at the same time.
3. Zenitsu vs Kaigaku

In Demon Slayer, we have always seen Zenitsu acting as a coward, even though the boy is incredibly skilled at Thunder Breathing. However, he won’t act like a coward in front of Kaigaku. This fight will be personal for him, as Kaigaku, who is now the Upper Moon Six, was once a dojo brother of Zenitsu.
They both trained under Jigoro, who, sadly, had to commit seppuku to atone for Kaigaku’s betrayal. Kagiaku has brought shame to his mentor, but guess what? Zenitsu will bring Kaigaku down to his knees and make the boy regret becoming a demon. Forget the sleepy-head Zenitsu, as you will witness a furious and strong-willed version of the boy in Infinity Castle.
4. Inosuke and Kanao vs Doma

Shinobu will put up a great fight against Doma, but let’s say that things won’t end in a good way for the Insect Hashira. However, Doma won’t win the fight, as Inosuke and Kanao Tsuyuri will quickly join the battle. Interestingly, this fight against Doma will be personal for both Inosuke and Kanao. While Doma humiliates Kanao’s mentor and teacher in the previous fight, the Upper Moon is closely tied to Inosuke’s past.
So, Inosuke and Kanao Tsuyuri will work together against Doma for one primary thing – revenge. We have seen Inosuke surprise us with his fighting prowess against Daki and Gyutaro. Well, let’s just say that it was simply a taste of Inosuke’s overall strength, and we will get to see the full extent of his power in the Infinity Castle movie during the Inosuke and Kanao Tsuyuri vs Doma fight.
5. Mitsuri Kanroji & Obanai Iguro vs Nakime

The Love Hashira and the Serpent Hashira will go against the Upper Moon Four, Nakime. Nakime is the demon who controls the Infinity Castle, so it will be extremely crucial for the demon slayers to take down this enemy. However, they have to fight the demon on her turf, and, well, Nakime will manipulate the castle to gain an upper hand in this fight.
The Hashira duo will do everything in their power to bring down this enemy, and in fact, destroying Nakime would mean destroying Infinity Castle, which means Muzan will be exposed to the sunlight.
So, defeating Nakime is of great significance, but without spoiling much for you, let’s just say that it won’t be the good guys who will kill Nakime in the Mitsuri Kanroji & Obanai Iguro vs Nakime fight in the Infinity Castle movie.
6. Hashiras vs Kokushibo

This will be a multi-stage battle, and several Hashiras will go against the mighty Upper Moon One. Initially, we will see Muichiro and Genya teaming up against Kokushibo, and while it will be fun seeing the Mist Breathing against Moon Breathing, it won’t be any good.
After that, Sanemi will team up with his brother to bring down Kokushibo, which will be one of the greatest battles of the entire series. However, ultimately, it will be the fight between Stone Hashira and Kokushibo that will break the internet.
As of now, we haven’t seen anything from Gyomei Himejima, but when you finally see him in action in Infinity Castle, you will realize that all this wait was worth it.
7. Demon Slayers vs Muzan Kibutsuji

The Upper Moons are incredibly powerful, but they are not the biggest threat to the Hashiras. In fact, they are just pawns of the Demon King Muzan. Ultimately, the Demon Slayers will have to cut the head of the snake, or else Muzan will be able to create even more demons.
Fortunately, Infinity Castle will feature the much-awaited fight between Hashiras and Muzan. So far, we have only gotten a taste of Muzan’s power in the anime. The demon is so powerful that even Akaza, who killed Flame Hashira, couldn’t even lift his finger against Muzan’s power. So, imagine what the Hashiras will have to do to bring down this fearsome enemy.
There is another major fight that you will see in the Demon Slayer Infinity Castle movies, but we’ve omitted it here to curb the spoiler-heavy ending. You can read the Demon Slayer ending here if you would like.
