Who killed Rengoku in the Demon Slayer movie? This is a question that has been on the minds of fans of the franchise ever since the film was released.

Rengoku, the Flame Hashira, was one of the most powerful warriors in the Demon Slayer Corps. He was tasked with guarding the entrance to the Demon World and was responsible for slaying countless demons. However, he was ultimately killed by a demon named Akaza.

Akaza is a lower-ranked demon who was not even supposed to be able to kill someone as powerful as Rengoku. However, he was able to do so because he caught Rengoku off guard and attacked him from behind.

This event left many fans wondering why Rengoku would let his guard down like that and how Akaza was able to kill him. There are a few possible explanations for what happened.

One possibility is that Rengoku simply grew complacent in his role as the Flame Hashira. He had slain so many demons over the years that he may have become overconfident and allowed his guard to drop.

Another possibility is that Akaza may have possessed some kind of special power or ability that allowed him to kill Rengoku. This is something that has not been revealed yet and may be something that is explored in future installments of the franchise.

Whatever the reason may be, Rengoku’s death was a tragedy that shocked fans of Demon Slayer and left many people wondering what could have happened differently.

What happened in the movie?

On the night of the ceremony to install him as the new Hashira, Rengoku was confronted by Enmu. Rengoku was unaware that Enmu had killed Shinobu Kocho and framed Tanjiro Kamado for her murder. Enmu revealed his true identity as a demon and attacked Rengoku.

Rengoku fought back against Enmu, but he was eventually overwhelmed and killed by the demon. His death caused great grief among the other members of the Demon Slayer Corps, who all held him in high regard.

Why did Rengoku die?

Rengoku’s death was an accident. The staff of the anime Demon Slayer: Kimetsu no Yaiba wanted to depict a scene in which Tanjiro Kamado tries to save his sister, Nezuko Kamado, from demonization by cutting off her head. However, before he can do so, Rengoku arrives and slashes the demon with his sword, inadvertently killing Nezuko in the process.

Who was responsible for his death?

At the beginning of the Demon Slayer movie, there is a significant time jump from the end of the anime. In this time, Tanjiro has become one of the strongest demon slayers and has even earned the title of “Kanroji’s Flame Breathing Technique User”. He is also shown to have taken on a new apprentice, named Rengoku. Rengoku is eager to learn and wishes to be just like Tanjiro when he grows up.

However, during a training exercise gone wrong, Rengoku is killed by aDemon. This event takes everyone by surprise, especially Tanjiro who had always seen Rengoku as his little brother. While Tanjiro is grieving over his death, the other members of the demon slayer corps begin to investigate who was responsible for his death.

The main suspects are Muzan Kibutsuji, the demon responsible for all the deaths of demon slayers; Akaza, one of Muzan’s loyal demons; and Susamaru, another demon under Akaza’s control. However, it is eventually revealed that Susamaru was not responsible for Rengoku’s death and that Muzan had killed him as part of a plan to get to Tanjiro.

This revelation leads to a final battle between Tanjiro and Muzan where Tanjiro finally avenges Rengoku’s death.

How did the other characters react?

After the death of Rengoku, the other characters were left to mourn his loss. They all gathered around his body and wept for their fallen friend. Some of them even blamed themselves for not being able to save him. It was a very emotional scene.

What does this mean for the future of Demon Slayer?

The death of Rengoku in the Demon Slayer movie has left many fans wondering what this means for the future of the franchise. Rengoku was one of the most powerful characters in the series, and his death will no doubt have a huge impact on the story going forward.

Some fans believe that this means that Demon Slayer is setting up for a major battle between humans and demons, with Rengoku’s death serving as a rallying cry for both sides. Others believe that this could lead to an even more dangerous situation, with the humans now being at a disadvantage against the demons.

No matter what happens, it is clear that Rengoku’s death will have a major impact on the Demon Slayer franchise. It will be interesting to see how this affects the story in the future.

What are fans saying about Rengoku’s death?

Fans of the Demon Slayer anime and movie are still reeling from Rengoku’s death. Some are wondering if he really is dead, while others are trying to figure out who killed him.

Rengoku was a fan favorite character, so his death has come as a shock to many. He was a powerful demon slayer, and his death has left a gaping hole in the anime’s plot.

There are many theories about who killed Rengoku, but no one knows for sure. The most likely suspect is Muzan Kibutsuji, the demon who killed Rengoku’s family. However, there are other demons who could have killed him as well.

Whoever killed Rengoku, one thing is for sure: his death has left a hole in the hearts of Demon Slayer fans everywhere.

How do I feel about it?

I’m honestly not sure how I feel about it. I was rooting for him throughout the entire movie, and I was really hoping he would make it out alive. But, in the end, he sacrificed himself to save Tanjiro and the other members of the Demon Slayer Corps, so I guess you could say it was a good death.
