The story of the Flame Hashira Kyojuro Rengoku featured in the Demon Slayer: Kimetsu no Yaiba movie Mugen Train blazes a path forward into season 2 of the series.
The movie released in the US on April 23, 2021, and was a box office hit grossing $22,789,600 on the first day.
The film picked up where season 1 ended.
Tanjiro, Inosuke, and Zenitsu were sent on a mission to the Mugen Train to meet up with the Flame Hashira Rengoku.
This pairing is due in part to Tanjiro’s questions about his father and the Hinokami Kagura, which relates in some way to the flame breathing technique.
The season finale itself immaculately set up the plot and storyline for Mugen Train.
The film was action-packed with displays of various techniques and complex storylines.
Once Tanjiro and the others resolved the issue with the train, the film began to close with an intense battle between Rengoku and the Upper 3rd Demon, Akaza.
Rengoku had to keep everyone alive to fulfill his mission. Honoring his mother’s memory, Rengoku shows his true fighting spirit and sense of justice.
Rengoku responded that growing old and dying was the beauty of being human after Akaza offered to turn Rengoku into a demon so they could fight each other forever.
What made the ending heart-wrenching wasn’t just because of the death of the quirky but loveable Flame Hashira.
His wise words to Tanjiro, the flashbacks on notable scenes from his life, and the vision of his mother made Rengoku’s final moments more robust and tender.
All this while there was a demon arm sticking out of his chest.
Rengoku didn’t waiver in his core beliefs, but he did have a change of heart when it came to Nezuko, a demon who is a member of the Demon Slayer Corps.
Rengoku’s acceptance is significant because when Tanjiro first met the Hashira, Rengokuwas among those who could not accept Nezuko. He voted to chop off Tanjiro’s head before being put on trial.
The news of Rengoku’s death traveled quickly to the other Hashira. There were tears, expressions of anger, and a pledge to kill all the demons. Will Rengoku’s last words to Tanjiro hold up with the other Hashira who have yet to accept Nezuko?
The death of Rengoku may also foreshadow two things. First, someone will have to fill Rengoku’s place. It could very well be Tanjiro once he has a better grasp of the Hinokami Kagura and how to use it.
It could also spell death for more Hashira, particularly if anyone behaves rashly regarding Rengoku’s death.
Ubuyashiki, head of the Corps., praised the fact that there were no replacements between the meeting that was Tanjiro and Nezuko’s trial and the one before. However, Ubuyashiki’s reaction to Rengoku’s death also hints that his ability, aside from having a soothing voice, may have a clairvoyant aspect to it.
The expected release of Demon Slayer Season 2 is in the latter part of 2021.
