After a hugely successful first season, the studio known for its adaptations of Fate / Stay Night brought Demon Slayer Movie: Infinity Train to Japan in late 2020.
This is practically a canonical sequel to the first season, and therefore falls between this and the announced second season of Demon Slayer. In the last episode of the series, after seeing the machinations of Kibutsuji Muzan, we see the quartet of protagonists approach a train. And it is right From this point the adventures of Demon Slayer Movie: Infinity Train begin.
Tanjiro, Nezuko, Inosuke and Zenitsu get on the train and meet Kyojuro Rengokuwho have favourited Hashira of the Flame, her goal. Tanjiro asks Rengoku about his new technique, but the senior swordsman knows nothing about it, even if he intends to personally train the boys. During the discussion, upon the arrival of the air traffic controller, Rengoku reveals that he is there because several hunters died on that train and are therefore conducting a personal investigation.
After a few seconds, Rengoku senses the presence of a demon, which immediately knocks down with its breath. Convinced that the danger is over, the hunters lower their guard and go to sleep. At this moment the technique of their real enemy Enmu begins, the demon to whom Kibutsuji Muzan had just added his blood. Enmus followers step into action and bond with the characters in the dream world to kill them. Thanks to the intervention of NezukoTanjiro, the only one who hasn’t fallen asleep, manages to wake up and has everyone saved.
After arriving on the roof of the train, he confronts Enmu with the water breath, but the battle seems particularly treacherous. In fact, its head is cut off, but the demon does not die. This is because he has absorbed the entire train and the people in him are his elixir of life. Zenitsu and Rengoku therefore begin to defend the passengers from the inside from the demon, while Tanjiro and Inosuke head for the locomotive. Their attacks don’t have much of an impact on Enm’s real bodies due to the power of the demon, but in the end they manage to blow up the car and thanks to the coordination work Then take off the real head from Enmu. Tanjiro is thrown off the badly wounded train when the demon disappears. Rengoku arrives nearby and advises Tanjiro to regulate his breathing to save himself and reduce the injury.
It all seems to be over when a sudden lightning bolt signals the arrival of another threat. Another demon appears in front of the group of protagonists: Akaza, the third of the Kizuki and thus one of the most powerful. Rengoku and Akaza begin to fight, with Akaza interested in the power of the Hashira. She tries to turn him into a demon by drinking Kibutsuji’s blood, but Rengoku keeps refusing as he continues to fight. The fight seems to be even, but Akaza’s wounds regenerate instantly as Rengoku slowly begins to take the attacks. The battle seems more and more towards the defeat of Hashira, as the latter decides to fall back on his most powerful move, the latest technology of the breath of the flame: purgatory.
With this attack Rengoku really does corner Akaza and despite a powerful attack, he manages to injure his neck. However, Rengoku’s blade is stuck and cannot continue while the sun is just rising. Tanjiro and Inosuke return to the field after being immobilized during the fight, but Akaza screams in despair and barely manages to escape into the trees after severing both arms. These protect it from the sun but not from Tanjiro’s blade, started with full force by the protagonist who pierces his chest.
Akaza still manages to survive and escape, while Tanjiro and Inosuke witness Rengoku’s death from his injuries. There The story of Demon Slayer continues with the second season, while the feature film is also generating excellent box office revenues in the United States.
