Kimetsu no Yaiba: The Movie – Mugen Train Review

Demon Slayer – The Mugen Train Arc

The Demon Slayer: Kimetsu no Yaiba manga was first published in Weekly Shonen Jump from February 2016 until May 2020. The series was written and illustrated by Koyoharu Gotoge. Demon Slayer tells the tragic story of Tanjiro Kamado and his sister Nezuko, who become orphans after their family is massacred by a demon. Nezuko herself is turned into a demon. Driven to return his sister to normal, Tanjiro embarks on a journey to find a cure. The series became a hit especially after the anime adaptation in 2019. As of December 2020, the manga had over 120 million copies circulation and surpassed One Piece as the highest-selling manga of 2019 and has gone on to sell over 82 million copies in 2020. 

Kimetsu no Yaiba: The Movie – Mugen Train is the first film from the series. A direct sequel from the anime series, the film retells the Mugen Train arc. In the anime, Enmu was given Muzan’s blood after the demon leader disbanded (and killed) the lower Twelve Kizuki. Meanwhile, Tanjiro, Zenitsu, and Inosuke are sent to join the Flame Hashira, Kyojuro Rengoku. The Hashira is investigating disappearances on the Infinity Train. Enmu is the cause of these disappearances. Enmu’s demon ability is dream manipulation. He can enter and control someone’s dream, it’s possible to kill them if he can destroy their “Spiritual Core.” Zenitsu, Tanjiro, Kyojuro, and Inosuke all get trapped in vivid dreams. Tanjiro dreams of his family, Zenitsu dreams of dating Nezuko, Inosuke dreams of being a “cave explorer” with Tanjiro, Nezuko, and Zenitsu as animal helpers, and finally, Kyojuro dreams of his family, particularly his father and brother. 

Kyojuro’s dream

Kimetsu no Yaiba: The Movie – Mugen Train has the task of humanizing Kyojuro. At this point in the series we only just meet him. It’s important to make us care about him, especially considering how this movie ends. His father, Shinjuro Rengoku, was the previous Flame Hashira. Shinjuro seems nihilistic, responding to Kyojuro’s announcement that he became a Hashira, with “it was pointless.” It unclear what made Shinjuro this way but it’s obvious that Kyojuro wants his approval. As the four children enter the dreams and locate the spiritual core’s they’re attacked by Kyojuro, Tanjiro, Zenitsu, and Inosuke. After everyone awakens, Tanjiro heads to the roof of the train to face Enmu. Tanjiro attempts to cut Enmu’s head off, but the demon keeps putting him to sleep. However, Tanjiro can wake up almost instantly each time. 

Eventually, Tanjiro decapitates Enmu using Water Breathing 10th Form: Constant Flux. However, Enmu is still alive because he’s merged with the train. The concept of a demon changing its form and therefore its anatomy is interesting. I wonder if the series will explore this further or if this is a one-off. However, the following fight between the demon slayers and Enmu wasn’t interesting. The use of CGI was distracting and I found the repetitive hacking of Enmu computer-generated flesh boring. Only when Inosuke and Tanjiro worked together to defeat Enmu did it become enjoyable. After the train crashes the most exciting fight begins. After Kyojuro teaches Tanjiro to stop his internal bleeding, something lands behind them creating a dust cloud.

Akaza, the Upper Rank 3 was revealed in the first Demon Slayer movie.
Akaza is the Upper Rank 3

Upper Rank 3 Akaza verses Kyojuro

It’s revealed that the Upper Rank 3, Akaza was the cause. He instantly tries to attack Tanjiro, however, Kyojuro uses Flame Breathing: Second Form – Rising Scorching Sun, splitting Akaza’s arm in half. The demon attempts to recruit Kyojuro, asking him to become a demon. Kyojuro refuses and Akaza attacks with his Blood Demon Art: Technique Development – Destructive Death – Compass Needle. Akaza and Kyojuro move so fast that Tanjiro can’t follow them. Throughout the battle, it becomes clear that demons have a natural advantage over humans in battle. No matter how much damage Kyojuro delivers to Akaza, the demon simply heals and does so quickly. It’s still possible to win but it must be done quickly. Until Kimetsu no Yaiba: The Movie – Mugen Train, those of us that only watch the anime was told that Hashira’s and Upper-Level Demons are at another level. 

Akaza and Kyojuro’s fight is a good display of the difference between the lower demon’s like Enmu and lower slayer’s like Tanjiro. Furthermore, the Upper Six can fight recklessly since the loss of limbs isn’t a concern, whereas, Demon Slayers much pace themselves, be disciplined, skilled, and cautious. Akaza and Inosuke note that Kyojuro’s form is flawless. When the fight reaches its climax, Kyojuro uses his Flame Breathing: Ninth Form – Rengoku verses Akaza’s Destructive Death: Annihilation Type. Kyojuro wounded both externally and internally is at his limit. After the dust clears, it’s revealed that Akaza has stuck his arm through the chest of Kyojuro. Undaunted, Kyojuro swings his sword into Akaza’s neck, Akaza tries to punch him but Kyojuro grabs his forearm. Akaza can’t break free and the sun begins to rise. After the blade digs deeper into Akaza’s neck he finally pulls free tearing his limbs off. He flees into the forest, as Tanjiro calls him a coward. 

Demon Slayer is about heart

Anime movies are often non-canon, creating lore that doesn’t impact the main series. In a lot of ways, this allows for more creative freedom. However, because Kimetsu no Yaiba: The Movie – Mugen Train is adapted from an arc in the main story it has an impact on the story. This movie feels more “real.” This movie’s central themes focus on the “beauty of being human,” and “the sorrow of death.” Kyojuro argues for humanity’s value. He says that “growing old and dying” is beautiful and humans are only “loveable and precious” because of this. He notes that the strength in humans isn’t based on the body. The film opens with Ubeyashiki and his wife, Amane walking through a graveyard for demon slayers. He laments all the death and hopes that it will end with the next generation.

It’s a foreshadowing of Kyojuro Rengoku’s death. I expect that Demon Slayer is going to kill off more of the “good” guys, Tanjiro and Nezuko might be safe but I’m not sure anyone else will be. What has set Demon Slayer apart from other shonen series has been the emotional maturity of Tanjiro Kamado. He is willing to sacrifice himself to protect others, however, unlike other shounen protagonists, he does pursue power for power’s sake. Tanjiro’s heartbreak at the end was probably the most impactful part of the film, he barely knew Kyojuro but was devasted as he knew him for years. Kimetsu no Yaiba: The Movie – Mugen Train tells a story that emphasizes that it’s not strength that matters, it’s the heart. 

Demon Slayer: Kimetsu no Yaiba Episode 25: Recap & Review

Season 1, Episode 25: Tsuguko, Kanao Tsuyuri

Tanjiro continues his quest to master 24 hour concentration. Accomplishing this wasn’t ever in doubt, especially considering Tanjiro’s work ethic. He of course takes thing to a bit of an extreme. He asks the trio, Naho, Kiyo and Sumi to beat him with carpet beaters if he fails to maintain his breathing while sleeping. Meanwhile, while Tanjiro is working so hard, Zenitsu and Inosuke still refuse to attend training. They begin to feel guilty for their laziness. Zenitsu and Inosuke are manipulated by Shinobu into finally training. As Zenitsu, Tanjiro and Inosuke fuss while training, we see Kanao’s tragic childhood. She was rescued from basically child slavery by Shinobu and Kanae Kocho. Kanao is still mute, but uses a coin to flip and determine her decisions.

The return of Mr. Haganezuka and his associate Kanamori was the main source of comedy in this episode. Haganezuka is unsurprisingly pissed that Tanjiro “snapped” his sword. Meanwhile, Kanamori presents Inosuke with two perfect indigo gray swords. Anyone watching this far knew what Inosuke would do to those perfect swords. He takes a large rock and chips at them, creating jagged edge swords like his old ones. Both Mr. Haganezuka and Kanamori leave angry, with Tanjiro being apologetic. Tanjiro finally recovers completely and manages to catch Kanao during tag. I’ve already predicted that this season will end on some kind of cliffhanger. At the end, we see a new demon killing people on a train. It’s grotesque, having at least two mouths and three eyes. It’s unlikely that they will wrap up this mission in one episode so I’m betting that it gets resolved in the following season.

Demon Slayer: Kimetsu no Yaiba Episode 23: Recap & Review

Season 1, Episode 23: Hashira Meeting

Tanjiro begins using his breathing technique to free himself. Giyu stops Obanai from interfering. Nezuko remembers her childhood. She begins to control her instincts, she looks away from Sanemi. Surprising to Sanemi, The Master takes it as evidence that she can be trusted. The Master then tells Tanjiro and Nezuko that they must go out in the world and defeat demons. Tanjiro states that he will “defeat Kibutsuji.” The Master kindly points that Tanjiro is nowhere near as powerful as he needs to be. He tells Tanjiro that he should focus on the Twelve Moon. Tanjiro and Nezuko are taken to Kocho mansion, Butterfly Manor.

They’re escorted into the infirmary. We see Zenitsu whining (as usual) about the pour tasting medicine. He needs the medication to regrow his shortened limbs due to being deformed by the venom. Zenitsu and Tanjiro happily greet each other. Inosuke lays silently in the bed besides Zenitsu. His voice has been damaged by the attack Father inflicted on him. Hoarse, he’s depressed by his lack of strength. Clearly this is going to be an opportunity for Tanjiro, Zenitsu, Inosuke and maybe Nezuko to gt some training. Meanwhile, the Hashira have their meeting. Demons are more active now and they need to increase their recruitment number.

Natagumo states that the quality of the non-Hashira’s members is terrible. However, it’s difficult for the Corps to recruit because humanity is largely ignorant of demons. Only those that have lost love ones to demons and are descendants of former demon slayers. The Corps have a good grasp on their problems. However, the ignorance of humanity can be solved by educating them. If the Corps taught them how to protect themselves from demon (wisteria) it would be harder for demons to kill them and get stronger. Right now the Corps are hidden from the public.

You could imagine that the Corps could become a military force, though that has other problems. Another thing that seems to cause them problems is the informal nature of how they choose demon slayers. Tanjiro was trained by a former Hashira, but his survival wasn’t really certain. The Corps seem unwilling to “hand hold,” at least not until after the final selection. Tanjiro is left to his own devices after he survives, given orders to fight but not how to fight. Basically, the leave them to fend for themselves which isn’t working at all. If they had a mentor continue to train with rookie demon slayers they would be better prepared than they tend to be.

Demon Slayer: Kimetsu no Yaiba Episode 22: Recap & Review

Season 1, Episode 22: Master of the Mansion

This episode introduces us to the dynamic and colorful Hashira. There are nine Hashira in all and they answer to Ubuyashiki Kagaya. We already meet Giyu Tomioka, the Water Hashira and Shinobu Kocho, the Insect Hashira. The new Hashira’s are Kyojuro Rengoku the Flame Hashira, Tengen Uzui the Sound Hashira who’s obsessed with flamboyance, Love Hashira Mitsuri Kanroji one of the two female Hashira’s with an unnecessary cleavage window, the constantly crying gentle giant, Stone Hashira, Gyomei Himejima.

Muichiro Tokito the Mist Hashira, he’s rather detached or indifferent. The Snake Hashira, Obanai Iguro the serious one with two colored eyes. Finally there’s Sanemi Shinazugawa, the Wind Hashira. He’s an asshole and I predict I might like him at some point. He’s covered in scars that appear to be self inflicted. He’s the most willing to kill Nezuko and Tanjiro. We finally get to see Ubuyashiki Kagaya the blind master. Generally, blind characters are exceptionally strong, I wonder if he is. Regardless, he’s very mild mannered and kind.

He asks the Hashira’s to accept Nezuko and Tanjiro. Surprisingly, due to the reverence they have for him, several of the Hashira’s continue to disagree. Even after reading the letter from Sakonji Urokodaki (in which we find out that Tanjiro, Giyu and Sakonji will commit suicide if Nezuko attacks a human) Sanemi still doesn’t care. He cuts himself, using his blood to try to get Nezuko to show her true self. He stabs her a few more times and opens the box. Nezuko steps out with an angered look on her face.

Demon Slayer: Kimetsu no Yaiba Episode 21: Recap & Review

Against Corps Rules

We finally get the final moments from Rui. Demon Slayer has established that only Muzan Kibutsuji is the true evil. While the demons he creates do monstrous things and must be stopped they were fundamentally human in the first place. Tanjiro is the demon slayer that understands this most, as his sister Nezuko, Tamayo and Yushiro are evidence that demon aren’t evil at their core. Rui’s background is like all the demons from before, tragic. Born in a frail body he could barely walk. Kibutsuji turned him into a demon, giving him a strong body. His father attempted to kill him. Rui killed him and his mother. He realizes that both his parents intended to commit suicide after they murdered him. Unfortunately, Rui is too late to notice that the bond he thought he never had with his parents, was severed by him.

Kibutsuji told him that it was his parent fault that they were killed for not accepting him. It’s an excuse that Rui never really believed but accepted it anyway. He missed his parents so much that his was never going to be satisfied by the fake family. In the present, Rui’s decapitated body falls just short of Nezuko and Tanjiro. Sensing the scent of grief from Rui, Tanjiro reaches out to Rui. Rui accepts that he will go to hell, never seeing his parents again. However, the seem to meet him in the afterlife. They promise to stay together, whether it’s in heaven or hell. Giyu steps on the remains of Rui, telling Tanjiro that he shouldn’t have sympathy for demons. He then realizes that he has encountered Tanjiro and Nezuko before. He does so just in time to stop Shinobu from killing Nezuko. Prepared to defend Nezuko and Tanjiro, he tells Tanjiro to run.

Shinobu is understandably confused by Giyu’s behavior. As Tanjiro is running he’s knocked to the ground by Tsuyuri, the girl from the Final Selection. Tanjiro tells Nezuko to flee, but is knocked out by Tsuyuri, who then pursues Nezuko. Meanwhile, Giyu has captured Shinobu in a head lock. Before things go too far, Kasugai crows arrive and inform everyone that they’re to take Tanjiro and Nezuko into custody. Inosuke, Zenitsu are to be brought to the Butterfly Mansion for further treatment. Finally, when Tanjiro awakens he’s treated to the sight of the Hashiras. I always thought that Tanjiro and Nezuko would come up against the rules of the corps and general prejudice against demons. I highly doubt she will be harmed, but I wonder if Tanjiro will be forced to leave the demon corps all together.
