The Ending Of Demon Slayer Season 1 Explained

"Demon Slayer: Kimetsu no Yaiba" is one of the most popular anime series at the moment. The beloved manga adaptation centers on Tanjiro Kamado, a teenage boy who discovers that his family has been brutally murdered. While trying to figure out what happened, he realizes his sister Nezuko isn't actually dead but turned into a demon — by the same demon that killed their family. Thankfully, Nezuko recognizes her brother and is able to resist killing people, and she accompanies Tanjiro on his quest to become a demon slayer. Throughout the first season of "Demon Slayer," Tanjiro trains while he tries to find a way to turn Nezuko back into a human.

While the first season was fairly straightforward, it sets up plenty of questions for future seasons. Thankfully, we don't have to wait too long for some answers, as the sequel film "Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train" is currently in theaters and will soon be available on streaming platforms. But until then, let's take a look at the ending of "Demon Slayer" Season 1 and the possible future of the show.

Season 1 ends with a perfect setup for the movie

At the end of Season 1, we see Tanjiro, Nezuko, and their friends Zenitsu and Inosuke board the Mugen train for their next mission: finding out what's happened to the 40 people who have gone missing on board. Tanjiro's Kasuagi Crow instructs them to meet with Hashira member Kyojuro Rengoku on the train, and the group heads off to their next adventure. This end to Season 1 is a perfect segue into the movie "Mugen Train," as it looks like most of the events in the movie take place on the mysterious locomotive.

The movie trailer also shows the group of demon slayers arriving in the Yoshiwara Red-Light District, where they'll have even more enemies to defeat. Since the show and movie are based on a manga series, fans who are able to get their hands on the books will know what's to come sooner rather than later. At any rate, it's sure to be exciting, and we can't wait to see what's behind the mysteries of the Mugen train.

The end of Season 1 introduces a new enemy

In the beginning of the last episode of "Demon Slayer" Season 1, we see the Lower Moons in an intense meeting with a disguised Muzan Kibutsuji, who's angry at them for not being strong enough for his liking. He then goes on to kill each member of the Lower Moons for different reasons, before asking for Lower One's last words. Lower One's response impresses Kibutsuji enough that instead of killing him, he injects some of his blood into Lower One's neck to make him more powerful. He then tells Lower One that if he kills a Hashira — or Tanjiro if he wants to be extra useful — he'll give him more blood.

In the last scene of the season, we see Lower One standing on top of the moving Mugen train, creepily smiling as the oblivious demon slayers prepare for their trip. Of course, now that the trailer for "Mugen Train" is out, we know that Lower One is the main antagonist of the film, seemingly luring train passengers into a hypnotic sleep state before killing them. The seamless transition from Season 1 to "Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train" is perfect for fans who are too restless to wait for "Demon Slayer" Season 2 to premiere. And if it's anything like the end of Season 1, "Mugen Train" will likely set the next season up perfectly.
