# Debunking Viral Demon Slayer ‘Facts’ That Fooled Everyone

## Summary

In this video, the creator fact-checks viral Demon Slayer 'fun facts' circulating on Instagram and TikTok, sorting them into actual canon, head canon, or unverified fan theories using official fanbooks and manga knowledge. The video also explores broader issues of misinformation in fandoms and the dangers of presenting headcanon as fact.

### Key Points

- **Reverse April Fools' fact-check** [00:21] — The creator announces a 'reverse April Fools' Day' video, examining popular Demon Slayer facts from Instagram and verifying them with official fanbooks and the manga.
- **Yoriichi and Inosuke's breathing styles** [03:00] — Confirmed true that Yoriichi and Inosuke created their own breathing styles without prior knowledge, unlike other characters who trained in existing styles.
- **Zenitsu inspired by cats?** [03:39] — The claim that Gotouge modeled Zenitsu after cat behavior is likely a fan theory; no interview or fanbook source could be found to support it.
- **Nezuko's muzzle inspiration** [06:07] — The claim that Nezuko's muzzle was inspired by a bamboo tea strainer is another fan theory without verifiable evidence.
- **Obanai's eating habits partly true** [06:35] — Obanai finds meals a nuisance and enjoys watching Mitsuri eat, but the specific '3 days without food' detail is unsupported in official sources.
- **Shinobu was the last Kocho** [07:19] — True: Kanae and Shinobu had no children, so Shinobu's death marked the end of the Kocho bloodline.
- **Tanjiro and Nezuko were not twins** [08:43] — The twin theory is disproven by official birthdays: Tanjiro (July 14) and Nezuko (December 20), confirmed by Ufotable.
- **Shinobu's plan was told only to Kanao** [10:44] — Contrary to the headcanon that Shinobu told everyone except Giyu, she only told Kanao, because she wanted Kanao to enact revenge if she died.
- **Goto hit Muzan with a car** [15:31] — This chaotic event is canon and happens in the manga during the final battle, as the creator vividly recalls.
- **The ambiguity of 'suki' in Japanese** [21:16] — The fanbook's statement that Sanemi 'seems to like Kanae' uses the word 'suki,' which can mean like or love, and Sanemi also uses it for Rengoku, so it cannot confirm a romantic ship.
- **Canon ships are limited** [28:31] — Only a few ships like Obanai/Mitsuri, Tanjiro/Kanao, and Zenitsu/Nezuko are canon; other pairings are headcanon and shouldn't be presented as facts.

## Transcript

aka April Fools' Day. I'm not going to lie, y'all. I don't like this day. I don't I I don't like the idea that for one day out of the year, we can lie to people and it's haha funny. I It just doesn't make sense to me. I'm also
someone who's probably a bit gullible to a lot of it and um it just it just frustrates me. So, we're going to do a reverse April Fools' Day video today and we're going to look up some of the most popular Demon Slayer fun facts on
Instagram and we're going to discover the truth of all of these together and the truth of all of these together and declare it actual fact, head canon, or needs to do more research. Now, I do have these two books with me right here
I might not know off the top of my head because after all, I am a regular human being that doesn't know everything about Demon Slayer. I know that might come as a shock, but for the sake of this video, we're going to have these here for
research and that sort of thing. And this is just for education purposes only, just so y'all know. I love fun and whimsical fandom related activities like having head canons. All I'm going to say is if you have a head canon, label it as
is if you have a head canon, label it as a head canon and not a fun fact. That's all I'm going to say. I literally started my entire TikTok journey talking about Avatar: The Last Airbender head canon. So, I am well aware that head
canons are fun. I start to get a little iffy on the idea of head canons when it actual canon, but at the same time, if you're just like, "This is a head canon of mine," I don't really care. It's when you start saying it's a fun fact when
But this video is all in good fun. I'm not trying to come after any of these creators. I am just merely going to point out when things are real and when understanding that whenever you see
research, please. But, we're going to dive right in, but before we do, don't the channel, and leave a comment your thoughts. And also, just putting a quick disclaimer out there, I believe a lot of these fun facts that we're going to see
you have not read the manga, put a pin in this video and wait until you've either read the manga or watched the movies. I highly suggest just reading the manga. It's very, very good. This video is It's going to have spoilers in
it. So, there's your warning. But, with that, let's get into it. Okay, so I'm actually going to be looking at these on my phone and screen recording this way. Usually, I use my computer for this, but I I'm trying new things. So, we'll see
if this works out the way I am hoping. Okay, so I literally just went on facts. >> [music] facts you probably didn't know. So, let's look at this very first one, which
I think Yeah, this has 22,000 likes. So, pretty popular. Demon Slayer facts you probably didn't know. Yoriichi and Inosuke are the only ones who created their own breathing styles without prior [music] knowledge. This is correct. They
that's presented in a way where they didn't have like previous knowledge. There are plenty of characters in the show that do create their own breathing show that do create their own breathing styles, but they already were learning
about it. They were being trained [music] for like a certain breathing style and then they created their own. Yoriichi and Inosuke both like Yoriichi is the, of course, progenitor of all breathing styles. Inosuke was just
living in the mountains and just created his own breathing [music] style. So, based off of my knowledge off the top of my head, this is correct. Gotouge was inspired to create Zenitsu after observing the behavior of cats.
Gotouge explains that Nezuko's nervous anxiety is based on how the cat reacts to a new environment. I mean, his behavior is very cat-like, [music] but Gotouge doesn't do a ton of interviews. So, this we're going to have
to try and find where this is coming from. I'm a big believer whenever people said this. Gotouge I said that." If you can't find it, it probably didn't
>> [laughter] >> That seems to happen quite a lot. Let's see if it's listed and I am looking at the core records book, which is a fan book. That's not to say that it's been written by fans. It was written by
Gotouge for the fans. That's why it's called an official fan book. Everything called a a fan book because it's like extra a fan book because it's like extra information for the fans. I saw someone
like, "It's in the fan book." They were like, "The fan book? You mean, my gosh, we're we're going the opposite direction." So, trying to find anything
in here that states that he's modeled after a cat. Not seeing anything listed after a cat. Not seeing anything listed just on his page. Yeah, this doesn't just on his page. Yeah, this doesn't seem to say anything just off the top of
what I'm looking at. It does not look like it says anything. This is going to like it says anything. This is going to be more about what Gotouge wrote before Demon Slayer, which is actually really helpful because I've seen a lot of fun
things that are in here." Okay, my last thing I'm going to look at is just use Google. Not going to use the AI thing because that's obviously the AI overview is so bad. So, everything that's on here are just
TikToks. I don't trust TikToks at all. So, everything that I'm finding either just says, "Gotouge it." with nothing linked, or calling it a fan theory. So,
I'm going to say this one is a fan theory. Again, if you can't find the actual interview anywhere, then it's probably not real. Nezuko's bamboo muzzle design was inspired by a real bamboo tea strainer
that the creator Koyoharu Gotoge saw in a Japanese restaurant. Here we go again. I I swear people are just like, "Oh, yeah, they "Where are the interviews?" It doesn't say it in the core records. All right,
we're going to call this one another fan theory because once again, there's theory because once again, there's nothing that I can find that has any nothing that I can find that has any evidence to argue for this fun fact.
3 days without being in peak condition, but with Mitsuri, he eats a little bit but with Mitsuri, he eats a little bit more. I think this one is true. He doesn't have to eat much to be okay, and that's because of his upbringing, but
where did the 3 days come from? So, the best I can find is in the core records book under Obanai's Taisho Whispers and Rumors, it says, "Iguro finds meals to be a nuisance. However, he always enjoys seeing Mitsuri happy chowing down."
After he enjoys a meal with her, even though he himself doesn't eat, he finds he has an appetite and then eats more than usual. So, can't find really the 3 days thing, but everything else within this fun fact is good.
Shinobu was the last Kocho, meaning when she died, her entire bloodline ended. >> [laughter] >> Um Kanae and Shinobu never had kids, so yes, that's the end of their bloodline.
Tanjiro and Nezuko were originally going to be twins. So, this I would believe is going to be in this book. No, this is their mangas. This is like the straight-up So, that's not in here. Whenever I see this kind of
not in here. Whenever I see this kind of stuff, I'm just very nervous to believe it. I've fallen into a rabbit hole of something else, and I feel like I have to bring this up. I I've lost a brain
read this, so I'm putting you all through the pain of having to read this. at me for saying that Tanjiro and Nezuko are twins, as Tanjiro clearly states that Nezuko is his younger sister. But, think about it. Nezuko was 12 when she
turned into a demon, so she is 12 until she turned back into a human. Not true, Her and Tanjiro spent 3 years at Urokodaki's place. Not true, it was two. It's legend like spelled out for us in the anime and the manga that it was 2
that he was at Urokodaki. Oh wait, that's right. He's 15. What's 15 minus 12? So, Tanjiro and Nezuko are 12 when making them twins. No. The Tanjiro's birthday is July 14th, and
Nezuko's is December 20th, which is confirmed by Ufotable, which means it's confirmed by Ufotable, which means it's canon. So, no. I have nothing to say to that. Okay. This one seems to be a fun fan theory.
This one seems to be a fun fan theory. Next. All right, this one is a real.
the end there to make all of them all the others look normal. Again, these are all fun head cannons. Like have these head cannons, that's fine. If you want to think of some things that aren't within canon that you love about a
within canon that you love about a character, then do it. I understand it. Like I said, I've made videos on it, but call them head cannons, not fun facts, because then when you start doing this, everyone starts just believing it. Every
single one of these, except for the last one, is a nice thought. It's a nice head canon. The first one, Shinobu never visited Kanae's grave because she thought she was a bad sister. Nothing to support
this. They both died thinking they saved each other. Sure, I guess. Mitsuri was still talking to Obanai not knowing he died a few minutes prior. There's nothing that states this. Shinobu told everyone about her plan
except Giyu because she knew he wouldn't allow it. Okay, this is my This is one of my biggest pain points. So, this one is not only clearly a head canon, but it also just goes directly against canon
because it is an actual plot point within the story that the only person within the story that the only person that Shinobu told of her plan was Kanao because that is a part of her and Kanao's story. So, essentially what this
Kanao's story. So, essentially what this head canon does, again, I will say, like have your head canons, have your theories, but if they're so incredibly against actual canon, I'm still going to call that out. And then if you go and
you also call it a fun fact, I'm going to be even more calling it out. Shinobu to be even more calling it out. Shinobu only tells Kanao about her plan. There's a reason for that. It is because she wants Kanao to be the one to enact
revenge should she die. Now, keep in mind, I see a A of people also say, cuz and how much hate she gets, even though like she went toe-to-toe with Upper Two, and Rengoku went toe-to-toe with Upper Three, both of them died, and Shinobu
gets all this hate and gets called a fraud and gets called weak and that sort of thing, while Rengoku is like this big hero, that sort of thing. Anyway, Shinobu did not go into that fight just like I'm going to die. She had other
plans. Yes, she knew that her plan might not work and that her only option might be to be absorbed by him and then thus like that allows Kanao and later on
Inosuke, which like he was an anomaly, Shinobu couldn't have planned that, and that they would be able to defeat him. Shinobu went into that wanting to different poisons that she was attacking him with is that she was trying to see
if that would work, right? But she knew it might not. So, she had like a backup plan that did involve her giving her life in order for her to take down Doma. She knew that Kanao had the ability to take on Doma, and she didn't know how
long it would take, but she did feel like Kanao had an obvious chance against This was an extreme pop point between the two of them about their sister
relationship, about how much Shinobu trust Kanao, about how much Kanao has grown, because she specifically says before she tells her her plan that Kanao She didn't want to tell her this plan until she knew Kanao could voice her
feelings on that plan to Shinobu, and Kanao still ended up agreeing to it. Shinobu did not tell anyone else. Shinobu did not tell Giyu, and no, she didn't not tell Giyu because she knew he wouldn't let her. If anything,
would have been like, "If that's what you think you need to do, then you need to do that." Giyu is one of the only people would be like that. Giyu almost figures it out in one of the light novels. We see Well, he doesn't almost,
he doesn't know because she hasn't told him. So, this just like is so opposite of what the plot is trying to show here just to support a ship. And
that's what annoys me about shipping culture and just about like this whole fun fact head canon culture of Demon Slayer is that now we're getting into the realm of you're not just making stuff up and labeling it as a fun fact.
You are making something up to support a ship that goes directly against canon and completely removes Kanao from the equation and like completely nullifies like her development and her story and that sort of thing to support the ship.
So, that's my biggest issue with that one. I'm going to because this one's video, I'm going to call this one at that. But let's just say the rest of these are all fun theories and head canons except for the
because that just happens in the manga at the end. Demon Slayer fun facts you probably know, probably don't know, or knew. Okay. All know that they make quite a bit of money, but we don't know exactly how
much they make. Aoi wanted a sister, so she was fiercely pestering Kanao to actually one of the doodles in one of the mangas. I don't know where it is off waste the time to go and find it, but that is definitely canon. Aoi burned her
open-chest uniform using oil to match Shinobu and Kanao. I don't think they were ever given that. I think that was a specific you got that when you were given the role of Hashira. I think. We know that Shinobu burned hers, but she
gave both Kanao and Aoi matches to do it. We don't know if they actually ended up doing it ever. Shinobu cares for Giyu as a friend. Shinobu thinks Giyu is a big doofus?
captain in the Kimetsu Academy. I haven't read enough Kimetsu Academy to see her in it, but I do believe she is the volleyball captain. Goto hit Muzan with a car when the final battle was about to be over. That's true.
That was like the most chaotic moment of reading the manga because I didn't know whether to laugh, whether to cry, whether to freak out, whether to hold my whether to freak out, whether to hold my breath. Like that was so so crazy at the
end of that battle. Like Muzan's turning into a baby. Tanjiro is nowhere to be found. Sanemi and Giyu are just trying their best. And then there's Goto in a car. It was so chaotic. Oh my gosh.
Kaburamaru pets Obanai's head when Obanai is upset. Fun headcanon. Fun fact, they are in the same final selection together. Okay, so this is in the second
fanbook. Now that is true. Okay. I was like I think this is true, but I never actually knew where that came from. Tengen likes to ruffle Muichiro's hair, picture of him kind of doing it. I guess that's like
are the only ones who can defeat an upper rank by themselves. Um I mean they're the only ones depicted as doing that. That doesn't mean that that they're the only ones who can. I have half a mind to think that Gyomei
would absolutely be able to take down Gyokko by himself, too. Not can, but they are the only ones who do in the story. Big difference, by the All right, next one. All right, here we go. Mitsuri couldn't hug Obanai one last
while fighting Muzan. confirm. I think that's just a observation. Both Muichiro and Genya died thinking that the other one had survived. Again,
have. Genya probably died thinking Sanemi hated him because he died before his brother could tell him he always loved him. So, the theory is, and this is again a theory, that Genya couldn't hear Sanemi as he was fading away
because his ears had already disintegrated. But, I I don't know if I disintegrated. But, I I don't know if I necessarily agree quite with this idea because demons are able to talk until the very end even when they don't have
anything to lend to their voice other than their mouth. I don't know. It's an interesting theory that he couldn't be able to hear him, but it's never like a a fact. It's never stated. It's like, okay, like maybe he didn't. Maybe he
okay, like maybe he didn't. Maybe he didn't know, but he also was like talking back to him. So, I think he knew. I I think it's pretty obvious that he could hear him and he knew that Sanemi was very distraught and saying,
think he was able to pick up on the fact that Sanemi did love him. Not to mention, too, is that Tanjiro told uh Genya that Sanemi's smell was that he loved him. Like, he he told him, "Like, hey, your
Like, he he told him, "Like, hey, your brother loves you. There's no hatred. There's no ill intent. I don't know why he's acting the way that he is, but he's Tanjiro said to Genya. Even though all the Hashira and Demon Slayers went to
heaven, Lady Tamayo went to hell. This is another fun theory. Not fun. I keep saying the word fun. These are not fun. Um this is a theory because in like the Um this is a theory because in like the final book, there's a drawing of all of
the characters who died facing one way and Tamayo's facing the other. I think where that is, though. And the theory is that they're all heading towards heaven while Tamayo's headed towards hell. I don't think
been. It's a theory. It's never been confirmed. So, not a a fact, a fun fan theory. We got to really be able to discern what the difference between a fact, a theory, a head canon is. Like All right, I think with that we're going
to end the video. I think the point of this video is really to just tell y'all like use discretion when you read fun facts and when you use them as arguments against other people, especially when it comes to ships. I know that video also
had like Sanemi was going to confess the day that Kanae died and that's just not true either. There's no canon material that leads us to believe that he was going to do that and there's barely any canon material that leads us to believe
that he even actually liked her. It that all comes from this Let's see here. Was it Sanemi? Okay. So, like what each Hashira thinks of all the other Hashiras. So, from the Stone
Hashira's point of view, so Gyomei, when he says something about Sanemi, he says, "Has a strong spirit. He's sensitive on the inside so he easily gets embarrassed. Apparently, he likes Kanae." I have a couple of things about
this statement. Number one is this is an English translation and I think I video. The translation in this is not very good. There's literal typos in that take everything that you read Take
a grain of salt because uh we're consuming this through a originally written in Japanese, obviously. And a lot of things are not one-to-one translation because the languages are built very differently.
So, when I read this, my first thought is well, what do they say in Japanese? Um I actually ordered the book in Japanese. Let's see Let's see if I can Japanese. Let's see Let's see if I can read it. Okay, hang on. Okay, so
This, of course, is the English print cuz it says Demon Slayer on it. So, what 115. Okay, it's going to take me a moment to read this. So, it says Kanai ga suki rashi, which
So, it says Kanai ga suki rashi, which means seems to like Kanai. Um it does use suki, which definitely can be used for love you ever hear in anime, they'll be like suki.
And then it'll get translated translated to I love you. You can also use suki when just referring to really anything you like. like Kimetsu no Yaiba. I'm not confessing my love, but I like it. Um
so, like there's an argument to be had that yeah, that's the nuance is seems to that yeah, that's the nuance is seems to like Kanai. Something of note is that like Kanai. Something of note is that Sanemi also says about Rengoku, suki.
Sanemi also says about Rengoku, suki. Like so, I'm talking about what? So, Hashira, and I'm reading the one about Sanemi right here. So, Kanai ga suki Sanemi right here. So, Kanai ga suki rashi, but then for Sanemi's
he says suki. So, you can argue the same thing about So, you can argue the same thing about Rengoku. It's like there's a lot of different nuances within the word suki. Obviously, if it was like aishiteru, it
would be like okay, he loves Kanai, like full romantic love, crazy. But, he says full romantic love, crazy. But, he says suki. And also like of note is pretty >> [laughter]
>> He says uh suki about Mitsuri. He says anmari suki janai, which means I don't like her that much. [gasps] >> So, it's not really much to go off of,
because Sanemi uses the word pretty openly. Uh Kanai no imoto nano desu. So, okay, about Shinobu Chowie chowie
Chowie chowie call Kakarot can I know emo don't know I'm saying this because I would not say that this just flat-out I would not say that this just flat-out says that Sanemi likes Kanai in a
says that Sanemi likes Kanai in a romantic way. Maybe he did Giyomei saying that he seems to like Kanai can mean so many different things. I have in the past been like oh I think my friend likes my other friend and I was totally
>> [laughter] >> Like romantically I thought like two friends like each other romantically and I was wrong. So like it can happen. He does mention when it comes to talking to Shinobu that
he talks to her a lot because she's kind of his sister which could also mean because he knows that Kanai is dead. So he enjoys talking to her because he knows that she lost her sister and he understands that because he's lost
siblings too. Like there's a whole lot of other nuance. I think reducing this just to romance. Oh, this means it's Canon that they liked each other and then adding on to it that uh, Sanemi was going to
well that's just straight up made up that that's definitely not anywhere and it also is very like let's just force something into a box and it's used often times as fuel against people who like
And here's the thing and I've seen this argument come up a lot and this is turning into such a tangent. I hope y'all like this type of video, but I've been seeing a lot of discourse on Twitter recently about people saying
that like Sanegiyo shippers are just so mean and disgusting and I have 100% believe that there are people out there like that. I see way more really weird
Sanemi and Kanai shippers and Shinobu and Giyu shippers than I have seen Sanemi and Giyu shippers. Most of the Sanegiyu shippers I come across were minding our business and all of us are aware that it's not canon. Yeah, we'll
each other because well, there's a lot of canon evidence that states that they don't actually hate each other. Um first of all, Giyu never hates Sanemi. In fact, in the anime he says that he wants to uh be friends with him. Sanemi
right now does kind of hate Giyu, but like that changes over time and that sort of thing. But most of the Sanegiyu shippers that I know, they're super cool canons, but they just chill out. They're never trying to be like it's canon. Cuz
it's not and we know that. Every time I say something about liking Sanegiyu in video on any platform, I have people that are like Shinogiyu. But Giyu loves Shinobu. But Sanemi loves
Kanae. Well, first of all, Kanae died 4 years ago. loves someone and that person dies, they're never allowed to love someone ever again? And the same could be said about San- uh
Giyu and Shinobu. You could argue like there's there's some argument for like maybe there's a little bit of chemistry there, but Giyu lives, Shinobu does not. Anyway,
turning into a bit of a tangent about shipping culture. Um shipping culture is shipping culture. Um shipping culture is just so weirdly toxic and it has been for a very long time. And it's one of those things that I've never been able
to understand because what do you mean like you're so opinionated over which character kisses which character that you'll like be which character that you'll like be weird and make stuff up and argue with
you could argue that that's what I'm doing right now. I am arguing with >> [laughter] >> I just think it's weird because I don't care. Again, I don't care if you ship Shinogiyuu. I don't care if you ship
TanKana. I think we all need to be real with ourselves and just live in the world of Uncanon. It is okay to live in the world of Uncanon. There are very few canon ships in Demon Slayer. Those canon ships are Obanai and
Mitsuri, yes, but people still have to force that into like a Obanai was going died, which is also really dumb because that's like a Western religion type thing and proposing with a ring was not necessarily never done in Taisho era
Japan, but not super common. That's a very Western style of proposing marriage very Western style of proposing marriage that has since like become very normal that has since like become very normal in Japan, but Taisho era was like right
when Western culture was starting to become a thing. Not to mention, again, as we see during that final battle is that he wanted to die to atone and marry Mitsuri in his next life. Like he explicitly says that he doesn't deserve
that. So, he would not have a ring in his pocket because he was never planning to marry Mitsuri. And like, yeah, that's sad, but that's a part of his story. character. And so, why do we just take our love for
like this romance between these characters and invalidate canon to make it fit into a new box. Just enjoy the ship for what it is. Um the other canon ships are of course like Tanjiro and Kanao, Zenitsu and Nezuko,
there's like the flashback characters like Hakuji and Koyuki, Yoriichi and Uta. Like all of those are canon ships because it's like actually they were together. Tanjiro and Kanao, there was in the final chapter like their
great-great-grandparents were like?" Well, it's showtime to know Tanjiro okay, they got married and had kids. Zenitsu and Nezuko like all of those characters had obvious descendants which means that they ended up together.
Everything else is just like see it how you see fit. Just don't invalidate the story to validate your ship. Like I don't know. That's That's where I'm like it's weird. I did not plan on this video going this route.
going this route. >> [laughter] it this far, leave a blue heart emoji in your comment. >> We're We're going to end the video there. Uh thank you so much for watching
the channel, and leave a comment your thoughts. And I will see you all I'm wearing my Tanjiro shirt by the way from Steady Hands. Um Tanjiro's on the
back. You just can't see. I'll see you all in the next one. Bye for now.
