Demon Slayer Episode 11

Tsuzumi Mansion

The Tsuzumi mansion is the location where Tanjirou will find the next demon he’s meant to slay. However, he comes across a new companion while he’s making his way there. At the end of the previous episode Tanjirou came across a boy begging for a girl to marry him in the street, and this is his new companion.

The boy’s name is Zenitsu Agatsuma, and he’s a fellow member of the demon slayer corp. You may also remember seeing him at the end (and perhaps the beginning) of the Final Selection test. You’ll also recognize him as the electric boy from the OP.

But enough about Zenitsu for now, because the next section will be all about him anyway. Instead let’s talk about the setup to the next demon fight. Almost immediately after finding the mansion where the demon resides, Tanjirou and Zenitsu find two, young children.

Originally I figured these children might turn out to be demons, but that doesn’t actually seem to be the case (yet). Instead, the demon that lives in the mansion kidnapped their older brother, and the two kids followed it to the current location.

Tanjirou instructs the children to remain outside while he and Zenitsu defeat the demon and save their brother. And just to be safe, he leaves the box containing Nezuko outside with them so that she can protect them if the need arises (though he doesn’t tell them that).

But, the children get scared after hearing scratching sounds coming from within the box, and they run into the mansion with Tanjirou and Zenitsu. While I think the children will make it out of the mansion alive, I don’t believe their brother will be so lucky. He may even turn out to be the demon.

Zenitsu Agatsuma

From what we’ve seen of him so far, I can safely say that Zenitsu does nothing but detract from this series. I love characters who use electric-type attacks, but we haven’t even seen him do that yet other than in the OP. Also I can’t be sure the attacks we see are even elemental. The visual effects may just be effects to illustrate the power and nature of the attacks.

So why do I hate Zenitsu so much? Because he’s annoying. He whines. He complains. He’s always afraid. He chases after every girl he sees. He’s basically just a compilation of the worst traits from the Straw Hats from One Piece. At least they have redeeming qualities, but as of this point I can’t say the same about Zenitsu.

So why is someone like him a demon slayer in the first place?

He actually entered into the Final Selection with hopes of dying. He racked up a lot of debt and then was tricked into even more debt by someone who offered to pay off his original debt. But instead of dying, he somehow survived Final Selection due to his luck, not his skill.

That said, he does have one special trait. Just as Tanjirou has an extreme sense of smell, Zenitsu has an extreme sense of hearing. But even if he does turn out to be powerful in the end, I don’t think that will compensate for his annoying character.

As a final note on Zenitsu, while demon slayers are supposed to have companion crows, he has a sparrow instead. His sparrow doesn’t speak like the crows do though. And it’s revealed that while Tanjirou can understand it, Zenitsu can’t. So I don’t know how he figures out where to go next.

Taiko Demon

The Taiko demon is the master of the mansion Tanjirou and Zenitsu find themselves in. As much as I liked the Arrow and Temari demons’ abilities, I think the Taiko demon has a much more interesting one.

This demon has three taiko drums implanted into its chest and stomach. By tapping these drums, it’s able to rearrange and rotate any and all of the rooms within the mansion. It’s unclear whether this mansion in particular is linked to its blood art, or if this ability would work in any building.

Either way, this ability seems like it could make for a fairly interesting battle. Rather than our heroes simply fighting against the demon and his attacks, they’ll also be forced to fight against the environment itself.

At one point the Taiko demon also mentions that its prey escaped. It was particularly distraught because that person had “rare blood.” As far as we know for now, this could just be referring to blood type, but what if it means something more? What if in this world there are people with rare blood that are somehow different?

What if people with rare blood are the ones who gain blood arts upon being turned into demons? Sure, that would just shift the question away from, “what determines who gets a blood art” to “what determines who has rare blood,” but at least it would be a step in the right direction.

Anyway, I’m looking forward to the fight against the Taiko demon regardless of whether or not we learn anything new about demons from it.

Inosuke Hashibira

Alright, so Inosuke Hashibira’s name hasn’t been revealed in the anime yet, but now you know it. I needed to call him something for this review, and I figured that his actual name doesn’t really spoil anything so that’s what I’ll be referring to him as.

So who exactly is Inosuke? We know he’s a demon slayer, but not much more than that. The reasons we know he’s a demon slayer are because he wields Nichirin swords, and because he’s trying to kill the Taiko demon. But we don’t know if he’s a new demon slayer, or one who has been around.

You may recall from one of my earlier episode reviews that I mentioned there was one person to pass Final Selection who wasn’t shown to us previously. Inosuke may very well be that person, though it’s unclear why we never saw him before or after the exam.

He’s also the first demon slayer we’ve seen to have two Nichirin swords. And, what’s more, his swords are a bit more unique than any we’ve seen thus far. They don’t appear to have actual hilts, and their blades are notched. Did Inosuke make these himself?

We’re also already told Inosuke’s motives for wanting to be a demon slayer. He wants to acquire fame through killing powerful demons. And I have to say that while Zenitsu lowered my rating of this series, Inosuke raised it back up. I have high hopes for his character.

Oh, he also wears a boars head for some reason.

Demon Slayer Episode 10

Demon Slayer Episode 10

Together Forever

I don’t really think there’s all that much to discuss about this week’s episode of Demon Slayer: Kimetsu no Yaiba, but here we are anyway. Don’t get me wrong, there was some interesting information revealed during this episode, but not all that much actually happened.

This episode concludes the fights against Yahaba and Susamaru, but there wasn’t all that much left to conclude anyway. The fight against Yahaba was effectively finished in the previous episode. And as we’ll see, the fight against Susamaru is almost nonexistent.

At least a few of the gaps in this series’ plot and world building are filled in somewhat, but none of it really seems to matter anyway.

Before I get into the actual events of this episode, let me start off with what happens at the very end, we see the electric guy from the OP. Last time we saw him was the Final Selection exam results, and he doesn’t seem to have gotten any braver since then.

While I’m typically a fan of characters who use electric type abilities, and I think it looks cool in this series, I don’t know how much I’m going to like this character. From what I can tell he’s like a coward version of Sanji from One Piece. And by that I mean he’s a blonde womanizer.

At the end of this episode we see him begging some random girl to marry him, and in the ED we see him fawning over Nezuko. My assumption is that he’ll be to Nezuko as Sanji is to Nami, and I don’t find that to be a particularly interesting character attribute.

Yahaba’s Last Stand

Previously on Demon Slayer, Yahaba was decapitated by Tanjirou, thus effectively ending the fight. But, because anime, the fight didn’t actually end there. Instead, while dying, Yahaba finally decides to get serious and reveals the true nature of his power.

I don’t know about you, but I think I would have tried using the full strength of my ability before losing. So what exactly is this new power Yahaba reveals, and is it actually any better than his original power?

Originally he was able to shoot vector arrows out of the eyes on his palms. He could freely control these arrows, and whatever they came in contact with got forced in the direction they were pointing. These vector arrows don’t do damage themselves, but can be used to throw objects, or people, which deals damage.

Yahaba's eyes from the anime series Demon Slayer: Kimetsu no Yaiba
Yahaba’s eyes

The upgraded version of his power works a bit differently in a number of ways. First, his eyes don’t appear to be limited to one vector arrow each at a time. This in itself is already a substantial upgrade, but what really takes it over the top is that he can now make these vector arrows appear on his opponent.

Essentially, he no longer has to try to hit his opponent with the vector arrows, he can spawn them directly on his opponent so they can’t dodge them. For example, we see him spawn at least three different vector arrows on Tanjirou at a time, giving him no choice but to try to lessen the blows.

But this upgraded ability isn’t actually as good as I first assumed it would be when it was revealed. I assumed the different vector arrows would all pull Tanjirou in different directions simultaneously, but this isn’t the case. Rather than ripping him apart, the vector arrows activate one at a time, making them far less deadly.

Kibutsuji’s Curse

Alright, so Yahaba eventually disintegrates from having his head cut off by Tanjirou, but what about Susamaru? Tanjirou is in no shape to fight against her, so it’s up to Nezuko, Tamayo, and Yushiro to bring this second demon down.

However, we’re informed that demons can’t actually kill other demons, which is yet another plot inconsistency. We’ve already been told that demons frequently turn on and eat each other, so doesn’t that imply that they can kill each other? Or does the devoured demon just live inside the one which ate it?

Anyway, demons apparently can’t kill each other with the exception of Kibutsuji. It was previously revealed that Kibutsuji implants some sort of curse into the demons he creates, and this is how he controls them. Also recall that Tamayo was able to break free from this curse and Yushiro never had it to begin with.

If a demon inflicted with the curse so much as utters Kibutsuji’s name, they will be ripped apart from the inside. That alone isn’t enough to kill them, but this is where Kibutsuji’s blood comes into play. His blood, which is in their body, attacks demon cells and breaks them down, thus killing the demon.

Also we’re told that the reason Kibutsuji uses this curse on the demons he creates is so that they don’t group up together and attempt to bring him down. This also implies that his underlings are theoretically able to kill him, which again goes against the idea that demons can’t kill each other.

I think we’re getting to the point at which I have to start lowering my rating of this series due to all of its plot inconsistencies. Despite looking great and having a decent story, these inconsistencies are really adding up.

Filling in the Gaps

And now let’s just clean up some of the extra things that were revealed in this episode that don’t really seem to matter all that much. And the first of these things is the fact that Nezuko is just really, really physically strong. We don’t know why, but it’s confirmed that this is the case.

Next up we have the fact that demon blood no longer disintegrates (I’m sure that we saw it disintegrate earlier on in the series). This means that there’s now a way for Tanjirou to collect the blood for Tamayo to study. Also, Yahaba’s blood was never collected as far as I saw.

Then there’s the fact that Nezuko sees Tamayo and Yushiro as humans despite the fact that they’re demons. I brought this up in my review of last week’s episode, but it was actually brought up in this week’s episode. So why does Nezuko see them as human? Because she just does.

It’s then revealed that Tamayo and Yushiro are going to be leaving the city soon, and they offer to take Nezuko with them. Tanjirou decides to keep Nezuko by his side, but I think the real important part of these scene is that it informs us these two characters won’t be sticking around.

Sure, they’ll likely show up again later on in the series, but perhaps “good” demons won’t be as common as they seem to be.

And, finally, there’s the revelation that Yahaba and Susamaru weren’t actually members of the Twelve Demon Moons. Apparently the real Twelve Demon Moons are much stronger (as they should be) and have numbers tattooed onto their eyes (though I don’t know how Tamayo would know that).


That’s all for this week’s episode of Demon Slayer: Kimetsu no Yaiba. So what did you think of the episode? Was it good? Was it bad? Do you think there are a bit too many inconsistencies with the plot and world building? Let me know in the comments.

Demon Slayer Episode 9

Demon Slayer Episode 9

Temari Demon and Arrow Demon

During the previous episode we met Tamayo and Yushiro, two demons who are on the “good” side. Tamayo was turned into a demon by Muzan Kibutsuji, but she went on to break free from his curse which turns demons into his followers. She then turned Yushiro into a demon to save his life.

Despite being demons, these two, mainly Tamayo, work as doctors for humans and hope to one day “cure” demonization. But to do so they need to study the blood of many demons, mainly powerful ones who are close in ability to Muzan Kibutsuji. This is where Tanjirou Kamado comes in.

They need him to extract the blood of powerful demons, though exactly how this is done hasn’t yet been explained. I mentioned last week that demons, including their blood, disintegrate upon death, and so the demons theoretically must be kept alive until after their blood is analyzed.

Tanjirou Kamado

Unfortunately this series is only nine episodes in and already has a number of plot holes, so I doubt the extraction of demon blood will ever be explained in a way I’ll accept. In this episode the fact that Tanjirou needs to collect demon blood is reiterated while we’re shown demon blood vaporizing away, because why not?

There are other problems I have with this episode too which I’ll be covering throughout the rest of this review, but none of them are so extreme that they detract much from my enjoyment. They aren’t like the development at the end of Shield Hero episode 21 which ruined the episode for me.

Though, since this isn’t going to be covered in any of the other sections of this review, I will say that it makes no sense for Nezuko to view Tamayo and Yushiro as her family. They’re demons, and we were specifically told that Sakonji hypnotized her to see humans as her family and demons as enemies to be killed at all costs.

That’s two plot holes already this episode and I’m not even out of the introduction yet. Let’s see how many we can get.

Blindfold Technique

This next part I don’t consider a plot hole, but at the same time I have a feeling that it will never actually be explained, or at least explained well. What I’m talking about, of course, are the demon blood arts.

Despite receiving a large quantity of blood from Muzan Kibutsuji, so far Nezuko hasn’t shown any signs of having one of these techniques. However, Tamayo does have one of these techniques and it’s essentially a scent that works like a genjutsu from Naruto.

That’s fair enough, but it’s revealed that even Yushiro, a demon not produced by Muzan Kibutsuji, has a special technique of his own. So based on that we can assume that demon blood arts don’t have anything to do with the power gained from Muzan Kibutsuji’s blood.

Yushiro’s technique is the one used for concealing the house in which he and Tamayo live. He can essentially erase the presence of people and objects by masking their scent, sound, and appearance. We see him use this technique in combat to turn himself invisible when fighting Susamaru.

However, the real problem with demon blood arts doesn’t necessarily come from how they’re acquired, but rather what counts as one and what doesn’t. Sure, there hasn’t been much content for this series yet, but there a lot of abilities that are currently unclear.

By comparison, Naruto is a series for which just about every ability anyone has is explained. If you were to ask me about a particular character’s specific ability, I’d be able to tell you how its classified, what its effects are, and how exactly it’s performed. The same can’t be said for techniques in Demon Slayer.

A complex, yet easy to understand, “magic” system is pretty important for both suspension of disbelief and world consistency. Unfortunately, outside of Naruto (and Hunter x Hunter allegedly) I can’t think of many series that pull it off well.

Twelve Demon Moons

Perhaps you’ll remember that in a previous episode review, maybe the one from two weeks ago, I complained about how the introduction of Muzan Kibutsuji this early into the series was a negative? Well, that’s not all that uncommon in shounen series because it’s a simple way to set up an end goal.

I don’t think it’s a very sustainable way to set up an end goal, but if you aren’t planning for your series to go on as long as Naruto or One Piece then it can work just fine. However, I don’t think it’s a good way to set up a series that’s going to have any more than four cours, and even that’s pushing it.

Now, I’ll be honest, I don’t know how long Demon Slayer plans to run. I know this first season is going to be two cours, but I have no idea if that will cover the entire series or if there’s more that comes afterwards. My guess is that there’s going to be a second season, but we’ll have to wait and see.

Temari Demon Susamaru from the anime series Demon Slayer: Kimetsu no Yaiba
Temari Demon Susamaru

But why did I bring this up now? The reason is because this episode of Demon Slayer did another “very shounen” thing by introducing the Twelve Demon Moons, a group of powerful demons who work directly under Muzan Kibutsuji. You can think of this group like the Akatsuki, the Seven Warlords/Four Emperors, or even the Demon Lord’s Generals from any isekai.

The point is that I find this to be an overused trope that often times is there simply to force the plot along. It works a bit better in Naruto since it’s so long, and One Piece uses it in a much different way that I think works perfectly, but shorter series tend to use it in an almost villain of the week format.

Even JoJo’s Bizarre Adventure does it, and I personally think it detracts from that series. I’m fine with antagonistic organizations, but once you place a number on its members and say the protagonist has to beat them all to get to the final boss, it makes it feel extremely cheap.

Yahaba and Susamaru

The Temari and Arrow demons from this week’s episode are two of the Twelve Demon Moons. Susamaru is the Temari demon and Yahaba is the Arrow demon, which I found to be quite interesting. Susamaru appears to be a female, but the inclusion of “maru” in her name typically implies male.

But, Susamaru’s name isn’t the only interesting thing about this pair. What really struck me was the fact that despite being one of the Twelve Demon Moons, Susamaru doesn’t seem to have a demon blood art. Yes, she fights with Temari, but those aren’t a special ability.

In fact, what’s special about the Temari, the fact that they can seemingly change direction at random, is actually Yahaba’s vector (arrow) ability at work. The only thing special about Susamaru is that she can grow four more arms, but it’s unclear if this is a blood demon art or just something she can do because she’s a strong demon.

Yahaba is the much more interesting of the two. He has eyes on his hands which allow him to create and control vectors, which essentially dictate the direction in which energy moves. Basically he has a worse version of Accelerator’s vector ability from RailDex.

Though, while he can’t control the vectors of anything he touches, the arrows Yahaba shoots out of the eyes on his palms allow his vector ability to be used at long range. They’re also pretty versatile, making his fight against Tanjirou interesting to watch. I especially liked when Tanjiro did a flip to undo a twisting vector around his arm.

And, as far as we know, the eyes on Yahaba’s palms are the only eyes he has. We never see him open his real eyes, so we can’t be sure he has any. I was expecting him to reveal his true eyes towards the end of the fight, but he seems to have been killed before he could do so.

Interestingly, the bonus fact at the end of the episode was that Susamaru and Yahaba just met for the first time that day when they were ordered to kill Tanjirou. It’s impressive that they could work so well together on their first day, but what’s most interesting about it is that it means Susamaru was using her Temari without Yahaba’s vectors every time before now.


So what did you think of this week’s episode of Demon Slayer: Kimetsu no Yaiba? Are the plot holes too much for you, or can you overlook them? Also what do you think about the “magic” system and introduction of the Twelve Demon Moons? And, last but not least, do you prefer Susamaru or Yahaba?

Demon Slayer Episode 8

Demon Slayer Episode 8

The Smell of Enchanting Blood

Due to some of the things I plan to say in today’s review I feel that I first need to preface it by mentioning that I think Demon Slayer is a really good anime. In fact, it’s tied for the position of my highest rated anime this season. So don’t take the negative things I say about it as me hating the series.

With that out of the way I do think this series, or more specifically this episode, has a bit too much slapstick comedy. However, I think this can mostly be chalked up to the fact that this is a shounen series after all. If I wanted something completely serious, I should have watched a seinen.

Luckily, the comedy in this episode didn’t detract from any of the action, though it was interrupting the informative portions of the episode. If we’re being told about how the world works, I don’t want the explanation to be constantly interrupted by pointless arguing between characters for comedic purpose.

Anyway, the episode picks up where the previous one left off with Muzan Kibutsuji turning a random civilian into a demon in order to distract Tanjirou. While Tanjirou is holding the man, now demon, down on the ground, Muzan Kibutsuji is able to make a clean getaway.

And this seems to mark a pretty important point in Tanjirou’s development. He could have simply killed the demon and chased after Muzan Kibutsuji, but instead he attempted to restrain the demon. Previously he seems to have had no issue with killing demons, but perhaps it’s because he saw this demon as a human mere seconds earlier that he feels differently.

The Demon Doctor

I’m sure that Tanjirou will slay his fair share of demons in the future, but the fact that he didn’t this time is significant. It shows that he recognizes demons as humans who have been corrupted, not monsters who have been evil from the start.

This recognition also catches the attention of two new characters, Tamayo and Yushiro. Like Muzan Kibutsuji, these two are also demons who are hiding in plain sight. Unlike Muzan Kibutsuji, however, they aren’t actually evil, which I think is a little unfair.

I don’t really have a problem with there being other demons like Nezuko who aren’t evil, but this seems pretty early in the series to be introducing two of them. At this point we’ve met more good demons than bad demons with unique abilities.

Tamayo and Yushiro from the anime series Demon Slayer: Kimetsu no Yaiba
Tamayo and Yushiro

And, not only are Tamayo and Yushiro good demons, but Tamayo is a good demon with a unique ability. When she cuts herself, her blood releases a powerful scent which disorients those nearby. If you’re familiar with Naruto you can think of it as a scent-based genjutsu.

Tamayo also works as a doctor (for humans) despite being a demon. She reveals that she was able to break free of Muzan Kibutsuji’s “curse” by altering her body in some way so she no longer has the desire to eat humans. Similarly, Yushiro doesn’t have the desire to eat humans, but for a different reason which I’ll get to in a bit.

So how do these two survive if they don’t eat humans? Do they eat actual food? Do they sleep all the time like Nezuko?

Nope. Instead they simply drink the blood of humans. Due to the changes Tamayo made to their bodies, they require much less sustenance than standard demons and so can get away with only blood. They also purchase blood from humans under the guise of needing it for transfusions.

Bending the Rules

Okay, so here’s the portion of the review where I really discuss some of the issues I have with the episode and series at large. If you’ve been keeping up with my reviews of this series then you’ll know I’ve complained about plot points in one episode being revised an episode or two later. Well this seems to be continuing.

We were originally told that demons are created by the blood of other demons getting into a human. Then it was revealed that this isn’t really the case, and there’s only one demon who has this ability to create other demons. Now the series is backtracking once again and saying that actually other demons can do it too, just Muzan Kibutsuji is better at it.

In fact, Tamayo is one such demon who can turn humans into demons, and Yushiro is proof of this. Yushiro was turned into a human by none other than Tamayo, though he was the first demon she created in 200 years. Tamayo claims that she only turns terminally ill patients into demons, and only if she first gets their consent.

I assumed this to mean that most patients declined being turned into demons, and not that Yushiro is the first demon she created in 200 years because she failed all the other times. However, it was also worded in such a way that it could be read that it took 200 years to complete Yushiro’s transformation into a demon.

Anyway, the point is that Muzan Kibutsuji isn’t the only demon who can create other demons after all. Also the way he creates demons places some sort of curse on them, which Tamayo has discovered how to break. So does this mean that demons are actually only evil if they’re created by Muzan Kibutsuji?


Alright, so Tamayo supposedly knows how to break demons free from Muzan Kibutsuji’s curse, but does she know how to revert them back into their human forms? The answer is no, but she does believe that this is possible even if she doesn’t yet know how to do it.

In order to learn how to restore the humanity to demons, Tamayo first needs to learn more about demons in general. While she can perform all the experiments she wants on herself and Yushiro, the fact is that a sample size of two isn’t good enough.

And this is where Tanjirou comes in. Not only does Tamayo request that Tanjirou allow her to take samples of Nezuko’s blood, but she also requests that he gather blood samples from other, powerful demons. And luckily for him, two are about to attack.

The Temari and Arrow Demons from the anime series Demon Slayer: Kimetsu no Yaiba
The Temari and Arrow Demons

We don’t actually know anything about these two demons yet other than what little we’ve seen of them in this episode and the OP, so I’ll skip over them for today. But the real question now is how will Tanjirou deal with them?

When he kills demons their bodies disintegrate, so theoretically any blood samples gathered from them would too. Does this mean he has to capture these powerful demons alive so that their blood can be tested? Probably not since shounen series often aren’t worried about plot holes like that, but I can still theorize.

At least Tanjirou now has an actual goal besides simply defeating Muzan Kibutsuji. It’s not a tangible goal because there’s no way to know how many samples of demon blood he’ll need to gather before an elixir is created, but it’s a goal nonetheless.


What did you think of this week’s episode of Demon Slayer: Kimetsu no Yaiba? Are you okay with the series constantly backtracking and rewriting its lore? Do you think now was a good time to introduce more good demons? And how do you think Tanjirou will go about gathering demon blood samples?

Demon Slayer Episode 7

Demon Slayer Episode 7

Muzan Kibutsuji

Last week we learned of the existence of the first, or at least most powerful, demon, Muzan Kibutsuji. This demon is said to be the only one who can turn humans into demons, and so theoretically created every currently living demon.

We don’t yet know if he was the first demon to have this ability, and therefore the first demon, or if he’s simply the last demon with this ability. It’s also possible that there are other ways of becoming a demon, because if he’s the first, then how did he become a demon originally?

There’s still a lot we don’t know about the demons, and my hope is that one day we’ll have all the information. Where do they originally come from? Why does Muzan create more of them? And, how is it decided which demons develop unique traits?

Nezuko vs. the Triplet Demon from the anime series Demon Slayer Kimetsu no Yaiba
Nezuko vs. the Triplet Demon

That third question brings me to the fight between Nezuko and the demon I’ll be referring to as the “Triplet Demon.” We know that the Triplet Demon has a unique skill, and we also know that Nezuko does not. However, during this fight we learn that Nezuko is the stronger of the two.

So, why is this the case? Does Nezuko simply have a good match up against the Triplet Demon? Not quite. It’s true that her speed prevents the Triplet Demon from using his portals and her strength is overpowering, but that’s not due to any skill of her own, it’s due to how she was created.

The Triplet Demon makes a comment about how Nezuko must have received a lot of blood from “him,” the him referring to Muzan Kibutsuji most likely. We know that his blood creates demons, but now we know that more of his blood creates stronger demons, even if it doesn’t necessarily mean they develop unique traits.

So we know a bit more about the demons, but we still don’t know how unique skills are gained.


Meet Swampletics, my section devoted to the fight between Tanjirou and the two other forms of the Triplet Demon. While Nezuko was busy fighting the main body of the demon on the surface, Tanjirou slipped through a portal and into the demon’s realm.

This realm was described as a swamp; it’s completely submerged in murky water. Within this swamp, Tanjirou finds scraps of clothing from the various victims of the Triplet Demon.

But how is Tanjirou supposed to fight effectively while underwater? He’s not very maneuverable, he doesn’t have solid footing, and he can’t breathe. On the other hand, the Triplet Demon is a very fast swimmer and doesn’t seem to be affected by the lack of oxygen.

This is where my one and only real complaint about this episode comes in. Although this is a swamp, and Tanjirou is underwater, it’s said that there’s still some amount of air. In fact, he claims that there’s more air within this swamp than there was on the mountain where he trained with Sakonji.

I don’t know about you, but last time I checked breathing underwater is infinitely more difficult than breathing at an altitude where the air is thin. However, despite claiming that the air (or lack thereof) in the swamp is sufficient, after the battle concludes Tanjirou still needs to make a break for the surface to breath.

So what was the point of adding in that whole part about the air level in the swamp being no big deal compared to the mountain? It was tossed aside only a minute or two later, so what was the point of bringing it up?

Anyway, Tanjirou successfully defeats the Triplet Demon and asks him for information regarding Muzan Kibutsuji. Unfortunately, the Triplet Demon won’t tell him anything due to being more afraid of Muzan than of Tanjirou killing him. This is a trope I’ll never understand, but whatever.

The Big City

Although he just completed his first ever official mission as a demon slayer, Tanjirou already receives his next task. This time he must travel to Tokyo where there have been reports of a demon. This time around we’re given no other information about the case, like how we were told about the missing girls last time.

By the time Tanjirou arrives in Tokyo we can assume it’s been roughly two years, maybe a bit more, since the start of the series. During that time, Tanjirou hasn’t been to any big cities, but we do know that he has been to decently sized cities in the past.

Even so, he’s shocked by what he sees in Tokyo. Not only is the city much larger with many more people than he was expecting, but it seems that technology has advanced significantly since he was last out on the town.

I believe this is the first time we’ve seen electricity used in the series (correct me in the comments if I’m wrong) and yet Tokyo already has a trolley system. I get that Tanjirou was living out in the middle of nowhere, but seeing the difference between Tokyo and everywhere else he’s been so far is a bit jarring.

It honestly kind of reminded me of when I first watched Boruto and was shocked by how much the Hidden Leaf Village had changed. Although in that case something like 15 years had passed since the end of Shippūden, not a mere two years as is the case here.

Hiding in Plain Sight

So Tanjirou is in Tokyo on a mission, but decides to take a break from the hustle and bustle of the city. He finds a small udon shop on the outskirts of the city and is ready to dig in when he suddenly smells a familiar scene: Muzan Kibutsuji.

While Tanjirou has never met Muzan before, he knows his scent because it was Muzan who killed his family (allegedly) and turned Nezuko into a demon. I say allegedly because I’m starting to have my doubts about Muzan actually being the one to kill Tanjirou and Nezuko’s family.

After seeing how he operates from his interaction with Tanjirou in the city when the two finally meet, Muzan doesn’t seem like the kind of person to slaughter a family for no reason. I think what actually happened was that he turned Nezuko into a demon, and she was the one who killed her own family.

But if Muzan is in Tokyo, does that mean he’s the demon which Tanjirou has been sent to defeat? Probably not. It seems as though the demon slayers have no idea Muzan is in Tokyo, because otherwise they wouldn’t have only sent a rookie like Tanjirou.

We need to keep in mind that Tanjirou’s sense of smell is something unique to only himself and Sakonji, so the other demon slayers may have walked right past Muzan without even realizing who he was. He dresses and acts like a human, so why would they suspect him of anything?

In fact, Muzan even seems to have a wife and child, though it’s unclear if this child is actually his. My assumption is that it’s his adopted child and not actually his offspring. Though if demons were originally humans then I suppose they could still interbreed.

Either way, Muzan has the perfect disguise as a family man, much like Pride (or Wrath) From Fullmetal Alchemist (Brotherhood). And, a large city like Tokyo is the perfect place for him to hide. There are plenty of potential victims and he can easily blend into crowds.


So what do you think of this week’s episode of Demon Slayer: Kimetsu no Yaiba? Do you think Nezuko is going to develop a unique trait? If the series goes on for long enough I think it has to happen at some point. And, what are your thoughts on Muzan Kibutsuji?
