How would you say the demon slayer corp determines slayer's ranks??

Demon Slayer Rank Determination

While it's been explicitly mentioned in Rengoku Kyojuro Gaiden, fanbooks, and throughout Demon Slayer, Rank Determination becomes confusing when taking in other canon details.

Rank determination is something I've looked into before, and this is what I came up with. I don't remember all my reasons for some of these things, but we're gonna trust my past-self diligence XD 

How I believe Demon Slayer Rank Determination could've worked:

Individual rank determination after a mission in the Demon Slayer Corps involves several factors: the strength of the demon, the number of slayers needed to defeat it, the time taken to locate the demon, the number of casualties during the mission, and the extent of a slayer's involvement.

While assisting in missions can help a slayer climb the ranks, the highest rank achievable through involvement alone is Kinoto.

To reach Kinoe, a slayer must personally behead 50 demons or single-handedly slay a member of the Twelve Kizuki.

To achieve the rank of Hashira, a slayer must be Kinoe, demonstrate impeccable quality in their missions, and have mastery of their breath.

Most Demon Slayers take a long time to rise through the ranks because solo missions are uncommon. If slayers fought solo and killed even just one demon a month, they would reach the Kinoe rank in about four years. But that’s rarely the case. Most slayers patrol, respond if a demon is nearby, investigate, or join group missions.

Seeing how even Kyoujurou was on a mission investigating missing people from a train for around two months with the involvement of several demon slayers, I'd say Tanjirou, Inosuke, Zenitsu, Kanao, and Genya are rare exceptions due to their unique, evolved senses helping speed up investigations. (Smell, Feeling, Sound, Sight, and Taste)

So why is no one in the Kamaboko squad a Hashira?

Tanjirou, Inosuke, Genya, and Kanao never defeated one of the Twelve Kizuki completely on their own, and Zenitsu hadn't mastered his breath, only knowing the first form of Thunder Breathing.

But damn, they at least deserve an honorary title 😭.

I bet that if demons were still around after Muzan's death that Kiriya Ubuyashiki would've made exceptions. There being only two Hashiras left after all, and one of them was freshly without an arm 🧍. 

Also, I'm unsure how beheading credit is given when it comes to demons that could turn into multiple. Who knows, maybe Kagaya Ubuyashiki was like "Unfortunately, you've only killed 49.5 demons, so I can't make you a Kinoe yet :("

As always, I'll direct y'all to @demonslayedher for further details.

Her thoughts on the Corp Rank and Pillar System

[miloravioli]

On the patrol regions, I think Obani has to be close-ish to Tengen since he was able to get to the Entertainment district relatively quickly when shit hit the fan. He was there just after the battle ended and before the sun came up, which means the journey was probably 5 hours or less depending on how long it took the crows to get there. Also, how do you think they were divided when Tengen retired? Obvs he wouldn’t IGNORE a demon nearby, but not being on active duty, someone else would likely be assigned.

Hashiras Designated Patrol 'Regions' Pt.2

You are completely right about Obanai! I can't believe I forgot that he showed up after Tengen's mission at the Entertainment District.

While there is a chance that Obanai was just coincidentally in the area (since we know from Shinobu in Giyuu Gaiden that Hashiras do, to some extent, get free time and can travel outside of their regions), I assume the implication was that Obanai's designated patrol region was closest to Tokyo.

Honestly, it's all a mess because if Obanai were in Tohoku or Chubu instead of Chugoku or Shikoku, then during Pillar Training, Tanjirou + all the Demon Slayers would've been just running circles all over Japan in less than a month. Plus, all of the Hashiras and Kamaboko squad hometowns were in Tokyo prefecture (except Tengen, which remains unknown).

@demonslayedher theorizes that Muzan knew the blue spider lilies were in Kanto because the doctor was from there, resulting in most demon activity being centralized in Kanto (such as new demons appearing around Muzan). I like this idea!

So this time, I'll take a new approach and consider where all the Hashira would be if the Demon Slayer Corp were based in the Kanto region instead.

The Kanto region in Japan consists of seven prefectures: Tokyo, Chiba, Kanagawa, Saitama, Gunma, Tochigi, and Ibaraki.

Tanjirou's Hometown is in Mt. Kumotori, which straddles the borders of Tokyo, Saitama, and Yamanashi Prefectures.

As I mentioned in my last post, Giyuu went on a mission to Tanjirou's Hometown when it was still Shinjurou's patrol region. I theorized that if they meant the eight regions in Japan, then the reason Giyuu was outside his designated patrol region could've been because Shinjurou was already on a steady decline in his responsibilities.

However, in the case it all takes place within the Kanto region, it's much more likely that Giyuu's designated patrol prefecture would've been Saitama (ignoring the Yamanashi Prefecture since that's in the Chūbu region).

This leaves Kanagawa as the other closest to Tokyo, which might be where Obanai was based.

Google Maps says it would take 11 hours to walk from Kanagawa to Tokyo (with current-day terrain and roads). However, if the Hashira live closer to the edge of each prefecture, to quickly be able to get to headquarters or Master Ubuyashiki, and if Obanai was hurrying (even though he was late smh), then I do think he definitely could have gotten there in around 5 hours.

Sometime after Giyuu's mission on Mt. Kumotori, he got sent on another mission to a nearby mountain range (close enough that news of the Kamado family's massacre had already spread there).

In Giyuu's Gaiden, it says that the village Shinobu and Giyuu were at was a Northern rest point, so I assume the mountainside was the ones bordering the Gunma prefectures, which are part of the Kanto Mountain Range and Okuchichibu Mountains.

At this point in the timeline, there would be six Hashiras: Shinjurou, Gyomei, Tengen, Giyuu, Sanemi, and Shinobu.

Shinobu said she was only visiting for herbal remedies and that she'd taken a boat to get there.

Saitama Prefecture and Chiba Prefecture share a border, which is defined by the Edo River. With that information, I will be placing her and the Butterfly Mansion in Chiba (again, I ain't never been to Japan lol. Take this with a spoonful of salt). 

But then that brings the question of: Why did Shinobu and Giyuu get sent to Mt. Natagumo together? 

Well, to answer it simply, it could just be because at that time they had nine Hashiras with seven prefectures, so there was no risk in sending one of the Hashiras away from their designated patrol 'region' since someone else shared the area or could cover for them.

In my last post, I said that Sanemi and Obanai going to the demon-filled house together could've been because Nezuko had conquered the sun, therefore their designated regions would've had low demon activity. However, that mission happened before the emergency Pillar Meeting, so they probably wouldn't have had permissions to go beyond their designated patrol regions yet. For that reason, I would've said that Sanemi was also stationed in Kanagawa. Plus, if Ubuyashiki made no exceptions on missions outside their areas (due to not leaving them unguarded), not even for the Twelve Kizuki, then Obanai being sent to Tokyo after Tengen possibly means he shared a designated patrol prefecture.

BUT when the demon-filled house mission happened, Tengen had already retired, so the Hashiras would've had to spread out to one Hashira per prefecture. While there's a chance that prior to Tengen's retirement, Sanemi and Obanai were the besties that patrolled the same area, we'll never truly know rip. 

(Though I love the idea that the reason Obanai was so salty about Tengen retiring was because he and Sanemi would have to split up. LOL)

There's also a chance that Obanai didn't share Kanagawa with anyone and that he was only sent (with rare exception) because they had confirmation that Tengen was fighting a massively destructive Upper Moon nearby.

As for why Sanemi and Obanai were allowed on that mission together, perhaps Sanemi took over the Tokyo prefecture after Tengen and the demon-filled house could have been at the border of Tokyo and Kanagawa. (But that's just a theory. A GAME THEORY.)

So with all that, my most confident placements for where the Hashiras lived/ where their Designated Patrol 'regions' would be: Tengen and Kyoujurou were in Tokyo, Obanai in Kanagawa, Shinobu in Chiba, and Giyuu in Saitama. 

Gyomei, Sanemi, Muichirou, and Mitsuri could be in any of Gunma, Tochigi, or Ibaraki. I assume one of those who shared a prefecture had to take over Tokyo after Tengen's retirement.

Personally, I'm leaning towards it having been Sanemi. Although it's more likely that the shared patrol was in Ibaraki instead of Kanagawa, since it's the biggest in the Kanto region. However, I think Gyomei is fully capable of being responsible for that area alone.🤷 I also think Shinobu might've shared Chiba at some point since she's considered the weakest of the Hashira and already has a demanding occupation as a doctor + guardian (to 5 girls THEN 3 boys and a demon😭)

Some extra stuff: 

In the Kanto region, Tochigi Prefecture is known for having the most wisteria trees and many mountains, so I'd say that's where Mt. Fujikasane would be. Also, Saitama is considered the central prefecture of the Kanto region, so the Demon Slayer headquarters could be there. 

The only bother with that Demon Slayer headquarters placement is that we saw Tanjirou get carried from the headquarters in the morning and arrive at Butterfly Mansion while the sun was still out. If the Butterfly Mansion is in Chiba and the headquarters is in Saitama, then Google Maps says on foot it would take almost 13 hours. Though maybe it'd be possible depending on where exactly in the prefectures they were.

I'll leave the specifics of that up to the professionals (people who live in Japan, lmao). 

Alright, that was fun, and thank you for the question! Now I'm going to sleep.

Hashiras Designated Patrol Regions

In Rengoku Kyoujurou Gaiden, Kyoujurou is sent in his father's, Shinjurou's, place to exterminate a demon in Shinjurou's patrol region. When Shinobu expresses concern about sending a non-Hashira to handle possibly one of the Twelve Kitzuki, Ubuyashiki says that he can't give them a mission outside of their designated patrol regions. This shows me that he doesn't make exceptions on missions outside of their designated regions, even for the Twelve Kitzuki. 

At the time when Rengoku is at this meeting, there are five Hashiras, so they were likely stretched thin watching over all these areas. When the current story takes place, we start with nine Hashiras. 

It is possible that Shinobu and Giyuu watched over the same region at the time of the Mt. Natagumo mission, and that once Kyoujurou died that some of the Hashiras reaccommodated their designated patrol regions, with either Shinobu and Giyuu switching with Tengen so that he could take over Kanto (since the Entertainment District Arc takes place in Yoshiwara, a red-light district in Tokyo). Then the reason that Obanai and Sanemi went on a mission together to the demon-filled house could be because Nezuko had just conquered the Sun, so there wasn't as much demon activity in their regular areas.

The only contradiction with my theory would be that Giyuu went on a mission to Tanjirou's Hometown, which was in Mt. Kumotori, the Kanto region, when it still would've been Shinjurou's patrol region. Plus, in Tomioka Giyuu Gaiden, he was sent on a mission to another mountain range near Mt. Kumotori, where Shinobu already was. However, we can excuse Giyuu's presence at Mt. Kumotori, as him taking over when Shinjurou was probably slacking off, and in Giyuu's Gaiden, Shinobu said that she was only at that mountain range to get herbal remedies, not on a mission.

Now the question is, which region do each of the Hashiras patrol?

Japan has eight regions: Hokkaido, Tohoku, Kanto (where Tokyo is), Chubu, Kinki (sometimes referred to as Kansai), Chugoku, Shikoku, and Kyushu (which includes Okinawa).

Assuming that all the Hashiras live on the edge of the region they patrol, and that the Demon Slayer headquarters is at the center (likely around the Chubu region), we're going to have to rely a lot on anime logic for this.

Considering that walking from the edge of Japan to its center is a distance of approximately 1,500 km, not taking into account rough terrain, it could take around 3 to 4 weeks. Still, Hashiras can run fast enough that the average human eye can't catch them. We know they can travel huge distances in a short time.

However, remember that during pillar training, Tanjirou got from house to house in a day. That being said, we could assume that the order in which pillar training took place was based on distance and not ability.

Even if Tengen patrolled Kanto, he might not have moved yet, so perhaps his home and training still took place in Hokkaido. I only say Hokkaido because it makes it easier to work down the line, rather than expecting all the trainees to have to circle back. Muichirou's training came next, which would put him at Tohoku. After Tengen retired, Mitsuri's patrol changed to Kanto (it feels unrealistic, cause how does she have a whole mansion with cultivated beehives there in such little time? Oh well). We'll put Shinobu's Butterfly mansion in Chubu since everyone always goes there, and Chubu is the central region of Japan. Giyuu could be at Kansai since an injured Tanjirou got to him from Chubu. Obanai could be in Chugoku, Sanemi in Shikoku, and Gyomei in Kyushu.

So if Shinobu and Giyuu patrolled the same region, let's say Chubu, and then one of them switched with Tengen once Kyoujurou died so Tengen could patrol Kanto, then: Shinobu stayed in Chubu, Giyuu went to Hokkaido, Tengen to Kanto, then once Tengen retired, he went back to Hokkaido, Giyuu to Kansai, where Mitsuri had been, and Mitsuri to Kanto. 

I like the idea that Tengen and Mitsuri would be dedicated to keeping that area safe in honor of Kyojurou. Also, I think Giyuu isn't attached to where he's placed, so he's willing to move around

Now this is all speculation from someone who has never been to Japan, so I don't know how the areas look compared to where we saw each individual Pillar training take place. Also, the thought that human beings could cross such massive distances in such a short amount of time already makes this a big stretch; however, Demon Slayer is far from logical when it comes to time. 

There's a chance I interpreted this wrong, and by regions, they were referring to prefectures within Kanto since most of the story takes place there, and the majority of the characters' hometowns are in Tokyo. The Kanto region in Japan consists of seven prefectures: Tokyo, Chiba, Kanagawa, Saitama, Gunma, Tochigi, and Ibaraki.

However, if we interpret it this way, that would mean that all of the Hashiras reside within the Kanto region and that the rest of Japan isn't patrolled by Hashiras. I suppose it's possible, considering that they only have hundreds of demon slayers and that most of the demon activity seems to happen in the Kanto region.

Here is my dissection of what if they were all based in the Kanto Region instead. Which I now think is likelier.

Hashiras Designated Patrol 'Region' PT.2

Most of PT.1 is loose speculation, but PT.2 is way more solid.

If you see any inconsistencies or have any theories of your own, please share!

@demonslayedher has more put-together info on other demon slayer-related stuff, so go to her for all that!

I was curious what Kanae's height was since different sources said different things. Putting all these images side by side, I can deduce that she's likely 5'2 to 5'2 1/2. Younger Shinobu was 4'8.

Kanae was 15 - 17, and small Shinobu was around 12 - 14. Older Shinobu is 18 and 4'11 1/2.

While I was at it, I checked Kanao's ref sheet. At around 10 years old, malnourished Kanao was 3'9.

For the hell of it, here are all of them together.

See 15 - 17 year old Kanae's height next to 16 year old Kanao? Well, look at the following.

The image above with Kanae and Kanao would be of Kanae at 21 and Kanao at 16. Assuming they're standing at the same level, Kanae reaches almost 5'7 there.

Since Kanae's reference images were used for her when she first found Kanao, it's possible Kanae grew a little more before she died at 17, or that she would've grown more after.

However, even after messing around with the picture a bit, the anime's proportions don't exactly line up with the reference images. So take that all with a grain of salt

Hope fellow fans will have a use for this!

UPDATE!

After receiving some new attention on this post, I decided to double-check my information on Kanae and Kanao in Kimetsu Academy, in which I found two acrylic figures of their full body being sold on the Ufotable Official Store.

When I lined up their full bodies with the scene of them in the anime, I found that they were not standing on the same level.

Not only is Kanae wearing heels, BUT Kanao was floating above the level line.

We already know that canonly Kanao is 156 cm (5'1 1/2), but when I put her on the leveled ground, she was only 5'1.

So, after making both her and Kanae a little bigger while putting them on ground level, I can say that in that Kimetsu Academy scene, Kanae is actually 5'8, BUT she's wearing 1-inch heels, meaning that I went through all this work to tell you nothing new :D

My JJK oc Emiko Miyahira

Emiko’s curse ability allows her to suture any person or object she comes in contact with. This allows her to disable enemy’s in combat, an example being her sewing their limbs together. Her ability also comes in handy if someone is injured.

Reo Kagami

My JJK oc (Still haven't finished the anime, but I'm impatient)

His curse ability is a self-surrounding shield that reflects all damage back to who/whatever caused it. He can't keep it up for long tho rip.
