Latest posts by Asad Mehmood (see all)

Completely off-topic, but man figuring out the starting of these articles is the hardest part. Well, I guess you guys will have to bear with this candid beginning for this guide.

Would you believe it? I went on and binge-watched the whole 2nd Season of Demon Slayer. I relived those epic moments and artistic animation, only to share this incredible tale in this guide with you with some fresh memories and smiles.

Distributed over 205 Chapters, 23 Volumes, and 11 Arcs, Kimetsu no Yaiba is a modern-day masterpiece in the art of drawing Manga, Storytelling, Anime, and Animation. For me, it is among the Top 10 best modern animes, a title shared by Animes likes Attack on Titans, Jujutsu Kaisen, My Hero Academia, etcetera. 

With over 150 unique Anime series and 10,000+ Manga chapters under my belt, I will say I have seen and read a fair share of Anime and Manga in my life so far. Having experienced success stories like Dragon Ball Z, Naruto, One Piece, and Hunter X Hunter, I appreciate a new Anime taking the spotlight now.

As an Otaku, Demon Slayer‘s success in reintroducing Anime to the western world and capturing their hearts through its detailed animation and plot is genuinely admirable.

In this guide, I’ll be giving you an overview of the series and going through the sophisticated plot arcs of the story. This guide will help you understand everything about Demon Slayer Arcs and hopefully answer all your questions regarding the series.

Koyoharu Gotoge: The Alligator with Glasses

Born in Fukuoka Prefecture, Japan, on 5 May 1989, Gotoge is the mastermind behind Demon Slayer: Kimitsu no Yaiba. Gotoge uses an Aligator with Glasses as their avatar when delivering messages to the public. Gotoge participated in and won the 70th Jump Treasure Newcomer Manga Awards in 2013 with the work Kagarigari, a 45-page Demon-Slaying manga.

This One-Shot later became the foundation for Kimitsu no Yaiba, one of the top 10 best-selling mangas with over 100 million copies sold. Besides that, Gotoge had also created 3 other equally beautiful One-Shots before they moved on to work on Demon Slayer.

Now, Gotoge is working on their next epic tale, which according to them, is going to be a science-fiction romantic comedy story. Considering their success with Demon Slayer and numerous rewards with their One-Shots, it is safe to assume that this upcoming story will be one to keep an eye for.

Demon Slayer Story Arcs Asakusa Arc

Here are some important terminologies that you should know to understand the context and story of the series better. To make this guide easy to follow, here is an overview and a list of these terms.

The Hashira and The Twelve Kizuki: The Strongest Vs The Strongest

The Hashira and the Twelve Kizuki are the most vital members of the Demon Slayer Corps and the Demons at large, respectively. Both groups are critical to the plot and direct the flow of the series.

Hashira

Hashira is the highest rank in the Demon Slayer Corps that a Demon Slayer can achieve through training, working hard, doing missions, and climbing the rank ladder. In the English translation, the rank of Hashira is called Pillar.

Pillars are the leaders of the Demon Slayer Corps, akin to the Kages from the Naruto Series; each Pillar is a master of their specific Breathing Style and swordsmanship. At the beginning of the show, there are 9 active Hashira who practice 9 different breathing styles in the current setting.

The Twelve Kizuki

The “Twelve Kizuki” are the 12 strongest Demons at any point in time, who act under the direct command of the Demon King, Kibutsuji Muzan. Known as the Twelve Demon Moons in English, these demons are distributed in Upper-Ranks and the Lower-Ranks. The 1st to the 6th strongest belong to the Upper-Rank of the organization. In contrast, the 7th Strongest to the 12th are classified as the Lower-Rank Demons.

While excessively strong, the gap between the Upper-Rank Kizuki demons and the Lower-Rank Kizuki demons is massive. In terms of strength and fighting ability, the Lower-Rank Kizuki demons are as strong as a Hashira. But the Upper-Rank Kizuki demons are even more powerful, as each of them has killed Hashiras by dozens in their lifetime. 

For reference, it took the combined effort of sleeping Zenitsu, Inosuke, Full-Demon-Power Nezuko, Demon Slayer Mark Activated Tanjiro, and the Sound Hashira, Tengen along with his 3 ninja wives, to barely defeat Daki and Gyutaro. Which are the weakest of the Upper-Rank Kizuki Demons, Upper-Rank Six.

The Demon Slayer Breathing Styles and The Demon Blood Art

Demon Slayer Breathing Styles and Demon Blood Art are special fighting abilities utilized by the Demon Slayers and Demons, respectively.

Demon Slayer’s Breathing Styles and Swordsmanship

Demon Slayer Story Arcs Natagumo Mountain Arc

The Demon Slayers train under respected masters who teach them the special breathing techniques and swordsmanship, effective against demons.

All the Breathing Styles are derived from the original Breathing Style, known as the Sun Breathing Style. While there are 14 known variants of Breathing Styles, only Sun Breathing is known to possess the techniques to inflict severe wounds to Muzan.

Here is a list of all the Breathing Styles introduced in the series and their respective forms count.

Demon Blood Art

Tsuzumi Mansion Arc

Demon Blood Art is the general term used for various abilities, techniques, and spells at the disposal of a demon. As the name suggests, the Demon Blood Art utilizes the user’s blood to cast the respective ability, technique, or spell. If the user has less blood, their Demon Blood Art will drastically weaken and may be dispelled as well.

Throughout the series, 26 demons are shown to possess the ability to use Demon Blood Art techniques.

Besides unique Demon Blood Art powers, demons also have some shared supernatural powers like:

  • Accelerated Growth Rate
  • Biological Absorption
  • Disease Immunity
  • Enhanced Senses
  • Extrasensory Perception
  • Extrasensory Perception
  • Immortality
  • Information Sharing
  • Inhuman Physical Capabilities
  • Menacing Aura
  • Regeneration
  • Supernatural Blood
  • Unlimited Stamina & Endurance

All abilities possessed by a demon can grow significantly powerful as they consume more and more humans. On the other hand, most Demons require eating human flesh or drinking human blood to stay strong.

Some other shared weaknesses of demons are:

  • Sunlight
  • Nichirin Swords
  • Wisteria Flowers
  • Curse of Kibutsuji Muzan

Other Useful Terms

Rehabilitation Training Arc
Image from kimetsu-no-yaiba fandom wiki

Besides the ones mentioned above, the following terms are critical to the plot. Learning them will help you understand the series better.

Wisteria Flower

These flowers exist in the real world as well. In the Demon Slayer series, the Wisteria Flowers contain a specific poison that is effective against the demon-kind. The scent of these flowers is also actively avoided by demons, making them a valuable tool in protection against demons. 

Blue Spider Lily

Spider Lilies exist in the real world, but the blue-colored variants do not exist or have not been discovered yet. In the Demon Slayer series, the Blue Spider Lilies are the core ingredient of a particular medicine that can turn humans into pure demons like Kibutsuji Muzan.

Tsuguko

Tsuguko means Successor. In the Demon Slayer series, a Tsuguko is an exceptionally talented and strong fighter selected or scouted by a Hashira and trained under them to ultimately succeed them as a Pillar.

Kakushi

Kakushi is the term for a brigade of people who work as attendants to the Demon Slayer Corps. These attendants are not good in combat and help the Demon Slayers by providing several different services. These services include but are not limited to the following:

  • Providing medical treatment to Demon Slayers.
  • Cleaning up the battlefield after Demon attacks.
  • Serving as attendants of the Butterfly Mansion.
  • Sewing and repairing Demon Slayers’ uniforms. 
  • Transporting people to and from the Swordsmith Village.

Kasugai Crows

Kasugai Crows are unique crows who join the Demon Slayer Kasugai Crows Corps after completing the Kasugai Crows test. Though we don’t know the trial’s criteria, being a crow is unnecessary. These crows are assigned to Demon Slayers and have the task of delivering missions and messages to them.

Nichirin Sword

Nichirin Swords are unique swords made specifically to inflict lethal wounds on demon-kind. These blades are forged with the Scarlet Crimson Iron Sand and Scarlet Ore, both of which have the property to absorb sunlight. Sunlight is lethal to demon-kind; thus, weaponry made from these materials effectively against demons.

11 Golden Arcs of Greatness

The story of “Demon Slayer: Kimitsu no Yaiba” is elegantly distributed into 11 golden arcs. Each arc is focused on a particular theme or lesson conveyed through the plot’s events. These arcs are sometimes counted as 12, with the Final Arc being further distributed into two mini-arcs. I wrote this guide with 11 Arcs and mentioned the 2 mini-arcs, where due.

Now without further ado, let’s dive into the immersive plot of Demon Slayer: Kimitsu no Yaiba.

Arc #1: Final Selection Arc

Mugen Train Arc

The Opening Arc of the series, the Final Arc, begins with our introduction to the Kamado family via Tanjiro Kamado. The Kamado family belongs to a lineage of coal burners, and Tanjiro is the eldest Son of the late head of the house, Tanjuro Kamado. 

This arc tells about the brutal murder of the Kamado family and the demonification of Tanjiro’s younger sister, Nezuko. Furthermore, it tells about the pair’s journey to turn Nezuko back into a human and take revenge on the demon who murdered their family.

During this sad time, Tanjiro and Nezuko meet Giyu, the current Water Hashira. He belongs to the Demon Slayers Corps, an organization which’s purpose is to protect humans from demon-kind and ultimately eliminate the King of all Demons, Kibutsuji Muzan.

Giyu eventually guides Tanjiro to his mentor and advises him to train and join the Demon Slayer Corps to become strong and defeat Muzan. On the way, Tanjiro and Nezuko encounter their first demon in a temple. To their rescue comes Sakonji Urokodaki, their mentor. 

Nezuko is hypnotized to not eat humans and falls into a deep sleep for a year and a half. Tanjiro trains under Sakonji and gives the Demon Slayer Entrance Exam upon completion. Tanjiro becomes one of five survivors, and they are prompted to choose their Ore which will be used to forge their Nichirin Swords.

During their stay, Tanjiro sniffs a familiar scent, which leads him to none other than the murderer of his family, Muzan. This encounter results in Muzan becoming really angry and assigning two of his demons to kill Tanjiro.

Tanjiro and Nezuko also meet Lady Tamayo, a Demon doctor who freed herself from the curse of Muzan, and Yushiro, a young demon boy, who is Tamayo’s assistant. Tamayo treats Tanjiro’s wounds and offers help to defeat Muzan by studying demon blood and preparing a medicine that will turn them back to humans.

This proves to be a mistake on his part as Kagaya had already predicted Muzan’s plan and had prepared a counter-attack against him.

Kagaya blows himself up with a bomb laced with Wisteria flower poison. The explosion surprises Muzan, letting Tamayo inject the dedemonification medicine into Muzan.

Striking on this opportunity, the Stone Hashira, Gyomei Himejima slices Muzans head off. But to their surprise, Muzan does not die and reveals that the only way to kill him is exposure to sunlight.

After that, everyone is teleported to the Infinity Castle, where an all-out war between the remaining Hashira and demon slayers vs. the Twelve Kizuki and Muzan ensues. In this arc, the demon slayers successfully eliminate all the members of the Twelve Kizuki. However, they pay the price of the lives of many Hashira, including Shinobu.

FAQs

Question: In what Period does Demon Slayer Take Place?

Answer: The official synopsis for the series discloses that the plot occurs during Japan’s Taisho period (1912-1926). This theme is carried on throughout the series and is portrayed by the ordinary people’s actions, expressions, and habits. The Taisho period formed the roots of the Japanese lifestyle today. It represented Japan’s rise on the international scene and liberalism at home.

Formed well into words by Daniel Feibush in his article, “Demon Slayer’s Time Period: When Is It Set?“, “…Demon Slayer makes use of inspiration from the Taisho period in order to create a memorable world defined by its balance of modern and mystical elements.”

Question: What do Birthmarks Mean in Demon Slayer?

Answer: The Demon Slayer Marks are mysterious, mystical scar-like markings that manifest in certain conditions on exceptionally strong Demon Slayers. Some of these conditions are as follow:
The Demon Slayer Mark can only appear in Demon Slayers that survived the life-threatening conditions of having a heart rate over 200 bpm.
And a body temperature over 39° Celsius (102.2° Fahrenheit).
The precondition in unlocking it is that an individual directly related to Sun Breathing is present with it.

Once achieved, this mark can act as a catalyst and spread from the original user to other strong Demon Slayers through resonance. Achieving the Demon Slayer Mark grants the user the power of Bright Red Nichirin Sword, Enhanced Physical Capabilities, and Transparent World. These abilities enable them to become strong enough to fight Upper-Rank Class Demons on equal grounds.

The side-effect of using the mark is an extreme strain on the user’s body. Gyomei describes the curse’s effect as “paying one’s lifespan in advance in exchange for a greater physique.” Furthermore, Demon Slayers who have awakened the Demon Slayer Mark might die upon reaching the age of 25 years old.

Question: Will there be a Continuation of Demon Slayer after Chapter 205?

Answer: No, at the time of writing this guide (28 February 2022), the author has no plans to continue the series after chapter 205 of the Demon Slayer Manga. The story officially ended in the mentioned chapter. The author closed the chapter with a Thank You Note to all the followers, fans, and readers. In February 2021, Gotoge commented that their next project will be a science fiction romantic comedy story.

Demon Slayer Arcs Guide: Final Thoughts

Upfront Demon Slayer is a story about a selected Humanity Vs. Demons. However, it is more about the battles against demons that reside deeper within us. All of the demon-kind in the series arises from within the Humans, and only those with particular negative traits like a strong sense of jealousy, hatred, cruelty, and negativity are the ones who become demons.

Arc after Arc, Demon Slayer tells us life stories with many wrong decisions and cruel fates that lead specific individuals towards despair and demon hood. While Tanjiro and others fight them on behalf of humankind and remind us of valuable lessons along the way.

After every death comes a new beginning. But not before a flashback of the journey that led them to that conclusion. For me, Demon Slayer is about shaking us up from our trance of life to remind us of all the essential things that we have forgotten.

To that extent, my favorite arc from the series is the “Entertainment District Arc.” Because the demons in this arc represent Tanjiro and Nezuko in a darker light and what they could have become had they made a different choice.

Well, I hope you liked this Demon Slayer Arc Guide, and it proved helpful to you. Until we meet again, keep looking forward to the Season 3 of the Anime, which will probably be included in the Fall 2023 Anime Season or the Summer 2023 Anime Season.
