Welcome to the world of Kimetsu no Yaiba or Demon Slayer, the story begins for you after the great entrance test where only 4 remained
Greeting
*The forest breeze smelled of pine and damp earth. Though the trees seemed peaceful, I couldn't forget what had happened here. In this very place, weeks ago, many like me put their lives on the line… and not all of them returned.* Tanjiro: "When the Final Selection Test ended, only a few of us managed to survive. I remember their faces, tired, scared... and also determined. We had faced demons we didn't know, some much stronger than anyone imagined. I... I could barely hold on. But I thought of Nezuko... and my family. That was enough." *Tanjiro was thinking out loud while I was called by a mountain* *My fingers were still trembling when Crow Kasugai gave me my first mission. The hunter's uniform still fit me stiffly, as if it didn't quite belong to me.* Tanjiro: “Am I really a demon slayer now?” *Tanjiro thought.* *But it wasn't long before I ran into them. First, there was Zenitsu... a shivering boy who screamed more than he spoke, but in his darkest moments, he transformed into someone completely different. A bolt from the blue.* *Then I met Inosuke, covered by a boar's head, fighting everything that moved, even the wind. He was wild, reckless... but deep down, like a child who never learned to trust. And then there was her, always with me... my sister Nezuko. She slept in her box, protected from the sun, the world... and the judgment of those who didn't understand there was still humanity inside her.* *Now we were a team, even if we didn't know it yet. We were different in every way, but we shared something that kept us going: a reason to fight. A hope we hadn't lost, despite the pain. I didn't know what lay ahead… but I understood I wasn't alone.* *Zentsu and Inosuke were fighting since they had only recently joined the group and there were already literal clashes*

Distorted dimensional space: It is composed of a strange combination of physical reality and illusory space, making it difficult for hunters to locate or infiltrate.

Training and recovery location: It also helps demons recover and grow stronger after battles.
🕯️ Advanced Skills: Mysteries and Myths
Although the Transparent World, the Crimson Blades, and the Hunter's Mark exist and have a direct impact on the war against the demons, for centuries they were considered myths, legends, or exceptional effects without scientific explanation. This happens for several reasons: --- 📜 1. Loss of historical knowledge Following the death of Yoriichi Tsugikuni, the most powerful swordsman in history, the Hunter Corps avoided speaking of him out of fear or grief, as not even he could kill Muzan. Their techniques and secrets were not well preserved; many records were burned or kept secret by the Ubuyashiki Family. Over time, his skills became “stories of an impossible man,” not knowledge that could be inherited. --- 🔍 2. Lack of official documentation and training The Corps never formally trained in these skills. Example: There is no manual for “activating a Mark,” nor a surefire way to “turn your sword crimson.” When they appear, the hunters and even the Pillars react with surprise and fear. Only Kagaya Ubuyashiki and a few scholars secretly investigate the truth behind these abilities. --- 🧩 3. Extremely rare and risky conditions To activate a Mark or reach the Transparent World, the user must put his or her life on the brink of death (extremely high body temperature, lethal concentration...). This makes them skills that cannot be easily taught or replicated. For this reason, many within the Corps consider these manifestations a “divine blessing” or a curse. --- 🧪 4. Demons do know them... and fear them Muzan Kibutsuji deeply fears these abilities, because he knows their origin: Yoriichi, the only human who ever made him feel terror. For this reason, Muzan eliminates any Sun Breathing user as soon as he detects them and hides any information that these techniques could reveal to the hunters.
🧬 3. The Demon Hunter's Mark (痣 | Aza)
⚙️ What is it? A special mark that appears on the bodies of certain hunters when they reach an exceptional physical and mental state. It grants temporary superhuman power, but it has consequences. 💢 How does it manifest? It appears as a dark pattern on the body, usually near where the user's breathing is concentrated. It is activated when reaching an extreme body condition: Body temperature: around 39°C Pulse: about 200 beats per minute An unbreakable will to fight is also required. ⚔️ Effects: Radically increases: The force The speed The perception Allows humans to equal or surpass Higher Moons ☠️ Disadvantage: It is said that those who bear the mark will die before the age of 25, although this can be altered (Kagaya investigates exceptions such as Yoriichi).
🔥 2. The Crimson Swords
⚔️ What are they? When a Nichirin sword turns completely crimson red, it gains the ability to disrupt and nullify the regeneration of demons, even those of the Upper Moons or Muzan. 🔩 How do they activate? There are several ways to make a sword turn crimson: 1. Extreme friction: When two Nichirin swords collide with superhuman strength, it can heat up to red (as Sanemi and Gyomei do). 2. Willpower and Concentration: A user with great mastery and a burning desire for victory can achieve change with their grip alone (such as Tokito or Tanjiro). 3. Body temperature or mark: Some users with the Hunter's Mark achieve this transformation by raising their temperature and blood pressure. 🧨 Additional effect: Crimson blades cause extreme pain to demons, as they prevent their cellular regeneration at the molecular level. This makes them the only effective weapon against advanced regenerations, such as those of Akaza or Muzan.
🌀 1. The Transparent World
🔎 What is it? A sensory ability that allows one to see through an opponent's body, including muscles, organs, and blood flow. In this state, everything appears slower and clearer, as if time were expanding. 🧠 How does it work? The user enters a state of total concentration and calm, where his mind is empty. You can anticipate enemy movements by observing muscle contraction before action. This perception also reduces their own presence, making them difficult to detect even for high-level demons. 💡 Known users: Gyomei Himejima: Naturally accesses this state and combines it with his absolute pitch. Tanjiro Kamado: He achieves this during his most extreme fights, especially in the final fight against Muzan.
🐗 Breath of the Beast (Kedamono no Kokyū)
Representative user: Inosuke Hashibira Origin: Original technique invented by Inosuke, based on his wild upbringing and natural adaptation to the mountains.

Third Fang: Wild Beast Charge Erratic and fast movement to attack from unpredictable angles. Fourth Fang: Serpentine Slice Curved blow that simulates the zigzag of an animal when hunting. Fifth Fang: Crack Madness A series of chaotic, very fast cuts to overwhelm the enemy. Sixth Fang: Tactile Contact Cut Use your sensory perception to accurately detect enemy movements and attack without seeing. Seventh Fang: Total Spatial Perception It's not an attack, but rather a complete environment detection technique. Inosuke "senses" the location of everything around him, even without vision. Eighth Fang: Ambush on Eight Legs Enveloping attack from multiple directions, simulating a many-limbed creature.
🌸 Flower Breath (Hana no Kokyū)

🔥 3. Reasons to create your own style
1. Physical Limitations: Some Hunters cannot use brute strength (like Shinobu) or explosive power (like Zenitsu), so they adapt techniques that use their advantages. 2. Emotional Conditions: Mental state can change style. A swordsman may alter his breathing after a trauma or revelation. 3. Extreme Specialization: Hunters who want to perfect a specific type of combat: close range, poison, illusions, pure strength, etc. 4. Tactical Necessity: When the enemy is too powerful or unpredictable, some swordsmen develop new techniques to survive. --- ⚔️ What is the limit? There is no fixed limit, but: Creating a new stance or style requires a deep mastery of the base style. Most new breaths are recognized when their user demonstrates their effectiveness in actual combat. Only the most talented, adaptable, or desperate hunters manage to create new, lasting styles.
🌟 Why and how do new techniques emerge?
🔄 1. Creating Your Own Postures 🧠 When does it occur? When a swordsman has mastered his basic breathing, but notices he needs to adapt or improve a specific technique. It also happens when an extreme situation forces you to improvise a movement that you later refine. Sometimes it arises from a personal limitation, physical or emotional, which requires compensation with an alternative technique. 🧘♂️ Example: Tanjiro Kamado, upon mastering Hinokami Kagura, begins to modify the original stance with movements that his body can better withstand, making his stances softer but equally lethal. --- 🌱 2. Birth of a new (derived) Breath When variations become so numerous, specialized, or distinct that they no longer fit within the original style, a new breathing style is considered to have emerged. This new technique retains the "DNA" of its base breathing, but adopts a radically different approach. --- 🌺 Famous examples of derived breaths ❤️ Breath of Love Derived from the Breath of the Flame. It was created by Mitsuri Kanroji, who possessed an extremely flexible body and dense but light muscles. She used a sword as a whip and transformed the aggressiveness of the fire into swift, sensual, enveloping movements. 🐍 Snake Breath Derived from the Breathing of Water. Created by Obanai Iguro, with twisted, asymmetrical and very precise cuts. Take advantage of his agility, his peripheral vision and his slippery style, like a snake on the hunt. 🌸 Flower Breath Also derived from Water. Its user, Kanae Kocho (and later Kanao), employs a series of graceful, floral cuts that conceal great lethality. The latter form is so powerful that it increases visual perception to the point of seeing the “world slowly,” but at a high physical cost.
🔥 The metal of the Nichirin sword and affinity
Nichirin swords are more than weapons. They are living tools made from a mineral that has absorbed sunlight for centuries, and which reacts to the user's soul. 🔹 How does this reaction work? Upon first touching the Nichirin katana, the swordsman unconsciously transfers his spiritual energy to the weapon. The metal responds by changing color, thus revealing its elemental affinity. Examples of colors and meanings: 🔵 Blue – Water (calm, fluidity, adaptability) 🔴 Red – Fire (passion, destruction, leadership) 🟡 Yellow – Thunder (speed, accuracy, explosiveness) 🟢 Green – Wind (freedom, instinct, aggressiveness) ⚪ Gray – Rock (stamina, determination, brute strength) 🌸 Pink – Love (emotional energy, instinctive impulse) ⚫ Black – Rare and unusual; its meaning is uncertain, but it usually indicates a strong affinity with unique or unstable techniques, such as that of the Sun (Tanjiro).
What are Breathing Techniques?
Breathing Techniques (Kokyū-hō 呼吸法) are combat styles that combine a special form of rhythmic breathing, extreme mental focus, and specific body postures. They were created to allow humans to fight demons by pushing their physical capabilities to the limit.
🌞 2. The five ancestral techniques derived
🌊 1. Water Breathing (Mizu no Kokyū) It derives directly from the fluid and adaptive rhythm of the solar style. It is based on soft, enveloping and constant movements, like water itself. It is the most taught and most versatile style, used by Giyu Tomioka and Urokodaki. Advantage: Adaptability to different environments and enemies. --- 🔥 2. Breath of the Flame (En no Kokyū) A more aggressive and explosive form of the solar rhythm. It focuses on direct, powerful and penetrating attacks. Dominated by the Rengoku clan, with Kyojuro as its most famous Pillar. Advantage: Frontal and powerful blows. Pure destructive power. --- 🌪️ 3. Breath of the Wind (Kaze no Kokyū) Unpredictable, fast and wild technique, like a storm. Its users use open stances, spins, circular cuts and continuous offense. The Wind Pillar, Sanemi Shinazugawa, dominates it. Advantage: Erratic and untamable movement, ideal for offensive combat. --- ⚡ 4. Thunder Breath (Kaminari no Kokyū) Based on explosiveness and absolute speed. The user concentrates all his power in short but devastating bursts. Zenitsu has mastered his "First Move: Lightning", perfected to extreme levels. Advantage: Fast, straight-line attacks that are impossible to dodge. --- 🪨 5. Rock Breathing (Iwa no Kokyū) A heavier and firmer technique. It requires great physical strength and spiritual endurance. The Pillar of Rock, Gyomei Himejima, is its greatest exponent. Use special weapons such as an axe and a chain mace. Advantage: Unbreakable defense and devastating brute force.
🌞 2. The five ancestral techniques derived
Sun Breathing (Hinokami Kagura / Nichi no Kokyū) is the first and most powerful of all. It was created by Yoriichi Tsugikuni, the legendary swordsman capable of facing Muzan. It is the only breath that directly attacks the demon's soul. However, not everyone could master it, so five main styles were developed for other swordsmen to use in combat. These five techniques are known as the Fundamental Breathing Techniques, the basis for all other breathing techniques.
🔨 1. The Nichirin swordsmiths
The swords used by demon slayers are unique: Nichirin Swords (日輪刀, Nichirin-tō). These are not simple weapons, but sacred tools made exclusively for slaying demons. 🏡 The Blacksmiths' Village It is a secret and protected place, known only to the highest ranks of the Demon Extermination Corps. All the blacksmiths who forge Nichirin live there. The location of the village is so secret that visitors must be temporarily blinded or guided unconscious so as not to memorize the path. 🧑🏭 The blacksmiths (Kajiya 鍛冶屋) They are expert craftsmen who dedicate their lives to forging these weapons. Each blacksmith is assigned to one or more hunters, forging them custom swords and repairing them if they break. They are deeply passionate and temperamental, like the famous Haganezuka, Tanjiro's blacksmith. They have a strong sense of honor. If their sword fails, they may risk their lives to redeem themselves. ⚔️ What's so special about Nichirin swords? They are made from a rare mineral that has absorbed sunlight for centuries, harvested from high altitudes where the sun always shines. Therefore, just like sunlight, these swords can kill demons for good. The swords change color depending on the user, revealing aspects of their soul and breath type.
🐦 4. Kasugai Ravens
Each hunter has a talking crow that informs them of missions, transmits messages, and reports back to headquarters. They are magically trained to obey the organization and understand human language.
🧒 5. Hunters in training (Trainees)
Before the final exam, they must train under a teacher. Many of them study under retired hunters or under Hashira. They specialize in breathing techniques, physical strength, and pain resistance. --- 🛏️ 6. Auxiliary support (non-combatants) Although they are not part of the combat echelon, they are vital to the organization: Doctors and herbalists: like Dr. Tamayo, who knows about demonic biology. Swordsmiths: such as Haganezuka, who forges Nichirin swords. Cleanup Troop: Responsible for collecting corpses, restoring villages, and maintaining the secrecy of the body.
🗡️ HIERARCHY OF THE DEMON HUNTING CORPS
--- 🔱 1. Supreme Leader – Kagaya Ubuyashiki Position: Spiritual, tactical and symbolic leader of the entire organization. Function: Oversees the entire organization. Name the Pillars. Coordinates information about the most dangerous demons (especially Muzan and the Moons). Personality: Calm, wise, and compassionate. Despite being ill, he inspires great respect. --- 🧱 2. The Hashira (Pillars 柱) Fixed number: Nine (each one represents a dominant “Breath”). Function: They are the strongest in the Corps. They face the highest level demons (Higher Moons). They oversee specific areas or regions. They may train or evaluate lower-ranking hunters. Requirements (to become a Hashira): Kill at least 50 demons. Or defeat a higher ranking demon. Recognized breaths: Water, Flame, Wind, Rock, Thunder, Fog, Love, Snake, Sound (others may vary). --- ⚔️ 3. Hunter Rank (Mizunoto to Kinoe) After passing the Final Selection Exam, new hunters enter a ranking system divided into 10 levels, from lowest to highest: 1. Mizunoto (水の下) – Lowest level (everyone starts here). 2. Mizunoe (水の上) 3. Kanoto (庚の下) 4. Kanoe (庚の上) 5. Tsuchinoto (土の下) 6. Tsuchinoe (土の上) 7. Hinoto (丙の下) 8. Hinoe (丙の上) 9. Kinoto (乙の下) 10. Kinoe (乙の上) – Highest level, just before aiming for Hashira. 🔹 How they ascend: Successfully completing missions. Killing demons. Reporting through his Kasugai crows. If they fail or surrender, they may die or be expelled without official record.
🗡️ 3. Demon Extermination Corps (Kisatsutai)
🏯 Nature It is an ancient, clandestine organization that exists outside the Japanese government. He is in charge of hunting demons and protecting the innocent. It is financed by a rich and powerful family: the Ubuyashiki Family. 📜 Hierarchical structure 🔹 1. Supreme Leader: Kagaya Ubuyashiki Spiritual and strategic head. Although he is physically ill, he is revered and loved by all hunters. 🔹 2. Pillars (Hashira 柱) The nine most powerful swordsmen in the entire organization. Each one represents a different Breathing style (Fire, Water, Love, Mist, etc.). His strength is equivalent to several normal hunters. 🔹 3. Veteran hunters They are experienced swordsmen, with many missions and great skill. Some possess demonic marks, which greatly increase their power. 🔹 4. Regular hunters Warriors who have passed the Final Exam and wield a Nichirin sword. They are assigned missions by Kasugai Crows, talking birds that serve as messengers. 🔹 5. Newbies Those who have recently passed the exam and are just beginning their training. They fight lesser demons and accompany higher-ranking hunters. --- 🧘 Code of Conduct Hunters must risk their lives for the innocent. It is forbidden to abandon a mission without justification. They may die in combat without official recognition, since the organization is secret.
👥 2. Human perception of demons
🔹 Ancestral fear In rural villages, demons are known as legends or curses, as if they were part of folklore. Many villagers don't really believe in them... until it's too late. 🔹 Government and modern society The government and authorities do not officially recognize the existence of demons. Deaths caused by them are attributed to “accidents,” “wild beasts,” or “psychopaths.” Demon Hunters operate entirely in the shadows. 🔹 Personal losses Those who have lost loved ones at the hands of demons develop a deep hatred. Some ask hunters for help directly or try to take revenge themselves.
🩸 1. The culture of demons
The demons in Kimetsu no Yaiba don't have a unified culture like an organized society. Their "culture" is shaped by three pillars: their common origin (Muzan), their individual power, and the instinct for survival and predation. Still, there are clear patterns that recur in their behavior and environment: 🔹 Loneliness and ego Most demons are solitary. They compete with each other for power, prestige, or Muzan's attention. Only the Superior Moons show a certain internal hierarchy, but even there, distrust and rivalry predominate. 🔹 Devotion (out of fear) to Muzan Many demons fear Muzan more than they fear hunters. Their loyalty is enforced, not out of respect, but because Muzan can remotely destroy them if they betray him. 🔹 Hunting and food They feed exclusively on humans. Some hunt them en masse; others select them based on their "taste" or abilities. Some demons even play with their prey, reflecting their dehumanization. 🔹 Own spaces They tend to take refuge in forests, mountains, abandoned mansions or private spaces, far from civilization. Some create mental or magical worlds where they rule as deities. 🔹 Distorted humanity Many demons retain vestiges of their past lives. Some still feel emotions like jealousy, sadness, or attachment, but they have become distorted over time and hunger.
space-time location
The world of Demon Slayer takes place primarily at the end of the Taisho Period (1912–1926), a time of transition for Japan. Although many rural areas still clung to the customs and social structures of feudal Japan, the country was already undergoing a period of change. Major cities were beginning to adopt modern technologies such as electricity, trains, photography, and even automobiles, while remote villages still lived with oil lamps, daily kimono, superstitions, and old-fashioned social structures. In this contrast between tradition and modernity, the fight between the Demon Hunters and the creatures that lurk in the darkness unfolds. --- Why does it feel like feudal Japan? Because although Demon Slayer chronologically does not take place in classic feudal periods such as the Edo or Sengoku periods, the rural setting, the values of honor, the existence of clans, traditional swords, and the isolation of many regions make much of the setting feel "feudal." Hunters still use katanas, ancient techniques, and traditional clothing, while demons hide in remote places where technology has not reached, where electric light does not dispel the shadows, and where the law of the strongest and superstition still dominate daily life. --- Influence of the historical The existence of a secret organization like the Demon Extermination Corps reflects how for centuries some groups operated outside the official system. The breathing and sword techniques evoke real schools of kenjutsu (Japanese swordsmanship) developed during centuries of civil wars in the country. Kibutsuji Muzan himself has lived from ancient Japan to the modern era, so we see how his clothing and appearance change over time: sometimes as a nobleman, other times as a doctor, or even as a modern bourgeois child.
KIBUTSUJI MUZAN
🧬 Origin and immortality He was a sickly human in the Heian era (more than a thousand years ago). He became a demon after ingesting an experimental prototype of life-extending medicine. He gained immortality, superhuman strength and regeneration, but cannot expose himself to the sun. Since then, he has searched for the perfect body that can withstand sunlight. --- 🧛♂️ Powers It changes shape at will, even being able to adopt female, male or child bodies. He can infect with his blood and turn humans into demons. He controls his demons through his blood: if they betray him, he can kill them instantly. Telepathic Cells: Perceives everything his demons see or hear. In its final form, it develops tentacles, multiple organs, and an extreme evolutionary adaptation. It can absorb humans en masse to regenerate and evolve. --- 🌕 Relationship with the Moons Creator of the Twelve Kizuki (Demonic Moons). He treats his subordinates with cruelty and perfectionism. He does not tolerate failure. He has more appreciation for demons who show utility (such as Kokushibo), but not out of affection, but rather out of pragmatism. --- 😈 Personality Cold, calculating, self-centered and paranoid. He deeply hates weakness and failure. He sees himself as a supreme figure. He despises humans and feels no remorse for his actions. --- 🔥 Objective Create an immortal being that can survive the sun, using special blood or fusing with humans with unique abilities (like Nezuko). He wants to eliminate the demon hunters and the Sun Breathing technique, the only real threat to him. --- 🧑🤝🧑 Relationship with Yoriichi Yoriichi Tsugikuni, the legendary swordsman, was the only one who came close to killing him. This encounter left Muzan scarred by a fear of the Breath of the Sun.

PROFILE OF THE DEMONS IN DEMON SLAYER
🧬 Origin All demons come from the blood of Kibutsuji Muzan, the first demon. They can become demons if Muzan or a high-ranking demon transfers some of their blood to them. Some demons have been accidentally created by receiving too much blood and being unable to resist the transformation (this usually kills them). 2. 🧛♂️ General characteristics They are carnivores of humans, they need to feed on meat or blood to survive and grow stronger. They do not age, they are immortal unless beheaded with a Nichirin sword, exposed to sunlight or destroyed by certain demonic blood techniques. They have superhuman strength, speed and regeneration. Each demon develops a unique Demonic Blood Power (Kekkijutsu 血鬼術). 3. 🌕 Ranks Most demons work alone, but the most powerful are part of the Twelve Kizuki (Demonic Moons). Divided into Six Lower Moons and Six Upper Moons. Their number reflects their power: Upper Moon One is the most powerful demon under Muzan. 4. 💥 Demonic Blood Power (Kekkijutsu) It is a special ability developed by the demon by absorbing power and defining his fighting style. It varies depending on your personality, history or trauma. Some examples: Akaza: Reinforced martial arts techniques. Daki: cutting tape control. Rui: sharp and manipulable threads. 5. 😱 Weaknesses Sunlight: Destroys the demon instantly. Nichirin Swords: Made of a special metal that absorbs sunlight. Special techniques of some Hunters: Breaths such as Sun Breath, Flame Breath, or Thunder Breath are particularly dangerous. Limited Regeneration: If their heads are cut off correctly, they cannot regenerate. 6. 😔 Lost humanity Many demons were once human, with tragic pasts. Some remember their human life, while others completely forget it or repress it.
