🌲 Mount Sagiri Dense, dark green forest. Light fog almost always. Tall, straight trees. A cold and calm feeling. A traditional Japanese house hidden among the trees. He feels lonely but peaceful. 🌸 Mount Fujikasane Mountain covered with purple flowers (wisteria). The flowers glow softly, almost magically. It's more terrifying at night because there are demons on the loose. The contrast: beautiful flowers + mortal danger. Nice place… if you ignore the fact that they want to kill you. 🚂 Infinity Train Old steam train, black. Interior with red seats and wood. Warm lights inside, dark night outside. When chaos begins, everything becomes dark and twisted. It's elegant until it isn't. 🎭 Entertainment District Streets with red lanterns. Traditional multi-story buildings. Lots of light, bright colors, movement. Festive feeling… but with tension underneath. Brilliant on the outside, dangerous on the inside. 🔨 Blacksmiths' Village Small wooden houses. Surrounded by green mountains. Lots of steam coming out of the forges. Rural, quiet, traditional atmosphere. It sounds like hammers hitting metal all the time. 🏯 Infinite Castle Dark and enormous interior. Corridors that change direction. Floating stairs. Black walls with red details. A feeling that the space has no logic. It's as if gravity decided to take a vacation. 🦋 Butterfly Mansion Large, elegant white house. Large garden with flowers. Clean and calm environment. Plenty of natural light. It's the only place that doesn't seem to want to traumatize you.

She wears a simple but elegant traditional kimono. Calm expression, upright posture. It's like a silent shadow that holds everything up. Strong without needing to raise its voice. 👧👧👧👧👦 Children of Kagaya 👧 Hinaki & Nichika Hinaki Ubuyashiki Nichika Ubuyashiki Twins. Dark hair with straight bangs. Light kimono. Always polite, calm, they speak formally. They convey sweetness… but also a maturity that is rare for their age. 👧 Kuina & Kanata Kuina Ubuyashiki Kanata Ubuyashiki Very similar to their sisters. Serious, elegant, disciplined. They may seem delicate, but they have the blood of leaders. 👦 Kiriya Ubuyashiki Kiriya Ubuyashiki Dark hair. Calm but determined expression. She also wore a traditional kimono. He is the heir. Despite being young, he demonstrates remarkable maturity when it comes to assuming leadership. All Ubuyashiki share something: Calm voice.

They don't shout, they don't boast of strength... but they support the Hashira and the entire Corps.

🗡️ Tanjiro Kamado Appearance: She wears the iconic green and black plaid haori. She has a scar on the left side of her forehead (which changes when she awakens her "Mark") and Hanafuda earrings inherited from her father. Her eyes are large and a warm, dark red.

Although initially he only masters the First Form: Thunder Flash, he has perfected it to such a level that he can perform it in multiple bursts (Six Folds, Eight Folds) or at divine speed. 🐗 Inosuke Hashibira Appearance: He is almost always shirtless, displaying an extremely muscular physique. The most striking feature is his gray boar mask. Beneath the mask, he has a surprisingly feminine and delicate face with large green eyes. His swords are covered in self-inflicted notches.

He has spiky white hair, and his eyes have a perpetually crazed expression. He wears his uniform unbuttoned, revealing his scarred torso. Method of attack: A violent storm.

He has red eye tattoos and silver hair. He wields two giant swords connected by a chain. Style: Tactical and noisy. He uses smoke bombs and gunpowder in conjunction with his swordsmanship.

Her sword has no cutting edge, but a tip designed to inject poison. She always maintains a serene smile. Method of attack: Swift and technical. She is the fastest Hashira in terms of thrusting. Lacking the strength to decapitate, she uses her agility to sting the demon multiple times, injecting lethal doses of glycine poison. Respiration: Insect Respiration. Derived from the flower, it focuses on thrusting movements, jumps, and lunges that mimic the flight and stinging of insects.

🌑 Upper Moon One — Kokushibo Appearance: He wears a purple and black honeycomb-patterned kimono. Most unsettling are his six yellow eyes with red sclera; the upper and lower pairs grant him absolute peripheral and kinetic vision. His hunter mark extends across his neck and forehead. Power: He uses Moon Breathing, a technique that blends high-level swordsmanship with his Blood Technique. His sword, Kyōkukasui, is made from his own flesh and can develop multiple side blades. Detail: He is the older brother of Yoriichi Tsugikuni (the creator of the Breathing Techniques). His envy of his brother's talent led to his demonization, though he retained a twisted sense of samurai honor. 🌕 Upper Moon Two — Dōma Appearance: Platinum blonde hair that appears stained with blood at the crown. He wears a red robe and white trousers. His eyes have a number engraved on a seven-colored iris. He always carries two sharp golden fans. Power: Total control over ice. By fanning, she disperses a fine ice powder that, when inhaled, freezes and destroys the hunters' lungs, stopping their breathing. Detail: He is the leader of the "Eternal Paradise" cult. Unlike other demons, Dōma was born without the capacity to feel empathy or pain, making him a perfect psychopath: his kindness is an empty mask.

. 🔥 Upper Moon Three — Akaza Appearance: Extremely pale skin covered in blue lines that resemble criminal tattoos from the Edo period. He has neon pink hair and golden eyes. His build is that of a pure martial arts athlete. Power: His technique is called Destructive Death. He deploys a compass beneath his feet (Compass Needle) that detects the enemy's "battle spirit," allowing him to anticipate attacks with pinpoint accuracy. Detail: He is the only demon who absolutely refuses to eat or kill women. His obsession with strength stems from a tragic human past where he was unable to protect his loved ones. 🌪️ Upper Moon Four — Hantengu Appearance: In his base form, he is a small, hunchbacked old man with two horns and teary eyes. However, his manifestations (such as Zohakuten) are youthful, imposing, and carry rōmaji drums on their backs. Power: Manifestation of Emotions. Upon being decapitated, his fear is divided into clones: Sekido (Anger/Lightning), Karaku (Pleasure/Wind), Aizetsu (Sadness/Spear) and Urogi (Joy/Sonic Waves). Detail: Hantengu is a pathological liar. Even as a human, he committed crimes and blamed his "hands," genuinely believing himself to be an innocent victim. 🐟 Upper Moon Five — Gyokko Appearance: Its form is the most inhuman. It has no legs, but a body similar to a genie lamp emerging from vases. It has mouths instead of eyes and eyes instead of a forehead and mouth. Small hands grow from its head. Power: Manipulation of water and sea creatures. She can summon carnivorous fish, trap enemies in water prisons, and instantly teleport between her vessels. Detail: He is considered an avant-garde artist. His "art" consists of sewing live human bodies into grotesque shapes for display. He is extremely vain and loses his temper if anyone insults his vases.

🩸 Upper Moon Six — Daki and Gyutaro Appearance: Daki is a deadly beautiful oiran with silver hair and flowers painted on her face. Gyutaro is her opposite: skeletal, with black-stained skin and a dislocated jaw, carrying two bone sickles. Power: Daki controls silk sashes (obi) that act as sentient limbs. Gyutaro uses Flying Blood, blood sickles containing a deadly poison that paralyzes and kills in minutes. Detail: They can only be defeated if both are decapitated simultaneously. Their bond is unbreakable, forged from a childhood of misery and fire in the Entertainment District.

His Zone: The central axis of the Castle. He sits on a floating platform from where he has total control over the architecture. His Job: Space Logistics: With a single strum of his biwa, he can change gravity, move entire rooms, open portals to summon other demons, or expel intruders. Surveillance: He uses independent floating eyeballs to track Demon Slayers throughout Japan and within the castle. Security: His primary function is to keep Muzan hidden and separate the Pillars so they cannot fight together. 🧪 Muzan Kibutsuji — The Core and Scientist Although he is the king, he has a specific work area where he concentrates before the final battle. His Area: The Central Laboratory or "Blood Chamber". An area filled with flasks, test tubes, and living organic matter. His Job: Genetic Research: He works obsessively to find the "Blue Spider Lily" or analyze Nezuko's blood to conquer the sun. Demon Modification: In this area, he alters the cellular structure of his subordinates or creates new Moons (like Kaigaku) ​​through massive blood transfusions. ❄️ Dōma — The Temple of Shadows Dōma not only lives in the castle, but recreates his cult environment within it. His Zone: The Glacial Lotus Pond. An immense, elegant, and icy room, decorated with religious motifs and filled with stagnant water that he can freeze at will. Your Job: Intruder Elimination with Stealth: Your zone is designed to suffocate enemies with its freezing air before they even touch it. Supply of "Devotion": He continues to act as a cult leader, receiving his followers inside the castle (to "save" them, i.e., devour them)

🥋 Akaza — The Combat Pavilion Akaza is not interested in luxuries, only in perfecting his art. Their Zone: The Courtyard of Floating Platforms. An open space, composed of roofs and floors that move, simulating an infinite dojo. His Job: Force Filter: His mission is to intercept the strongest warriors. He does not seek ambushes; his area is clear to allow for pure and brutal close-quarters combat. 🏯 Kokushibo — The Sanctuary of Emptiness The Upper Moon One resides in the deepest and quietest area of ​​the castle. His Area: The Great Hall of the Black Pillars. A room of austere and traditional Japanese architecture that commands absolute respect. His Job: Last Stand: He is the final wall before reaching Muzan. His presence in this area serves as a spiritual pressure that demoralizes anyone who manages to get that far.
