KNY (New Hashira) Yuko

7. Final Note: "Requiem for the Moon" (Secret/Killer)
   A technique based on silence. Yuki stops breathing and freezes, pointing the flute upward. In complete silence, she sharply makes a perfectly straight vertical cut, and immediately after the swing, she blows into the flute. The sound follows the blade and amplifies the blade's vibration hundreds of times. Upon impact, this vibration travels through the demon's body, destroying its blood vessels from within, even if the external cut was superficial.

1. First Note: "Roy's Symphony" (Concentrated Strike)
   You thrust the blade into the ground and draw a sharp arc, blowing a long note into the hilt's whistle. The sound wave materializes as a ring-shaped shockwave that slices through everything at waist level within a 15-meter radius. Perfect for surrounding areas.

2. Third note: "Glass Dew Tremolo" (Protection)
   By spinning the flute at incredible speed, you create a "cocoon" of high-frequency sound around yourself. Any demon attack that hits this cocoon encounters resistance from the vibrations—the blade literally "gets stuck" in the air, losing momentum. This simultaneously muffles the enemy's hearing, preventing them from hearing your breath.

3. Fifth note: "Echo of Enma" (Deception/Illusion)
   You strike the blade sharply with your cane (like a tuning fork). A piercing dissonance is emitted. At this moment, your image in the demon's eyes "disintegrates" into five silhouettes, moving in different rhythms. The real blow is delivered in the pause between the notes, when the demon thinks the attack is over.

4. Seventh note: "Sonata of the Cleaving Wind" (Long-Range)
   Instead of exhaling through your mouth, you exhale sharply through the side hole of the flute, thrusting the blade forward. This creates an invisible sonic blade—compressed air that slices through targets up to 30 meters away. The impact occurs faster than sound, so the demon only sees the swing but doesn't hear the whistle until the moment of impact.

5. Tenth Note: "Nightmare Conductor" (Mind Control)
   A highly complex technique. By playing low, infrasonic notes near a demon's wound, you cause its blood (or cells) to resonate. This doesn't cause damage, but it causes the demon to hallucinate—it feels like its limbs are moving before it commands them to. It disrupts the rhythm of the fight, causing it to stumble and expose its neck to attack.

The Ubuyashiki Estate in the world of Demon Slayer: Kimetsu no Yaiba is where the leader of the Demon Slayer Corps and his family lived, as well as the Corps' headquarters.
kimetsu-no-yaiba.fandom.com
The estate was located on a mountaintop in a secluded and well-protected location. Its exact location was kept secret to protect it from demonic attacks.
kimetsu-no-yaiba.fandom.com
Important meetings and strategy sessions were held at the estate, particularly in the presence of the hashirō—the Corps' most powerful swordsmen. These gatherings were crucial for planning missions and discussing tactics for combating demons.

Hashira (also known as "pillars") are the strongest swordsmen and the highest-ranking members of the Demon Slayer Organization from the anime Demon Slayer Blade.

The Demon Slayer Corps, the demon slayer organization from the anime "Demon Slayer," has a hierarchical ranking system. Members are divided into 10 ranks (from lowest to highest):
kimetsu-no-yaiba.fandom.com

thegamer.com
vc.ru
Mizunoto → Mizunoe → Kanoto → Kanoe → Tsuchinoto → Tsuchinoe → Hinoto → Hinoe → Kinoto → Kinoe.
kimetsu-no-yaiba.fandom.com
vc.ru
After the final selection, each fighter's rank is inscribed on their hand using a process called the "Wisteria Ornament." To increase their rank, they must complete numerous missions. Mizunoto
The lowest rank is awarded after a person has fully established themselves within the organization. This is the starting rank, after passing the final selection (exam).
kimetsu-no-yaiba.fandom.com
dzen.ru
vk.com
fanfics.me
Mizunoe
The second-highest rank. To advance to it, a slayer must kill at least five common demons. However, Mizunoe still considers slayers to be mere hunters, just one step further on their journey.
vk.com
Kanoto
The third most important rank. Fighters at this rank are already of average class and experience enough to fight at least basic demons, but are not yet good enough to face lower moon demons individually.
vk.com
Canoe
The fourth highest rank. Reaching the rank of Kanoe makes a slayer a highly experienced fighter in the Demon Slayer Corps. They are able to discern the ranks of demons and understand their strength, as well as excel at teamwork.
vk.com
Important: Rank is not an exact indicator of combat prowess—a fighter can achieve a rank despite not having reached a certain level of mastery. For example, Tanjiro Kamado, Zenitsu, and Inosuke start as Mizunoto, but by the start of the Entertainment District arc, they have reached Kanoe through their combined efforts to defeat lower-ranking demons.

It is possible that they were referring to the Nichirin swords from the manga "Demon Slayer".

Gyomei Himejima is a spiked Nichirin flail and battle axe connected by a long, dull grey chain.
The Yoriichi Tsugikuni is a standard-sized Nichirin sword, typically obsidian black in color but bright red in combat. Nichirin swords in the manga and anime "Demon Slayer Sword" (Kimetsu no Yaiba) are specialized blades used by Demon Slayers to slay demons.
kimetsu-no-yaiba.fandom.com
kimetsu-no-yaiba.fandom.com
They are forged from scarlet sand and scarlet ore, found in high mountains like Yoko Sun Mountain. Because Nichirin blades constantly absorb sunlight, decapitating demons with them can permanently kill them.

Zenitsu Agatsuma is a demon slayer and one of the main characters in the anime "Demon Slayer." Appearance: A young man with fair skin, golden-brown eyes that often look downcast, and short yellow hair of varying lengths that turns orange toward the tips. Before becoming a demon slayer, his hair was black. Personality: A coward, he believes that the dangers of being a demon slayer mean he doesn't have long to live. Zenitsu has low self-esteem, which prevents him from living up to the expectations of others and himself. He believes his calling is to live a humble life, not to slay demons. When faced with difficulties or danger, Zenitsu runs away, hides, or simply cries. Respect for Comrades: Even though he is soft, Zenitsu respects his comrades and admires his late teacher, Shihan. His sense of duty to him helps Zenitsu forget his fear and focus at the right moment. Abilities: Acute hearing, allowing him to sense enemy approach, and the ability to fight while unconscious. History: When Zenitsu was younger, he fell in love with a girl who tricked him into collecting money to pay off her debts. She got Zenitsu into trouble, but he was saved by the former Thunder Pillar, Jigoro Kuwajima. To repay him, Zenitsu had to undergo hellish training and become a Demon Slayer. Trivia: Zenitsu has a keen ear for music, allowing him to play the shamisen and koto with great skill. In the parallel universe of Blade Academy, Zenitsu is a high school student and a member of the Morals Committee, despite being reluctant to do so.

Inosuke Hashibira is a character in the anime and manga "Demon Slayer," a demon hunter who travels with Tanjiro Kamado. Appearance: He is usually shirtless, wearing dark blue pants held up by a wide wool belt and matching blue wool socks with bare toes and heels. He wears a light gray boar mask. He has a handsome, feminine face, thin eyebrows, large green eyes with long eyelashes, and shoulder-length black hair that shades to blue. His soft features contrast with his muscular build. Age: 15.
Height: 164 cm.
Weight: 63 kg.
Date of birth: April 22, Taishō era. Biography
Inosuke was abandoned in the forest by his mother as a baby, and was raised by wild boars.
The grandfather of the village boy Takaharu, whom Inosuke often visited from early childhood, taught him human language.
He lived in the forest on the mountain all his life until he went on a journey to become stronger.
He stumbled upon the summit of Mount Fujikasane by chance, where he became a participant in the final selection of demon slayers, becoming the fifth winner.
Following the events of chapters 20–27 of the manga and episodes 11–14, the anime joins the company of Tanjiro Kamado, Zenitsu Agatsuma, and Nezuko Kamado. Character
Hot-tempered and reckless, he often gets into fights with stronger opponents without thinking about the consequences.
He loves to compete and often tries to provoke his comrades into a duel.
He grew up alone in the mountains, which makes it difficult for him to communicate with other people; he cannot read or write, and has trouble remembering names.
He's vengeful, especially when people he cares about suffer. Enhanced sense of touch—due to Inosuke's mountainous upbringing, his sense of touch is phenomenal: he can sense subtle vibrations in the air and even someone's gaze, especially if they're looking at him with hostility.
Poison Resistance - Inosuke was able to resist the effects of the Sixth New Moon's deadly poison, meaning he could develop an immunity to almost all types of toxic substances.

Kakushi (隱) means "hidden." They are not warriors, but a support unit, consisting primarily of people who did not pass the Selection Finals. Their job is to operate unnoticed, appearing after the battle and covering their tracks. The unit is divided into medics (treating and transporting the seriously wounded) and cleaners (cleaning the area and collecting the bodies of fallen swordsmen). They are the ones who retrieve girls from Spider Mountain or evacuate Hashira after the most difficult battles.

Assistants (medical staff)
The true Kakushi stronghold is the Butterfly Mansion, run by Shinobu Kouchou and her assistants. It's not just a hospital, but a top-notch rehabilitation center. It trains young women (Kiyo, Shinobu, Naho, and Kanao Tsuyuri herself) who master complex healing techniques and prepare poisons. Their contribution is crucial: not only do they nurse Tanjiro back to health after the battle with Rui, but they also later conduct a grueling course of functional rehabilitation for him, Inosuke, and Zenitsu, teaching them total breathing and returning them to full fitness.

Unnoticed heroism
They operate at the highest level of risk and with no room for error. The battle in Natagumo Forest demonstrated their professionalism: the Kakushi immediately cordoned off the mountain to prevent civilians from seeing the remains of demons and crippled puppet fighters. During the battle in the Red Lantern Arc, they discreetly evacuate the neighborhood's residents, operating right under Daki's nose. Kagaya Ubuyashiki expresses the utmost respect for them, emphasizing that the Corps' strength rests not on the swordsmen alone, but on those who pick them up after battle. Without the Kakushi and the Butterfly Estate, the hunters' survival rate after encounters with the Moons would drop to zero.

Kyojuro Rengoku (Flame)
Kanjiko the Raven. He screams as loudly and passionately as Rengoku once did. His voice is resonant, his fighting spirit incredible. He endlessly shouts orders and praises with the same inhuman enthusiasm as the late Pillar.

Shinobu Kocho (Insect)
Raven Enju. She speaks in a sweet and hypocritically polite voice, accurately imitating her mistress's hidden rage and passive aggression. Behind the polite facade lies a sharp tongue and strict control over the execution of orders.

Kanae Kouyou (former Flower Hashira)
The only one whose raven was an owl named Ginki (Silver). Extremely calm, she looks upon the world with a disdainful air. She speaks in an old-fashioned, pompous Japanese. Kanae once dreamed of befriending her, but the owl only recently acknowledged her.

Giyu Tomioka (Water)
Kanzaburo the Crow. Old, incredibly insolent, and grumpy. He constantly insults Giyu, calling him "the disgrace of the Pillars," disobeys orders, and pecks out his eyes. Considered the most problematic bird in the organization, he is the walking embodiment of Tomioka's rejection by his entourage.

Sanemi Shinazugawa (Wind)
A rare cream-colored raven with red eyes named Sorai. Just as wild and aggressive as his master. He doesn't convey orders calmly, but rather yells and chatters hysterically, drooling. A perfect reflection of Sanemi's character.

Muichiro Tokito (Mist)
Ginko the Raven. Since his owner is always lost in the clouds and forgets everything, Ginko constantly has to hysterically pull his hair and scream to bring him back to his senses. He speaks harshly and panicked.

Mitsuri Kanroji (Love)
Urukuru the raven. As sweet and fluffy as his owner. He constantly blushes with embarrassment (his feathers bristle), and is very sensitive and shy. He speaks timidly and apologizes often.

Obanai Iguro (Snake)
He doesn't have a raven, but an albino snake named Kaburamaru. He's the smartest and most intelligent "messenger" of them all. He remembers routes perfectly, reads his master's thoughts, and serves as extra eyes without making any unnecessary noise.

Gyomei Himejima (The Rock)
Tenken the Raven, which translates as "sage." Befitting his master, he behaves extremely ascetically, speaks in a religious manner, constantly quotes Buddhist truths, laments the fate of the world, and laments, "Oh, Buddha..."

Tengen Uzui (Sound)
His bird is a trained peregrine falcon, not a raven. It specializes in aerial reconnaissance at high speed. A typical ninja: silent, efficient, and stealthy. Like everything in Uzuya's arsenal, it's ornately decorated.

Appearance: Short dark hair, held back with a butterfly-shaped clip. She wears the standard Demon Slayer uniform: a dark jacket and pants separated by a belt, and white sandals. Over this, she wears a gray haori with a butterfly wing pattern.
dzen.ru
Personality: A calm girl, no matter the situation, she always has a smile on her face. She enjoys teasing others and can sometimes be a little cruel in this regard.
dzen.ru
History: Shinobu was the youngest child of the Kocho family and lived happily with her mother, father, and older sister, Kanae, until her parents were killed by a demon in front of her and her sister.

Abilities and Powers: Despite being the only Hashira who cannot decapitate a demon, her attacks are powerful and deadly, as she was able to seal Douma, Upper Moon 2, into a wall with a single blow.
dzen.ru
Some interesting facts:
Shinobu's sword is engraved with a word that translates to "evil demon."
Her parents worked in the field of combination medicine, so Shinobu is also very talented in the field of medicine.
Shinobu's favorite food is tsukudani with ginger. Shinobu Kocho's motivation for becoming a demon slayer stems from personal revenge for her sister Kanae, who was killed by the demon Douma.
otvet.mail.ru
cerebium.ru
The loss of her sister led Shinobu to a path of revenge, which was reflected in her ruthless and sadistic behavior towards demons.
cerebium.ru
Furthermore, Shinobu and her sister decided to become demon hunters to protect each other and prevent other people from losing what the sisters had lost.

The peculiarity of these crows is that they can speak in full sentences, although their speech is very loud and limited.

Hair: Light, almost silvery-white with a cool turquoise-blue tint. It's styled in an intricate hairstyle: a few strands fall over the face, forming bangs and framing the cheeks, while the bulk of the hair appears to be pulled back into a high ponytail or bun (red ribbons and metal pins/clip-ons are visible at the back of the head).
Eyes: She has heterochromia (different eye colors). Her left eye (facing the viewer) is bright blue, while her right eye is pinkish-red. Her gaze is calm and slightly narrowed. She has expressive, fluffy eyelashes and a hint of pink blush/shadow under her eyes.
Skin: Fair. On the forehead, in the center, is a golden vertical pattern (similar to a diamond or an eye), and on the cheeks are small red marks (in the shape of a heart or a dot). On the right cheek (visible) is a small mole under the eye. The lips are bright pink.

Social Traits: Keeps her distance from everyone, including other Hashir. Doesn't participate in social activities outside of duty. Her presence makes others quieter and more collected.

Clothes and body:

Top: She's wearing a black top with a low neckline (possibly a bandeau). The edges of the neckline are heavily trimmed with fluffy white fur, which extends onto her shoulders.
· Hands: Both hands are covered with long, thick white gloves (or bandages), covering the forearms and wrists.
· Waist and Bottom: A wide white band (belt or corset) with a silver round buckle is visible at the waist. Decorative elements hang down the sides: thick red cords with large round gold coins (or disks) and red tassels at the ends. The hem, visible below, is white, possibly made of lightweight fabric.

Attitude to orders: Follows orders with absolute precision and without comment. Doesn't require explanations or offer advice unless asked.

Yuki was born in a small village on the edge of a forest where, according to family friends, demons lurked and kidnapped people. At 10, Yuki was cheerful and often spent time outside, playing the flute for the village children. But at 12, her life changed when her parents were killed by demons. She was away at the time, which is why she survived. The village men managed to drive away the demon, but Yuki's parents and brother could not be saved. Because of this, Yuki withdrew into herself and became cold to everyone. Yuki promised herself that she would take revenge on all the demons who killed people. At 17, she was found by an older man, a former Hashira, who accepted her as an apprentice. Yuki's talent allowed her to pass the natural selection at 18. At 21, Yuki advanced from the penultimate rank of Demon Slayer to the rank of Hashira, a fact she is very proud of, though she doesn't speak of it.
