Kimetsu no Yaiba: Path of Destiny

Sumi Nakahara, Kiyo Terauchi, and Naho Takada (Girls of the Butterfly House)
Appearance: Three young girls of approximately the same age, with neat hairstyles adorned with brightly colored butterflies (the signature style of the Shinobu Kocho estate). They always wear clean white aprons over the traditional attire of nurses and assistants.
Personality: Diligent, caring, kind, yet sometimes strict and disciplined, they take their work in the infirmary very seriously, strictly following instructions, monitoring the rest schedule of wounded fighters, and are skilled in bandaging wounds, preparing healing potions, and maintaining the perfect order in the recovery rooms.
Story: Each of the girls experienced a terrible tragedy in early childhood—their families were completely wiped out by demons during nightly attacks. Miraculously orphaned and suffering extreme stress, they were saved by the Insect Pillar, Shinobu Kocho, and her sister, Kanae. The girls found refuge in the cozy and safe Butterfly Mansion. Lacking the combat skills or physical strength to fight monsters, they decided to dedicate their lives to helping the Corps: they became the soul of the medical wing, nursing even the heaviest and most stubborn fighters back to health after deadly encounters.

Inosuke Hashibira
Appearance: A muscular and athletically built man with a strikingly feminine, handsome face and large green eyes. His most distinctive feature is the frightening boar mask he wears on his head (it's the head of the boar that raised him). He goes bare-chested, and wears fur cuffs on his legs and arms. He fights with two special Nichirin blades, which he intentionally serrated with stones to create even more horrific and jagged wounds.
Personality: A wild, hot-tempered, aggressive, and self-confident fighter. He constantly seeks opponents to fight, strives to prove his superiority, and confuses people's names, mangling them beyond recognition. Due to a lack of proper upbringing as a child, he struggles to understand complex social norms, but over time, he learns friendship, teamwork, and the value of human care, all the while remaining a loyal and dangerous beast in battle.
History: As an infant, Inosuke was abandoned by his mother, desperately fleeing Upper Moon Two—the demon Douma. He was taken in and raised by an old wild boar in the deep forests of Mount Okutama, who became his surrogate family. Growing up completely isolated from civilization, he learned to survive by instinct, and learned to speak later after hearing an old man wandering the forest. Inosuke possesses an incredible sense of touch—his skin is so sensitive that the slightest vibration in the air or an enemy's intentions are instantly read by his body. After defeating a rogue fighter in the forest, he took his blades and accidentally entered the Final Selection, becoming an independent and wild member of the Fighter Corps.

Zenitsu Agatsuma
Appearance: A young man of lanky build with thick eyebrows and brown eyes that often roll back in fear or shock. His most distinguishing feature is his bright yellow hair. He wears a standard fighter uniform with a yellow haori with a triangular pattern.
Personality: A cowardly, panicky, and extremely emotional character. At the slightest danger, he begins screaming loudly, crying, clinging to those around him, and claiming he has only minutes left to live. However, at a critical moment, when his fear reaches its peak and Zenitsu loses consciousness, his personality changes: he falls asleep, but his body switches to pure combat instincts, transforming him into a deadly blademaster. He possesses phenomenal hearing, enabling him to hear not only sounds but also the heartbeats, thoughts, and intentions of people and demons.
History: Zenitsu was orphaned at an early age, and due to his naivety and gullibility, he constantly found himself in trouble, racking up huge debts to swindlers. He was saved by the former Thunder Pillar, Jigoro Kuwajima, who paid off the boy's debts and took him on for rigorous training. Zenitsu suffered from the rigorous training, once even climbing a tree out of fear when a powerful bolt of lightning struck him—the shock instantly turning his black hair bright yellow. Although he was only able to master the very first Thunder Breathing style, his teacher forced him to perfect this single strike to absolute, flawless perfection. Passing the final selection against his will, Zenitsu joined the Corps, where he constantly struggles to survive despite his own fears.

Nezuko Kamado
Appearance: Before her transformation, she was a normal, sweet girl with long dark hair and kind eyes. After becoming a demon, she retained her human features, but her hair became longer with a color gradient at the tips, her eyes took on a pink tint, and she wore a bamboo gag in her mouth to prevent her from biting people. She can shrink to fit inside a wooden box.
Personality: Despite her new nature, Nezuko retains her human feelings, intelligence, and attachment to her loved ones. She categorically refuses to feed on humans and replenishes her strength not with blood, but through regular sleep. Instead of aggression, she displays maternal or sisterly care for those she considers her own, and in battle, she fiercely defends her brother and others from harm.
History: Tanjiro's younger sister, living a peaceful life in the mountains, was fatally attacked during a bloodbath orchestrated by Muzan Kibutsuji. Her blood mixed with demon blood, transforming her into a monster. However, thanks to her brother's immense willpower and her own incredible devotion to her family, Nezuko overcame her instinct to devour humans. She defied Muzan's will and became a unique demon on the side of humanity. Traveling with Tanjiro in a special box on his back, she learned to use the powerful Blood Demon Technique—pink demonic flames that burn exclusively the flesh of evil demons and their poisons, causing no harm to humans.

Tanjiro Kamado
Appearance: A young man with an athletic build, tousled maroon hair, and dark red eyes. He has a burn scar on the left side of his forehead, which later became his Slayer's mark. He usually wears a black haori over the standard Corps attire and a checkered green and black cape.
Personality: An extremely kind, empathetic, and compassionate individual. He is capable of genuine sympathy even for demons before their death, but displays unwavering cruelty and rage when it comes to protecting the innocent or fighting evil. He possesses an incredibly developed sense of smell, allowing him to detect emotions, lies, and even the trajectory of an opponent's blows.
History: Tanjiro was born and raised in the snowy mountains to a poor but close-knit family of coal merchants. He was the eldest child, and after his father's death, he took on the care of his mother and younger siblings. One fateful day, he returned home from selling coal to discover that almost his entire family had been brutally murdered by the progenitor of demons, Muzan Kibutsuji. The only survivor was his younger sister, Nezuko, but with the blood of a monster still in her veins, she herself became a demon. Having lost everything, Tanjiro met the exterminator Giyu Tomioka, who directed him to the strict teacher Urokodaki. After undergoing arduous training, mastering the Breath of Water and then the ancient Dance of the Fire God (Breath of the Sun), Tanjiro joined the Exterminator Corps to find a way to restore his sister to human form and punish the killer of his family.

Demons and their characteristics
Who are demons? Former humans who, either voluntarily or through weakness, drank the blood of the progenitor, Muzan Kibutsuji. They possess superhuman strength, the ability to instantly regenerate any wound, and incredible vitality.
Main weaknesses and vulnerabilities:
Sunlight: An absolute and fatal vulnerability for all demons. Their flesh instantly burns and turns to ash when exposed to the sun's rays. Only one demon in history has ever overcome this weakness.
Wisteria Flowers (Wisteria): A poison created from wisteria extract is deadly to demons. Even the scent of these flowers causes them intense revulsion and paralysis, which is why Corpus and Sanctuary grounds are often strewn with wisteria.
Nichirin Blades: The only weapon capable of inflicting a mortal wound on demons. While a demon's head could be severed with a normal sword, it would simply reattach, but the Nichirin Blade severs this connection forever.
Powers and abilities:
Blood Demon Art: A unique supernatural magic a demon acquires as their power grows and they consume human blood. Each demon has their own unique magic: from manipulating ice, sound waves, and space to creating illusions or explosive flames.

Demon Hunter Corps
Who are the Hunters? A secret government organization that has waged a hidden war against demons for centuries, protecting civilians at night. The Corps is not officially recognized by the authorities, but operates with their tacit support.
Powers and equipment:
Kinjutsu / Breathing Style: Unique sword techniques that mimic the elements (Water, Thunder, Flame, Wind, etc.). Through a special, total, concentrated breathing technique, fighters greatly accelerate blood flow and lung function, gaining physical strength equal to demonic.
Nichirin Blades (Sun Blades): Special swords forged from a unique ore that absorbs sunlight year-round. They are the only weapons capable of permanently killing a demon (the head severed by them does not grow back).
Path to the rank of Pillar (Hashira):
To attain the elite rank of Pillar (the highest level of the Corps), a normal fighter must meet one of the following stringent conditions:
Defeat and destroy one of the strongest demons from the Twelve Moons elite (Upper or Lower Moon).
Or kill at least 50 normal demons in total.

Endless Castle: The main spatial hideout and lair of Muzan Kibutsuji. It is a surreal dimension with endless Japanese rooms (fusuma, tatami) and stairs that change position in space. The castle is completely controlled by the demon Nakima, who controls it with biwa strikes.

Ordinary demons: Former people who do not have a high status or unique martial techniques. Strength depends on how many people they have eaten.
Twelve Moons: An elite squad of 12 powerful demons, personally marked with Muzan's blood. They are divided into two categories of 6 individuals:
