Demon Slayer RPG

This is a secret organization of swordsmen that has existed since ancient times in Japan to protect humanity from demons, led by the demon king Muzan Kibutsuji. They were founded and led by the Ubuyashiki clan, with Kagaya Ubuyashiki as their current leader during the Taisho Era.
The Demon Slayer Corps was founded by the Ubuyashiki clan nearly a thousand years ago. They led the fight against demons and their greatest enemy, Muzan Kibutsuji. Each member of the family would eventually pass the leadership to their descendants because their lineage was cursed. They recruited members from all over Japan, many of whom had been corrupted by demons, to train in the Breathing Style swordsmanship and secretly protect humanity. This constant battle against demons would last until the Taisho era (early 20th century) of Japan, when the main story takes place.
To become a Demon Hunter, one must pass the Final Selection, a deadly test that serves as an entrance exam. The main objective is to survive seven days on a remote mountain teeming with demons.

If the candidate passed, they would receive a uniform and the opportunity to choose the ore for their special (Nichirin) blades to effectively execute demons. They would also obtain a rare species of talking bird called Kasugai Crows to communicate with other Demon Slayers and announce their next mission.

There is a cleanup team within the Demon Slayer Corps known as the Kakushi, most of whose members lack swordsmanship skills. The Kakushi are responsible for providing first aid to injured Demon Slayers after major battles, as well as transporting them to receive proper medical care. A group of Demon Slayers also works as attendants at the Butterfly Mansion, located near the corps' headquarters, to care for and heal injured members.

There are certain families throughout Japan, identified by wisteria flower crests on their homes, who provide food, shelter, and other assistance to the Demon Slaters as a token of gratitude for their work.

Breathing Styles are swordsmanship styles practiced and taught by the Demon Slayer Corps. These styles employ specific, focused breathing techniques, called Total Concentration Breathing, which increase the user's lung capacity and blood oxygenation. This enhances their physical abilities and mental focus, allowing them to fight on par with demons, whose physical prowess far surpasses that of the average human.

Concentrated breathing can also coagulate serious wounds and slow the circulation of poison in the bloodstream. New breathing styles are constantly being created to suit the combat needs of a demon hunter, resulting in the use of new weapons in demon hunting (such as flails and whips). These breathing styles encompass a wider range of concepts, such as animals, plants, and emotions (like snakes, flowers, and love).

All breathing styles currently taught in the Demon Hunter Corps are derived from Solar Breathing, the first ever created.

Demon Hunters have a ranking system, and the known ranks are shown below, from lowest to highest.

Mizunoto → Mizunoe → Kanoto → Kanoe → Tsuchinoto → Tsuchinoe → Hinoto → Hinoe → Kinoto → Kinoe

Hashira; The Hashira (or Pillars in English) are the most powerful swordsmen in the Demon Slayer organization. They are the highest-ranking members of the Corps, second only to the organization's leader.

The Hashira are assigned a specific region of Japan to patrol, generally to gather intelligence on the demons inhabiting that area and hone their swordsmanship. Furthermore, they are only assigned missions if lower-ranking members are unable to complete them. Therefore, their existence sustains the entire organization. To have the opportunity to become a Hashira, a Demon Slayer must eliminate 50 demons, such as Kinoe, or a member of the Twelve Kizuki under Muzan's command (Jūnikizuki).

Regular members;
The average members usually wear black ninja uniforms, each with the symbol 滅 (meaning "kill/destroy/exterminate") on the back, and silver buttons.

Butterfly Mansion;
Some residents who work at the Butterfly Mansion (Sumi Nakahara, Kiyo Terauchi, Naho Takada, and Aoi Kanzaki) wear white robes. Some hashiras (Shinobu and Kanae) and other demon slayers (Kanao) are also affiliated.

Kakushis;
The support members wear similar clothing with most of their head covered by a mask, leaving only their eyes exposed.

Hashiras;
The Pillars can apparently choose their own clothes in a variety of colors, having golden buttons on their uniforms, which mostly match the breathing style they use.

Kagaya Ubuyashiki, known as "The Master" (Oyakata-sama), is the leader of the Pillars and the 97th Commander-in-Chief of the Demon Slayer Corps in Demon Slayer. Though lacking physical strength and suffering from a cursed illness, he guides the Hashira with wisdom, a calming voice, and precognitive abilities.
Role and Respect: It is the fundamental pillar of the Corps, highly respected and loved by all.

Link to Muzan: Kagaya is descended from Muzan Kibutsuji, which causes a genetic curse in his family.
Abilities: She has a voice that brings peace of mind and can predict future events.
Successor: His son Kiriya Ubuyashiki takes over leadership of the Corps. Kagaya is a father figure to the hunters, uniting the Hashira.
Kagaya was a frail-looking man of average height with very pale skin. His black hair reached his shoulders, and he suffered from a family curse that severely affected his health. Much of his skin had a sickly pinkish hue and was wrinkled, and the curse caused blindness, changing the color of his eyes. By the time he appeared at Tanjiro Kamado's trial, his curse already covered a large part of his head, and soon after, it spread throughout his body, leaving him almost completely bandaged and bedridden. Despite his condition, he always wore a kind and calm smile.
Kagaya was strict with his children to prepare them to be Demon Slayers. Despite his strictness, he was kind.
Kagaya had a calm and dedicated demeanor, showing genuine interest in the Demon Slayers, whom he considered his own children. Despite not being a Demon Slayer himself, he handled criticism and visited the fallen. His manner of speaking was kind, persuasive, and considerate.
Kagaya wore a black yukata, a white kimono with flames, and finally, a striped kimono.
Beneath his otherwise kind and gentle demeanor, Kagaya harbored a deep and burning hatred for Muzan Kibutsuji. He saw him as the one responsible for his family's curse, and his anger remained silent.

History and Tragedy:

Blinded since childhood by a fever, Gyomei cared for nine orphans at a temple. His life changed when Kaigaku, one of the children, betrayed the group by leading a demon to them in order to save himself. Despite Gyomei's attempts to protect them, most of the children died, mistrusting his strength. Only young Sayo survived, thanks to him beating the demon with his bare hands until dawn. However, in a state of shock, Sayo accused him of the massacre. Gyomei was sentenced to death, but Kagaya Ubuyashiki rescued him, bringing him into the Demon Slayer Corps.

Physical Appearance:

Standing over two meters tall, he is the tallest, oldest, and most experienced Pillar. His body is muscular, and he bears a horizontal scar on his forehead, a reminder of his battle at the temple. His eyes lack irises due to his blindness and are often filled with tears. He wears the official uniform with a green haori inscribed with Buddhist sutras, red prayer beads around his neck, and always carries a rosary in his hands. In the final battle against Muzan, he loses his left leg.

Personality and Role:

He is a deeply religious, kind, and emotional man who often recites the Amitābha mantra in the face of others' suffering. Due to Kaigaku's betrayal, he developed a cautious nature and doubts the intentions of others until they prove their worth; once he accepts someone, his loyalty is absolute. Because of his wisdom and power, he is the most respected Pillar among his peers and the trusted leader of the Ubuyashiki family.

Past;
Kyojuro was the eldest son of Shinjuro Rengoku. His father was known as the Hashira of the Flame of the Demon Slayer Corps until his unexpected retirement. Kyojuro also had a younger brother who trained alongside him until their father stopped teaching them. Their mother, Ruka Rengoku, passed away after battling an intractable illness sometime after giving birth to Senjuro. His father, on the other hand, became neglectful and abusive, due to a mixture of grief over his wife's death and disillusionment after discovering the existence of Hinokami Kagura and its superiority over all other Breathing Styles. Kyojuro remained close to his brother and helped encourage his pursuit of swordsmanship, even though his brother lacked the natural talent for it.

During his time as a Demon Slayer, he trained an exceptionally strong young woman. Although they were very fond of each other, she hadn't mastered Flame Breathing and opted to use a derivative style known as Love Breathing. He also encountered a demon from the Twelve Kizuki Rank Two: Hairo. The demon mistook him for his father, whom he resented, but Kyojuro, with the help of his protégé, defeated him. For this achievement, he was promoted to a Flame Hashira, like his father, though he reacted with nihilistic apathy.

Tengen Uzui, the Sound Hashira from Demon Slayer, had a traumatic past in a strict Shinobi clan, where he lost most of his siblings. He escaped his father's cruelty and forged a new path, valuing life. He also has three wives.
Tengen was a very tall, powerfully built, muscular man with a slightly tanned complexion. His hair was white and unevenly lengthened, the longest strands reaching his shoulders and styled with three shorter, more prominent strands that arched to fall like bangs between his eyes and on either side of his face. He had very thin, fuchsia-colored eyes that appeared to slant inward, each with a long eyelash that flowed to the other side of his face. During his time in the Demon Slayer Corps, Tengen wore a black uniform with turquoise accents, including hakama pants, white sandals, and gold ornaments on his arms and fingers. He wore a pale gray headband adorned with gemstones and distinctive makeup around his left eye. After retiring due to injuries, Tengen modified his style, wearing a long yukata and a black haori. He replaced his headwrap with a dark patch decorated with gemstones from his former headdress, allowing his hair to fall loosely over his shoulders.

Sanemi Shinazugawa is the current Wind Pillar of the Demon Slayer Corps. He is a 21-year-old man of average height and athletic build, whose appearance reflects the brutality of his profession: his face, chest, and arms are covered in scars that he displays with pride. He has short gray hair and a sharp, eyebrowless gaze that accentuates his aggressive nature. He wears a customized version of the Demon Slayer uniform in dark green, which he keeps open to reveal his torso, along with a white jacket and his Nichirin sword.
His personality is abrasive, impulsive, and stubborn. He is indifferent and rude to almost everyone, except for Kagaya Ubuyashiki, whom he deeply respects. This cold demeanor is a shell he developed after losing almost his entire family to demons. Sanemi harbors a visceral hatred for these creatures, convinced that coexistence is impossible. This led him to viciously attack Nezuko Kamado to try and prove that she couldn't resist human blood, though he ultimately had to accept his leader's will.
Deep down, Sanemi acts out of a distorted brotherly love. His relationship with his younger brother, Genya, is at the core of his emotional conflict. Although he treats him with contempt and tries to keep him away from the demon slayers, his true intention is to protect him from danger so he can live a normal life. After the tragic battle against the Upper Moon One, Kokushibo, where Sanemi loses two fingers and witnesses Genya's death, his heart breaks at not having been able to prevent his last brother's demise.
Finally, after Muzan Kibutsuji's defeat, Sanemi reveals a more human and softened side. He manages to apologize to Nezuko with a tender smile and establishes a more cooperative relationship with Giyu Tomioka, demonstrating that, despite his violent exterior, he possesses a noble and protective spirit.

Shinobu grew up in a loving family dedicated to medicine. Her life changed when a demon killed her parents, leading her to become a demon slayer alongside her sister Kanae. After adopting the orphaned Kanae, Kanae was killed by a demon. Filled with hatred, Shinobu assumed her sister's appearance while concealing her inner rage.
Shinobu was a short girl with fair skin, red lips, and short black hair with purple tips. Her eyes were unusual, a deep purple with no pupils. She wore a yakai-maki bun adorned with a butterfly ornament. Shinobu appeared small and frail, claiming she lacked the strength to decapitate a demon. Her Nichirin sword had a guard shaped like butterfly wings and, while incapable of cutting, was designed to inject wisteria poison. She wore a Hunter uniform consisting of a black and purple jacket and a gray haori with butterfly wings, which had once belonged to her sister.

Mitsuri Kanroji is a key character in Demon Slayer: Kimetsu no Yaiba, known as the Hashira of Love. At 19 years old, she stands out for her unique appearance: a young woman with pale skin and a slender build who hides immense physical strength. Her hair is pink with lime green tips, the result of consuming excessive amounts of sakura mochi, and she wears it styled in three braids.
Her story is marked by a struggle for acceptance. At 17, she was rejected when a marriage proposal came due to her "monstrous" strength and hair color. This led her to dye her hair black and feign weakness to fit in, but she ultimately decided to join the Demon Slayer Corps to find someone stronger than her who would love her just as she is.
As a fighter, Mitsuri is exceptional. She possesses a muscle density eight times greater than that of a normal human, granting her incredible strength and stamina without sacrificing flexibility. Her fighting style, the Breath of Love (derived from her mentor Rengoku's Breath of Flame), utilizes her superhuman agility and a unique Nichirin sword, thin and flexible like a whip, which only she can wield without injury.
Among her feats, her role in the Blacksmith Village stands out, where she faced Zohakuten (the manifestation of the Upper Moon Four), demonstrating reflexes capable of dodging lightning and sonic attacks. During the final battle against Muzan Kibutsuji, she manifested her Huntress Mark and demonstrated her brute strength by tearing off the Demon King's arm with her bare hands.
Her personality is jovial, passionate, and deeply affectionate, always praising her comrades. Her uniform, a personalized gift, and her stockings (a present from Obanai Iguro) reflect her femininity. Although she dies after the battle against Muzan, her story concludes with a promise of eternal love for Obanai, with whom she is reincarnated into a modern and peaceful life.

Obanai Iguro, the Snake Pillar in Demon Slayer, had a difficult childhood. Born into a family of thieves who worshipped a snake demon, he was raised in a cell until the age of 12 as a sacrifice, his mouth mutilated to resemble the demon. His family grew wealthy through theft. When he escaped with the help of his pet snake, Kaburamaru, the demon killed his family, and a surviving cousin blamed him for their deaths. Covering his scars with bandages, he seeks redemption through fighting and finds solace in his love for Mitsuri Kanroji.
Obanai is a short young man with pale skin and a slender, muscular build. He has black hair of varying lengths and almond-shaped eyes with heterochromia: one yellow and the other blue-green, and he is partially blind in his right eye. His mouth is covered with white bandages due to scars on his face inflicted by his family.

He wears the Demon Slayer Corps uniform, which is black in the manga and koamaru-colored in the anime. It consists of a button-down jacket, a white undershirt, and a white belt. He wears a black and white striped haori and wraps his legs in white bandages. He wears zōri sandals with tabi socks and always has his white snake, Kaburamaru, perched on his shoulders.

Muichiro Tokito, the Mist Pillar in Demon Slayer: Kimetsu no Yaiba, had a very tragic childhood marked by the loss of his parents at the age of 10. He was left alone with his twin brother, Yuichiro. After a demon attack where Yuichiro died protecting him, Muichiro, who was injured and suffered from amnesia, became a Demon Slayer at the age of 11 and a Pillar at 14. Both are descendants of Kokushibo, the first Upper Moon, which explains their great talent.
Muichiro is a 160 cm tall teenager with a muscular build and fair skin. He has long, straight, black hair that turns mint blue near his waist. His hair is usually worn loose, with strands framing his face and bangs. His eyes are large and mint blue. He wears the Demon Slayer Corps uniform, featuring turquoise accents and loose-fitting clothing, complemented by tabi socks and zōri.

Before becoming a Demon Slayer, Tanjiro was a charcoal burner before Muzan killed his entire family while his younger sister, Nezuko, became a demon.
Tanjiro has burgundy hair styled back and dark eyes with a visible scar on the upper left side of his forehead. He wears long rectangular earrings with a sun symbol and a black and green checkered haori over the standard Demon Slayer uniform.

She carries a wooden box where Nezuko sleeps during the day, made by Sakonji.

During the final confrontation with Muzan, Muzan wounds Tanjiro in his right eye, poisoning the young man in the process as the wound rapidly becomes infected, growing into a grotesque, tumor-like mass of flesh that severely injures Tanjiro, causing him to lose his right eye. Later in the fight, Muzan tears off his left arm.

Tanjiro is a kind and determined person, especially in his quest to find a cure for his sister Nezuko. Although strong, he doesn't hesitate to ask for help and is very protective of his friends and his sister. He has a great capacity for empathy, which makes him hesitant when facing demons. However, he also hides a dark side that emerges when his tolerance is exhausted, causing him to become aggressive, especially towards demons who cause suffering. He sees himself as honorable and has trouble lying. Over time, he has learned to be more calculating and ruthless when facing his enemies.
