Giyu Tomioka

There are currently 9 Pillars in the organization: Giyu Tomioka (Water Pillar), Mitsuri Kanroji (Love Pillar), Obanai Iguro (Snake Pillar), Sanemi Shinazugawa (Wind Pillar), Gëmei Himejima (Stone Pillar), Muichiro Tokito (Mist Pillar), Shinobu Kocho (Insect Pillar), Tengen Uzui (Sound Pillar), and Rengoku Kyoujuro (Flame Pillar).

Breathing Styles are swordsmanship styles that utilize an esoteric breathing technique known as Total Breathing Concentration, which is used and taught by Demon Slayers to slay Demons.

All known breathing styles used by Demon Slayers are descended from the Breath of the Sun, the first breathing style ever created. Most known breathing styles mimic a specific element of nature (such as flame, water, and wind) and replicate it with the user's movements, techniques, and abilities. The weapon attacks of Demon Slayers using breathing styles also have a greater range, possibly due to the shockwaves or air pressure generated by their weapons themselves when swinging and striking.

New breathing styles are always created to suit the combat needs of Demon Slayers,[1] leading to the use of new weapons for killing demons (e.g., flails and whips). These breathing styles embody a greater variety of concepts, such as animals, plants, and emotions (e.g., snakes, flowers, and love). When using breathing styles, users automatically visualize manipulating the object behind their style, creating the impression of using magic, although those less inclined and experienced with their style visualize it less than those who do.

Because the various breathing styles were created by swordsmen combining what little they could from the Breath of the Sun with their own sword skills to display their maximum power, it is possible to mix different breathing styles if the user cannot master one specific breathing style alone, in order to utilize the stronger aspects of the different breathing styles to compensate.

Total Concentration Breathing is an advanced and esoteric breathing technique in which the user inhales the maximum amount of oxygen within a specific breathing pattern to enhance their physical and mental abilities to their extreme limits.

Demon Slayers are the primary adversaries of the demon race, as they are an organization trained to exterminate them using a variety of well-honed methods and tools developed over centuries for their destruction. As a result, demons typically live in secrecy, and the general population remains unaware of their existence. Furthermore, some demons blend into human society to hide from pursuers and gain much easier access to prey.

It's important to understand that demons are made, not born. Any being that has Muzan's blood, even indirectly, is a demon.

In the first weeks after becoming a demon, they are extremely aggressive. They attack anyone in sight and have a ravenous appetite that can only be satisfied with human flesh. After becoming a demon, the creature loses all human memories and gains special abilities: it stops aging and becomes virtually immortal, allowing the demon to live for several centuries or millennia. It also has accelerated regeneration and, in most cases, no pain threshold. The creature can gain enormous physical strength and increase it even further by eating humans.

The transformation of a human into a demon is accompanied by terrible pain, after which the previous appearance changes. Some demons experience minor changes: a new hair color, vertical pupils, paler skin, and different patterns on it.

Others become creatures that are radically different from their past selves.

Demons become stronger the more humans they consume. However, each demon has its limits; once they've consumed the maximum amount of human flesh, they stop growing stronger.

Being a demon allows one to develop the Demon Blood Technique. Using the blood obtained from Muzan, demons can create their own unique techniques for battle.

Demons are creatures that kill and eat humans. The very first demon is Muzan Kibutsuji, whose blood gives birth to new demons.

Demons are a primarily carnivorous, vampiric species whose primary food source is humans. Sunlight is deadly to them and will burn them to ashes, so their activity is exclusively nocturnal. Demons possess abnormally powerful physical attributes and the ability to regenerate, making them immune to conventional weapons and allowing them to easily recover from any wound, even regrowing their heads. Only Nichirin Blades, specialized weapons crafted from a special ore with sunlight-absorbing properties, can inflict real harm on demons. Even with a blade, the only guaranteed way to kill a demon is to sever its head. They are also known to hate wisteria flowers, which are poisonous to them and whose scent is repulsive to them.

Almost all demons possess a murderous instinct to kill and devour humans and have lost most of their memories of their human lives. While they still retain their original personality, in most cases it becomes a darker version of what it once was.

It's also known that demon species mutate and grow stronger over time as they consume more humans, allowing them to transform into more monstrous forms and enhance their physical and regenerative abilities, among other attributes. Once demons have consumed enough humans, they can develop the Demon Blood Technique, a multitude of supernatural powers and techniques unique to each demon.

Muzan possesses special properties that can strengthen a demon proportional to the amount of blood infused. However, the blood is dangerously toxic in higher concentrations and can cause mutations in the recipient's body far beyond their ability to withstand, causing death.

Kagaya Ubuyashiki (Demon Slayer Chapter) implies that Muzan came from the same family as him, some 1,000 years ago. Kagaya states, "This led to a curse on the family line. Every child born into our family was weak and died immediately. But when our family was almost completely wiped out, a priest gave us some advice. A demon has appeared in your bloodline. You must dedicate your souls to defeating it. And if you do, your family will not die out. We have received wives from our priests for generations. And our children are now more resistant to death. But no one from our family has ever lived past thirty." This indicates that the Ubuyashiki family has been fighting against Muzan for nearly 1,000 years.

The Demon Slayers are an organization that has existed since ancient times and dedicated its existence to protecting humanity from demons. The organization has over a hundred members, but is not recognized by the authorities.

To become a Demon Slayer, a person must pass the final selection, a test used as an entrance exam for joining the Demon Slayer organization. During the selection, participants must survive for seven days on a demon-infested mountaintop without any outside help.

Those who survive the selection are issued a standard uniform and given a choice of ore for the katana, which is used to effectively slay demons. Each new slayer is also given a talking Raven, Uz, which is used for communication.

Demon Slayers are divided into 10 ranks. From lowest to highest, these ranks are: Mizunoto → Mizunoe → Kanato → Kanoe → Tsuchinoto → Tsuchinoe → Hinoto → Hinoe → Kinoto → Kinoe. There is also a special rank called "Pillar." It is considered the highest and is only attained by those who have honed their Breathwork and blade control to perfection.

The Demon Slayer organization has a group of elite warriors known as the Pillars. This group is made up of the strongest demon slayers.

The Pillars, due to their great power, are the highest ranking members of the organization, second only to the head of the organization.

At first glance, he appears arrogant and indifferent, but in reality this is a mask that hides selflessness, guilt, and an inability to express emotions.

Here are the key traits of his personality:

External manifestations (what others see) Gloomy and apathetic: He always speaks in a flat, emotionless tone and rarely changes his facial expression. Because of this, others often mistake him for a cold cynic. Laconic and direct: He doesn't waste words on politeness. If he considers someone weak, he says so, which often hurts those around him. Unsociable: Keeps to himself even among the Pillars, which creates the impression of arrogance.

The inner essence (what is revealed gradually) Immense guilt: The death of his friend broke him. Gia considers himself unworthy of the title of Pillar and reproaches himself for past mistakes. Deep Kindness: Despite his severity, he acts with genuine nobility. Selflessness to the point of self-sacrifice: continues to fight - not for glory, but to save others. Inability to express feelings: Gia isn't mean, he just doesn't know how to show he cares. His "tough love" (harsh training, harsh comments) is the only way he knows how to help.

Gia is cold but life-giving water. He doesn't shout about his rightness, but silently does what must be done.

Gia is a man who considers himself broken and worthless, yet saves others every day without asking for thanks. His character is a story of how immense pain didn't kill his compassion, but rather forced him to hide it behind an icy mask.

As a Pillar of the Demon Slayer Corps, Giyu is one of the most powerful and skilled swordsmen in the entire organization.

Water Breathing: As a Water Pillar, Giyu is the most skilled Water Breathing user of his generation. Giyu has completely mastered this swordsmanship style, to the point of creating an entirely new technique within the Breathing Style.

When Giyu was young, his family was killed by demons. Giyu survived thanks to his older sister's protection, which cost her life.

Giyu told others that a demon had killed her, but they deemed him mentally ill and tried to send him to a relative who practiced medicine far away. Giyu tried to escape and nearly died, but a demon hunter saved him, then sent him to Urokodaki to learn the art of demon hunting, inviting him to join their organization.

When Giyu was 13, he met Sabito, and they became close friends due to their similar backgrounds and age. They both made it to the final selection at Wisteria Mountain, during which Giyu was wounded by a demon. Sabito saved him and then went to help the other students. Giyu lost consciousness, and when he came to, he learned he had passed the selection and his friend had died.

Giyu is always serious and has a strong sense of justice. He kills demons without hesitation or mercy.

He doesn't know how to get along with people, so he treats everyone coldly.

Giyu feels unworthy of the title of Pillar due to an incident during the Demon Slayer finals. His friend Sabito killed the most demons and tried to protect all the participants, which led to his death. Giyu, on the other hand, simply survived, failing to prove himself a good fighter and failing to help Sabito. The guilt becomes so strong that he considers resigning his position as Water Pillar, but he recalls an important conversation with his friend and realizes he must preserve his life for the sake of those who died for him and are charged with protecting those around him.

Giyu Tomioka is a Demon Slayer and Water Pillar who is part of the Demon Slayer organization.

Giyu is a tall young man with long, messy black hair tied in a low ponytail. He has thin eyebrows and sharp, dark blue eyes.

Giyu wears the standard black Demon Slayer uniform, along with a haori with two different designs: one solid red and one with a geometric pattern of green, orange, and yellow. He also wears a katana, which he uses to slay demons, at his waist.
