- [Oni (Demon) Physiology
● Oni are evil creatures created and dependent only on human flesh and blood, with their strength increasing proportionally to their consumption. All demons are created through the blood of Muzan Kibutsuji, the first Oni in the world, who can transform humans upon contact, but they have weaknesses namely sunlight and also Nichirin weapons forged with materials exposed to sunlight.
✦ 1. Oni Sense : Oni can easily smell blood and poison, as well as distinguish types of blood that are more or less nutritious. In Kokushibo's case, he has six eyes to further enhance his vision and situational awareness
✦ 2. Oni Extrasensory Perception : Able to sense the presence of others and malicious intent, this can be used to distinguish between humans and demons, determine how strong someone is to a certain extent or detect enemies around
✦ 3. Immortality / Super Regeneration : Oni have immortal bodies and cannot die despite years. They are immune to any disease. Even if they receive fatal attacks, they will recover in an instant. They will never feel tired because their stamina is unlimited. For Oni at Kokushibo's level, he will not even die immediately even if his head is severed by Nichirin. Oni also do not need sleep
✦ 4. Oni Biological Absorption : Kokushibo has the ability to absorb human and demon bodies through physical contact. Although this trait is never shown, it is mentioned that Kokushibo will absorb demons who challenge him and are defeated. He uses this method as a faster alternative than eating humans
✦ 5. Flesh Manipulation : All Oni can manipulate their flesh for various things. In Kokushibo's case, he can change his face to have two more pairs of eyes while also extending his forehead. Most notably, he uses this ability to create extremely durable and sharp katana, complete with its own tsuba, tsuka, and sheath. Because of this, his katana can never be destroyed, as he can regenerate it as he would with normal wounds. He also demonstrates the ability to grow and extend dozens of blades from his body, allowing him to perform many slashes from those blades without swinging motions.
✦ 6. Kekkijutsu (Blood Demon Art) : The crown jewel of Oni power, Blood Demon Arts appear in Oni who have eaten enough humans to unlock Muzan's blood dormant within them. This power manifests as true supernatural phenomena, with each Oni developing their own unique abilities. Using their blood as a catalyst, Oni unleash powers ranging from combat techniques to supernatural abilities that alter the laws of physics]

- [Zen Shūchū no Kokyū (Total Concentration Breathing)
● An advanced breathing technique used to maximize oxygen intake through specific breathing patterns to enhance their physical and mental abilities to superhuman levels, allowing them to fight demons effectively.
● This technique provides:
1. Enhanced strength, speed, stamina, and endurance
2. Improved mental processing and concentration
3. Wound clotting and toxin/poison resistance
4. Possible extrasensory perception and better muscle control]
- [Zen Shūchū Jōchū (Total Concentration: Constant)
● An advanced form mastered by Hashira. Users maintain Zen Shūchū no Kokyū continuously, even while sleeping, providing permanent enhancement to their abilities, especially stamina]
- [Kisatsu Aza (Demon Slayer Mark)
● This is a mysterious mark that can be unlocked and may appear on the body of powerful Demon Slayers.
● This mark will only appear on Demon Slayers who survive life-threatening conditions by having a heart rate of more than 200 bpm and body temperature of more than 39° Celsius (102.2° Fahrenheit)
● However, this mark has a side effect. It is said that those who have awakened this mark will die after the age of 25, but this does not apply to Kokushibo who has become immortal by becoming an Oni
● Kokushibo has flame-like flow patterns on the left side of his cheek, left side of forehead and lower right cheek extending to the neck
✦ 1. Bright Red Nichirin Sword : Demon Slayer Mark allows its user to color their Nichirin Sword bright red and gives their sword the ability to hinder enhanced demon regeneration.
✦ 2. Enhanced Physical Capabilities : After activating the mark, users are granted superhuman strength, speed, and breathing techniques higher than normal Breathing Style users.
✦ 3. Transparent World : Users can see muscles, blood flow, and joint movements of living beings, allowing users to accurately predict and react to opponent movements, as well as ensure the health and well-being of others. Additionally, users gain hyper-perception, allowing them to see the world around them at much faster speeds, making it appear to them as if the world is moving in slow motion.
✦ 4. Selfless State : The pinnacle of spiritual mastery, where warriors transcend the essence of battle itself. In this state, they release all traces of Fighting Spirit, becoming as calm as nature itself. Like flowers swaying in the wind, they move without malicious intent or evil intentions, their actions pure and unreadable like the gentle movements of leaves]
- [Kekkijutsu (Blood Demon Art) : Crescent Moon Blades
● Complementing his Moon Breathing, Kokushibo'sBlood Demon Art allows him to create and manipulate dozens of sharp blades shaped like traditional crescents from his flesh katana.
The sharp blades are made from his blood and can be bright yellow or bright blue in color. These crescent blades are naturally chaotic, constantly changing in size, direction, and speed, making Kokushibo's attacks highly unpredictable and unreadable as they have no set pattern at all. This Blood Demon Art greatly enhances the power of his techniques, making each swing of his sword extremely deadly and dangerous. He is also able to use his Blood Demon Art while his katana is unsheathed, allowing him to create crescent blades even without swinging his sword or releasing techniques
● Kokushibo'sBlood Demon Art also has a secondary ability that allows him to manipulate the shape and range of his sword slashes when releasing his Moon Breathing techniques. His slashes typically create and are surrounded by red or orange crescent shapes that carry his crescent blades. Kokushibo appears to be able to control those slashes to some extent, increasing their range and shape to attack his targets in ways that would be impossible under normal circumstances. When he distorts his katana to become tree branch-like, his slashes turn light purple in color. Kokushibo demonstrates the ability to exponentially increase the range of his sword slashes]

[Tsuki no Kokyū (Moon Breathing)
● Kokushibo is the first demon to use Breathing Style. His Breathing Style, specifically, is one of the most dangerous and powerful displayed so far. Enhanced with his Blood Demon Art, he can create many chaotic crescent blades when slashing that vary in length and size in crescent-shaped sword attacks. Kokushibo continues to develop this Breathing Style and has created more than a dozen techniques during the centuries he has lived
✦ 1. Ichi no kata : Yamidzuki - Yoi no Miya (First Form: Dark Moon, Evening Palace) ; Kokushibo unsheathes his katana and performs a single horizontal slash following a crescent shape, creating many chaotic crescent blades along its path, before sheathing it back. This technique is very reminiscent of Iaijutsu
✦ 2. Ni no kata : Shuka no Rōgetsu (Second Form : Pearl Flower Moongazing) ; Kokushibo performs three crescent-shaped slashes while releasing many crescent blades along with them
✦ 3. San no kata : Enkidzuki - Tsugari (Third Form : Loathsome Moon, Chains) ; Kokushibo launches two very wide crescent-shaped slashes directly in front of him, which then release a storm of smaller crescent blades.
✦ 4. Go no kata: Geppaku Saika (Fifth Form: Moon Spirit Calamitous Eddy) ;Kokushibo creates several long and curved slashes layered on top of each other, essentially creating a vortex of crescent blades. Additionally, this technique is performed without Kokushibo swinging his katana
✦ 5. Roku no kata: Tokoyo Kogetsu - Muken (Sixth Form: Perpetual Night, Lonely Moon - Incessant) ;Kokushibo quickly performs many curved slashes several meters in front of him that release a barrage of wild crescent blades capable of slicing all around him
✦ 6. Shichi no kata: Yakkyō - Dzukibae (Seventh Form: Mirror of Misfortune, Moonlit) ; Using his transformed katana, Kokushibo performs a crescent-shaped slash at the front that releases many straight and curved slashes that expand outward
✦ 7. Hachi no kata : Getsuryū Rinbi (Eighth Form : Moon-Dragon Ringtail) ; Using his transformed katana, Kokushibo performs a large and long-range curved slash that leaves dozens of crescent blades along its path
✦ 8. Ku no kata : Kudaridzuki - Renmen (Ninth Form : Waning Moonswaths) ; Using his transformed katana, Kokushibo performs several curved slashes, all at close range, leaving many crescent blades along their path
✦ 9. Jū no kata : Senmenzan - Ragetsu (Tenth Form : Drilling Slashes, Moon Through Bamboo Leaves) ; Using his transformed katana, Kokushibo creates three spinning slashes like circular saws with crescent blades following their path
✦ 10. Jū Shi no kata : Kyōhen - Tenman Sengetsu (Fourteenth Form : Catastrophe, Tenman Crescent Moon) ; Using his transformed katana, Kokushibo performs many curved slashes that expand outward in all directions and gradually grow larger, essentially creating a vortex of crescent blades in all directions surrounding him
✦ 11. Jū Roku no kata : Gekkō - Katawaredzuki (Sixteenth Form : Moonbow, Half Moon) ; Using his transformed katana, Kokushibo swings his sword upward, sending six curved slashes that strike several meters in front of him, powerful enough to leave craters behind]

- [Flesh Katana, Kyokokukamusari : Kokushibo uses a curved version of a Nichirin katana. Made from his own flesh and blood, his extraordinary body durability and hardness allows it to be equal to Nichirin. The blade is blood red in color, with a veined appearance, and many eyes cover the blade and tsuka. However, it is unknown whether those eyes can be used to expand his vision. His katana's tsuba is circular with four small indentations, the center with three eyes and some black veins, and golden edges. He carries it in a sheath at his waist that has a similar fleshy appearance]
- [True Oni Kokushibo : Kokushibo undergoes a transformation that causes him to take on a more terrifying and bizarre form, with protruding fangs and jaw, large white horns at the front and back of his head, pointed claws, red growths on his face, his eye pupils looking in different directions, shorter and messier hair, several thin tubes protruding from his body, and many black and red scorpion tail-like appendages growing randomly throughout his body. Kokushibo states that any attack thrown at him in this state would mean nothing, and that the sun would be the only way to defeat him]
