Essentially, Blood Demon Arts are blood magic. The abilities and effects granted through Blood Demon Arts can vary greatly. Some can be combat-orientated (i.e. creating dozens of blades) or more supplementary and practical (i.e. controlling a fortress, manifesting illusions).
Gyutaro's Blood Demon Art is extremely powerful and fans witnessed how the members of the Demon Slayer Corps struggled against the Upper Moon 6. It allows him to manipulate his blood into sickle-like shapes that can be used to slice and cut his enemies.
By coating his whips with his blood, he can inject an opponent with his blood when they get damaged.The blood's high potency means that even small dosages would be too much to handle and instead act like a poison to destroy the human body's cells shortly after they enter.
Curse of Kibutsuji
The curse prevents Muzan's name from being spoken aloud, and any who do will meet a horrible demise. One demon, Susamaru, faced this reality when battling Tamayo. Susamaru accidentally shot Muzan's name aloud, attempting to defend his honor with her mind clouded.
The only thing he's weak to is the sun. That is why he turned other humans into demons and spread his blood so that one of them might find a solution against the sunlight, so he can become truly perfect.
Muzan quickly fled the scene, barely still alive, and developed a loathsome fear of the Breath Style Progenitor, prompting him to systematically murder all of the other Sun Breathing users to prevent anyone else like Yoriichi from emerging.
It involves covering a Nichirin Sword with Nezuko Kamado's Exploding Blood to raise its temperature to the point it turns bright red.
Nezuko possesses a unique Blood Demon Art of pyrokinesis, which is unusual for a demon to have such an ability that uses the fire element, as it is lethal to the demons. This might be due to her family coming from the lineage of Sun Breathing users, as they exercised this technique as a ritual dance every year.
Pyrokinesis: Nezuko's Blood Demon Art allows her to generate and manipulate special demonic flames created from her blood that are pinkish in color. Nezuko can do this by igniting her blood or creating it from thin air.
Over a century ago, Doma held the position of Upper Rank Six ( 上 じょう 弦 げん の 陸 ろく , Jōgen no Roku?), and during that tenure, he turned Gyutaro and Daki into demons and introduced them into the Twelve Kizuki.
Blood Demon Art (血鬼術 Kekkijutsu): Technique Deployment (術式展開 Jutsushiki Tenkai): After deploying his technique, Akaza uses his ability to create various shock wave attacks. He can also track his opponents by tracing their bloodlust.
Sleep Inducement: Enmu's Blood Demon Art granted him the ability to force anyone into deep sleep. He can do this through different means, some more subtle than others, but all effectively leaving his foes vulnerable and unable to fight.
Blood Demon Art
Once inside its target, the bullets can immediately grow into a gigantic tree similar to the tree creatures of Upper Rank Four's Zohakuten form and then entangle and wrap around the intended target, paralyzing them.
Black. Toho Co., Ltd. Black is the most mysterious color of all the blades, and is held by the main character, Tanjiro. It is a rare blade and represents the sun; it also holds a theory that the demon slayers who own this sword are not to live a long life.
Tanjiro certainly did a lot of good with his Water Breathing techniques, but his ability to use Sun Breathing both gives him an edge in battle and allows him to stand out among the incredibly powerful Hashira he fights alongside.
Gyomei's Gray Flail and Axe
Undoubtedly the strongest of all of the Hashira in terms of pure strength and power, Gyomei uses weapons that are also very unique.
Fun fact: The reason why Enmu was able to say Muzan's name out loud without dying is because they're married!
So the only reason Muzan is afraid of Tanjiro is because of the Hanafuda earrings he possesses, which acted as a reminder of his downfall. nxt. Hanafuda Earrings are a symbol of Sun Breathing users, traditionally passed down from generation to generation as a family heirloom.
Yoriichi was incredibly proficient in his Sun Breathing, being able to take down demons effortlessly and even overwhelm the Demon King and strongest Upper Rank.
It is revealed that Tamayo's drug had an aging potion mixed in along with the Demon antidote. Due to this, Muzan has aged 9,000 years within the span of three hours.
Being a demon, Muzan is capable of living for many, many years. However, unlike other demons that have aged over hundreds of years. Muzan is well over 1000 years old. Despite achieving an age that no one else has, his appearance makes him look like an adult man in his early to mid-30s.
For those who have watched only the first season of the anime, they will be surprised to know that Muzan turns into a woman in the second season. He keeps transforming in order to hide his true identity, and he's even known to change into an 11-year-old child to hide from Demon slayers.
EnZan is the slash ship between Muzan Kibutsuji and Enmu from the Demon Slayer fandom.
