In particular, is Muichiro related to Kokushibo, the powerful demon who holds the rank of Upper Moon One? And what about Yoriichi, the legendary swordsman who created the first Breathing Style? In this article, we will reveal the shocking truth behind the Demon Slayer family tree and how it affects the story.

Who is Muichiro Tokito?
Muichiro Tokito is one of the Hashira, or Pillars, of the Demon Slayer Corps. He is the Mist Hashira, meaning he specializes in the Mist Breathing Style, a derivative of Wind Breathing. He is a young boy with white hair and purple eyes, and he has a calm and detached personality. He also suffers from memory loss, as he was attacked by a demon when he was a child and lost his older twin brother, Yuichiro.
Muichiro is a prodigy who became a Hashira in less than two months after joining the Demon Slayer Corps. He is also one of the few people who can use a transparent Nichirin Blade, which can change its color depending on the user’s mood or situation. He is very skilled in swordsmanship and can create multiple afterimages of himself to confuse his enemies.
Who is Kokushibo?
Kokushibo is one of the Twelve Kizuki, or Twelve Demon Moons, who serve under Muzan Kibutsuji, the first and most powerful demon. He is Upper Moon One, meaning he is the strongest among them and second only to Muzan himself. He has six eyes on his face, with the kanji for “Upper Moon” and “One” engraved on his middle pair. He also has long black hair with red tips that he ties in a ponytail.
Kokushibo is a ruthless and arrogant demon who looks down on humans and other demons. He is obsessed with strength and seeks to surpass his brother, Yoriichi, who was the strongest Demon Slayer in history. He uses the Moon Breathing Style, which he created by modifying his original Sun Breathing Style. He can also use his Blood Demon Art to manipulate his flesh and blood into various forms, such as blades, wings, or armor.
Who is Yoriichi Tsugikuni?
Yoriichi Tsugikuni was a legendary Demon Slayer who lived during the Sengoku era, nearly 500 years ago. He was the founder of the first Breathing Style, Sun Breathing, which is considered to be the origin of all other Breathing Styles. He was also the wielder of the first Nichirin Blade, which was forged from a scarlet ore that absorbed sunlight. He had red eyes and black hair with red streaks.
Yoriichi was born with a rare condition called “Demon Slayer Mark”, which granted him enhanced physical abilities and senses. He also had another condition called “Transparent World”, which allowed him to see through objects and living beings, including their muscles, bones, blood flow, and even emotions. He was so powerful that he could defeat any demon with a single slash of his sword.
Yoriichi was also a kind and compassionate person who wished to end the conflict between humans and demons. He befriended Muzan when he was still human and tried to cure him of his illness. However, Muzan betrayed him and became a demon, killing Yoriichi’s lover in the process. Yoriichi then dedicated his life to hunting down Muzan and his followers, hoping to find a way to turn them back into humans.
The shocking truth is that Muichiro Tokito is the descendant of Kokushibo, who was originally named Michikatsu Tsugikuni. And Kokushibo was the older twin brother of Yoriichi Tsugikuni. This means that Muichiro is related to both Kokushibo and Yoriichi by blood.
This revelation is made during Muichiro’s battle against Kokushibo in the Infinity Castle arc of the manga. When Kokushibo first sees Muichiro, he feels a sense of familiarity and notices that they have similar physical features and sword skills. He then tells Muichiro that he is his last living descendant and that he inherited his bloodline.
Kokushibo explains that he was once a human named Michikatsu Tsugikuni, who was born as Yoriichi’s twin brother. However, unlike Yoriichi, Michikatsu did not have any special abilities or talents. He was always overshadowed by his brother, who was a genius in everything he did. Michikatsu grew up with a complex of inferiority and envy towards Yoriichi, and he tried to surpass him by becoming a Demon Slayer.
However, even as a Demon Slayer, Michikatsu could not match Yoriichi’s strength or achievements. He also witnessed how Yoriichi was able to befriend demons and humans alike, while he was shunned and feared by both. He felt that his life was meaningless and that he was cursed by fate. He then decided to abandon his humanity and become a demon, hoping to gain more power and freedom.
He changed his name to Kokushibo and joined Muzan’s Twelve Kizuki. He also modified his Sun Breathing Style into Moon Breathing Style, as he rejected the sun that symbolized his brother. He spent centuries killing humans and demons, seeking to become the strongest being in existence. He also tried to find other descendants of his bloodline and turn them into demons, but none of them survived the transformation.
Muichiro is shocked and confused by Kokushibo’s revelation, as he does not remember anything about his past or his family. He also does not understand why Kokushibo became a demon and why he hates Yoriichi so much. He tries to reason with Kokushibo, telling him that he should not be ashamed of being Yoriichi’s brother and that he should respect his legacy. He also tells him that he does not want to become a demon and that he wants to live as a human.
Kokushibo is angered by Muichiro’s words and attacks him with his Moon Breathing Style. He tells Muichiro that he is wasting his potential and that he should join him as a demon. He also tells him that Yoriichi was a hypocrite and a traitor who betrayed his own brother and the Demon Slayer Corps. He claims that Yoriichi was the one who created Muzan and the demons, and that he was responsible for all the suffering in the world.
The two clash with their swords, with Kokushibo having the upper hand due to his superior speed, strength, and experience. However, Muichiro does not give up and continues to fight back with his Mist Breathing Style. He also manages to awaken his own Demon Slayer Mark and Transparent World, which surprise Kokushibo. He realizes that Muichiro has inherited Yoriichi’s abilities and potential, and that he might be able to surpass him someday.
However, before the battle can reach its conclusion, Muichiro is joined by three other Hashira: Gyomei Himejima, the Stone Hashira; Sanemi Shinazugawa, the Wind Hashira; and Genya Shinazugawa, the Demon Slayer who can consume demon flesh and gain their powers. Together, they team up against Kokushibo in an epic showdown that will decide the fate of the Demon Slayer Corps.
What is the outcome of the battle?
The battle between the four Demon Slayers and Kokushibo is one of the most intense and tragic fights in the series. It lasts for several chapters and involves many twists and turns. The four Demon Slayers use their best techniques and strategies to overcome Kokushibo’s overwhelming power and regeneration. They also show their determination, courage, and camaraderie as they fight for their lives and their ideals.
However, they also pay a heavy price for their victory. Muichiro is killed by Kokushibo when he sacrifices himself to cut off one of Kokushibo’s arms. Genya is also killed when he tries to save Sanemi from Kokushibo’s final attack. Sanemi and Gyomei survive, but they suffer severe injuries that leave them unable to fight anymore.
Kokushibo is also defeated by the combined efforts of the four Demon Slayers. He loses both of his arms, one of his legs, and half of his face. He also suffers from internal damage caused by Genya’s bullets infused with Sun Breathing energy. As he lies on the ground dying, he recalls his past memories with Yoriichi and realizes that he was wrong about him. He admits that Yoriichi was a true hero who tried to save everyone from Muzan’s curse. He also regrets becoming a demon and losing his humanity.
He then sees Muichiro’s spirit standing next to him, holding Yuichiro’s hand. Muichiro tells Kokushibo that he forgives him for everything he has done, and that he hopes that they can meet again in another life as a happy family. Kokushibo is moved by Muichiro’s words and feels a sense of peace for the first time in centuries. He then dies with a smile on his face.
