In this post, we are going to talk about who killed Genya in Demon Slayer: Kimetsu no Yaiba. Demon Slayer is getting more and more popular, and it could end up being one of the most popular animes ever. Since it came out, fans all over the world have been enthralled by its sad story about humans and demons. It has a lot of exciting sword fights, cool special moves, and engaging animations.
Genya is one of the unique Demon Slayers belonging to the Demon Slayer Corps. He has the ability to eat demon flesh and gain their powers. Along with that, Genya is the younger brother of Sanemi, the Wind Hashira.
Who Killed Genya / How Did Genya Die?
Kokushibo, the Upper Moon Rank One, drives Genya almost to death. This battle takes place in Infinity Castle Arc. But, Genya dies due to consuming a lot of flesh from Kokushibo and then getting the weakness of Demons. Thus, during sunrise, his body faded away.
One of the most intense battles in Demon Slayer is a battle that takes place in the Infinity Castle, occurs between Demon Slayer Genya Shinazugawa and three Hashira, Muichiro Tokito, Sanemi Shinazugawa and Gyomei Himejima against Upper Rank One Kokushibo.
Kokushibo Gives The First Hit
Genya hides behind a curtain with a Nichirin Sword and his western-style double-barreled shotgun. Kokushibo was right behind Genya when he was about to pull the trigger. He asked Genya if he agreed or not. Genya’s arm with the shotgun falls off when he does this, and Muichiro screams his name as loud as he can.
Genya quickly pulls the Nichirin Sword from his back, but it doesn’t help because Kokushibo cuts off his last arm cleanly.
Kokushibo looks at Genya’s cell structure and realises that he is a Demon Slayer who doesn’t use a Breathing Style. Instead, he gets his strength from eating demons, which gives him the same ability to heal as a Breathing Style user.
Kokushibo Knows Genya’s Abilities
With no hesitation, Kokushibo purposefully cuts Genya’s torso in half, with Muichiro understanding that he will Genya this way.
He is shocked that Genya is not dead from his injuries even though he specially went to kill him. He says that three hundred years ago, he met a Demon Slayer who consumed Demons like Genya and killed him by cutting his torso. Kokushibo tries to cut off Genya’s head because he knows that every Demon Slayer who eats Demons must have a weak spot.
Genya’s brother, Sanemi saves him when he uses the Wind Breathing, Fourth Form: Rising Dust Storm, to block the Upper Rank’s attack.
Genya and Sanemi
Sanemi tells Genya that he shouldn’t have joined the Demon Slayer Corps. Instead, he should have gotten married, had kids, and promised to protect them, she says. This makes Genya cry as Sanemi tells him how he really feels about him. When Kokushibo sees how peaceful the two Demon Slayer brothers are, it makes him miss his younger brother.
Sanemi in Rage
Sanemi yells at the Upper Rank for cutting his younger brother and runs at Kokushibo while the Upper Rank tries to kill him by cutting off his head. He slides under the Upper Rank’s legs and cuts them off. He uses the Wind Breathing, First Form: Dust Whirlwind Cutter as Kokushibo jumps into the air. Kokushibo draws his sword to block the attack. Sanemi is disgusted by the eyes and moving flesh on Kokushibo’s blade.
He attacks Kokushibo with Wind Breathing, Second Form: Claws, Purifying Wind, but the Upper Rank blocks it with a basic attack with the chaotic blades. As he was trying to block the Breathing attack, Sanemi fell from the sky and tried to cut Kokushibo with his flesh sword, but he failed.
Kokushibo is surprised when Sanemi tries to stab him through the bottom of his head with Genya’s Nichirin Sword. The Upper Rank gracefully moves out of the way of the blade and cuts it off of Sanemi’s foot.
During this time, Gyomie, the Stone Hashira, is also participating in the battle. When Gyomei used Stone Breathing: Second Form, Genya yelled Muichiro’s name and asked him to get a strand of Kokushibo’s hair. He tells Muichiro that he wants to fight until the end and do whatever it takes to protect his older brother. He was planning to eat Kokushibo’s hair to gain some powers.
Genya Coming Back Into Battle, But at What Cost?
Genya feels his body coming together almost right away as he eats Kokushibo’s hair. He also remembers that Gyomei broke off a piece of Kokushibo’s sword, and he wonders how much more power he can get by eating that too. But then he hears Muzan’s voice again, and he wonders if he is becoming more like a real demon.
As the three Hashira go back into battle, Genya thinks about what Tanjiro said about how the weakest fighters have the best chance of turning the fight around. He then takes Kokushibo’s discarded demonic blade and eats it.
Genya comes out of the shadows as a full demon and fires his double-barreled shotgun at Kokushibo.
Genya Becoming More Like Kokushibo
He shoots at the Upper Rank with his mutated shotgun, but all of the bullets bounce off of him. But even though he deflected the bullets, they still bent back toward him as if they were alive. Kokushibo’s skin is pierced by Genya’s bullets as he sees that Genya now looks like him, with red eyes and a Demon Slayer Mark that looks like a flame on the right side of his forehead. As he looks at Genya’s new look, the bullets that hit Kokushibo’s skin change into a big wooden tree that pins him to the ground and keeps him from attacking Muichiro.
Kokushibo yells at the top of his lungs because he is angry and upset. As he roars, dozens of the chaotic slashes come out of his body. They cut off the bottom half of Muichiro’s body, making sure he dies, and they also cut Genya in half vertically.
Battle Coming To An End
The battle goes on for a little while Genya rests. In the end, Kokushibo, the Upper Moon Rank One is defeated by the combined efforts of Genya Shinazugawa and three Hashira, Muichiro Tokito, Sanemi Shinazugawa and Gyomei Himejimaro.
Gyomei is completely shocked by the fact that Sanemi lost consciousness and still fought the Upper Rank. He puts Sanemi on the ground and says, “I don’t know how you did it.”
Genya says out loud his brother’s name, Gyomei’s name, and Muichiro’s name to see if they are okay. Gyomei comes close to Genya and tells him that everyone is fine except Muichiro. Genya tells him to help the Mist Hashira right away.
Genya’s Final Moments
Gyomei lays Sanemi’s unconscious body in front of Genya to show him that he is okay and out of respect for him and his wishes.
Genya’s last words to him were that he was the nicest person in the world. Sanemi screams at his brother to stay alive and begs God not to kill the only sibling he has left. He cries and screams as his brother slowly dies. Sanemi screams and calls out Genya’s name in mental pain because he can’t believe that his brother is really gone.
Final Thoughts – Who Killed Genya / How Did Genya Die?
During one of the most iconic fights in Demon Slayer between the three Hashira and Genya vs Kokushibo, Genya loses his life because of gaining demon-like characteristics. He tries his best to contribute to the battle but dies in the end.
To answer who killed Genya, it mainly was Kokushibo, and to answer How did Genya die, it was due to becoming a demon in the end after consuming a lot of Kokushibo flesh.
