Who Killed Shinobu, the Insect Hashira?

In this post, we will go over who killed Shinobu and How in Demon Slayer: Kimetsu no Yaiba.

Shinobu is the Insect Hashira in Demon Slayer. She is one of the most essential characters in the Final battle that takes place in Infinity Castle Arc.

She is the younger sister of Kanae Kocho, who used to be Flower Hashira. Shinobu and her sister joined the Demon Slayer Corps after a demon killed both of their parents. She did this so that other people wouldn’t have to go through what she did.

Who Killed Shinobu Kocho, the Insect Hashira?

Doma, the Upper Moon Rank Two, kills Shinobu Kocho during the Infinity Castle Arc. Shinobu plans to kill Doma and avenge her sister, Kanae, by injecting Doma with tons of poison. But, during the battle, Doma overpowers Shinobu and kills her.

Doma sees Shinobu at the door to his room while he is eating in a room in the Infinity Castle with some of his disciples. When another meal walks into his room, he is happy and thanks Nakime (the owner of Infinity Castle). Shinobu’s student, who is still alive, begs him to save her.

This makes Doma mad, so he tries to kill her, but Shinobu jumps in and saves her. She asks the young woman if she is okay, but before she can answer, the young woman breaks apart and dies right in front of Shinobu’s eyes.

Shinobu Is Angry About Her Sister, Kanae

Shinobu meets up with Doma. She is angry that Doma keeps saying that he saved the girl by killing her. She sees that Doma’s primary weapon is a pair of sharp fans, and she asks him angrily if he remembers her older sister’s haori.

She used to wear a haori with butterfly wings on it, which is how Doma finally remembers her. Shinobu gets even madder when he jokes about being sad that he can’t eat Kanae because the sun is rising.

Shinobu vs Doma

Hashira attacks him quickly with her Insect Breathing, Dance of the Bee Sting: True Flutter, which sends a powerful stab right into Doma’s right eyeball. Doma doesn’t understand why he can’t stop it.

Doma compliments Shinobu on how fast she is, and then she uses Blood Demon Art: Frozen Lotus to push her back, which causes her to breathe in the cold air by accident. When he tells her that the only way to kill a demon is to cut off its head, he suddenly bends over and throws up blood. He’s getting sick from the poison she gave him.

Upper Moon Rank 2 quickly gets rid of the poison and gets better after getting stabbed. Shinobu tries to poison him four more times, but Doma is now completely immune to her attacks. He makes fun of her the whole time because she is getting sick from breathing in his frost.

Poison Doesn’t Hurt Doma (Yet)

Shinobu hits him with Insect Breathing, Dance of the Dragonfly: Compound Eye Hexagon. She is now hedging her bets by using a six-stab attack to kill him with a large dose. But at the same time she attacked him, he attacked her and cut her collarbone, ribs, and lung.

Shinobu gets ready to attack Doma again, even though she is badly hurt and in a lot of pain. She attacks and confuses him with Insect Breathing and Dance of the Centipede: Hundred-Legged Zigzag. She hits Doma right in the neck, which pierces him and sends him flying up toward the ceiling. Shinobu thinks she has won when her attack kills Doma and makes her sick. Even though she is tired and hurt, she thinks she has won.

Doma Kills Shinobu and Absorbs Her

Shinobu dies when Doma absorbs her, but Doma gets better almost as soon as Shinobu hits her, which makes Shinobu even angrier. Shinobu is tired, hurt, and very close to dying when Doma grabs her as they fall from the ceiling. He hugs her like a bear and makes fun of her. He tells her that her whole plan to beat him was a waste of time, tells her that she will be happy as a part of him, and then asks her for her last words.

Doma breaks Shinobu’s body in his arms and starts to absorb her at the same time that her student Kanao Tsuyuri shows up.

Final Thoughts – Who Killed Shinobu, the Insect Hashira.

The sacrifice of Insect Hashira is significant when it comes to killing Doma. It was only appropriate for Shinobu and Kanao to participate in this battle as Doma was the one who killed their sister Kanae earlier.

In the end, to answer the question of who killed Shinobu in demon slayer? It was Doma, the Upper Moon Rank Two.
