Demon Slayers vs Enmu

Demon Slayers vs Enmu was a battle that took place on the Infinity Train. It focuses on the battle between Demon Slayers Tanjiro Kamado, Zenitsu Agatsuma and Inosuke Hashibira, Demon Nezuko Kamado and the Flame Hashira Kyojuro Rengoku against Lower Rank 1 Enmu.

Battle
Tanjiro infuriated by Enmu's comments and immediately readies the Water Breathing: Tenth Form - Constant Flux in order to behead Enmu as he unleashes his Blood Demon Art: Whispers of Forced Unconscious Hypnosis. Enmu tells Tanjiro to go to sleep as his hand mouth releases the Blood Demon Art, forcing Tanjiro to lose consciousness and sleeps. However, the Demon Slayer quickly regains consciousness and keeps engaging the Lower Rank with the Water Breathing. Enmu continues using his Blood Demon Art to make Tanjiro fall asleep but keeps waking up from him killing himself in his dream. This keeps happening until Enmu decides to make Tanjiro see his family angry and disappointed at him for them believing that he let them die from a demon. With his own siblings, mother and even his father insulting him, this angers Tanjiro knowing that his family would never badmouth him under any circumstance. Because of this Tanjiro is able to behead Enmu using the Water Breathing: Tenth Form - Constant Flux. As Tanjiro beheads Enmu, he comments that there was no reaction from Enmu being beheaded leading him to believe that whether he himself was in a dream or if he was just overall weaker than the previous Twelve Kizuki member he fought, Rui. Enmu however notes that 'that person' commanded him to kill Tanjiro Kamado along with the other Hashira, and he points out that the Demon Slayer's existence makes him seethe in anger. As he is saying this, a huge bundle of flesh connects Enmu's disembodied head to the ceiling of the train. Tanjiro looks in disbelief and fear as Enmu tells him that even a toddler can figure out why he won't die even if he is decapitated by a Nichirin Blade. He describes that this is not his actual body but that he merged with the entire train with it being his flesh and bones. As Tanjiro tries to cut Enmu, his "head" fuses with the train before that happens. As Inosuke falls towards the engine of the train, he grinds both his Nichirin Blades on the dozens of eyeballs from Enmu's Blood Demon Art and with the momentum of the fall along with his swordsmanship, Inosuke uses his Beast Breathing: Fourth Fang - Slice 'n' Dice to cut away the flesh that protects the neckbone for Tanjiro. With Enmu's neckbone exposed, Tanjiro pleads to his father Tanjuro to help him defeat the final Lower Rank as he transitions between the Water Breathing to the Hinokami Kagura. With that, he uses the Hinokami Kagura: Clear Blue Sky, severing Enmu's head, truly killing him.

With Enmu beheaded, he profusely shrieks in pain and horror as he unleashes his tentacles to attempt to consume all the 200 passengers onboard. They were thankfully stopped by Kyojuro Rengoku and Zenitsu Agatsuma with their respective Breathing Styles.
