Demon Slayer Chapter 190

Demon Slayer Chapter 190, titled "One After Another," intensifies the Sunrise Countdown Arc as the Demon Slayers launch a desperate, coordinated offensive against Muzan Kibutsuji, activating their red blades and bringing more fighters into the fray. Obanai Iguro, realizing his near-fainting spell from focusing too hard on activating his red blade was a mistake, is snapped back to reality by Sanemi Shinazugawa's warning about Muzan's relentless attacks. Obanai vows to fight for Mitsuri Kanroji, who is currently incapacitated. Though he loses all sensation in his body except his sword hand, he successfully dodges Muzan's attack mid-air, surprising Muzan and Giyu Tomioka, who initially struggled to intercept the demon's blow.

Muzan, attempting to attack Obanai in mid-air, is further shocked when his right arm and whips are inexplicably severed by a jagged, invisible cut. Forcibly regenerating his limb with a delay, Muzan continues his assault on Gyomei Himejima and Sanemi, only to lose his left arm to a similar mysterious cut. He deduces the presence of three hidden attackers wielding serrated blades, who are also targeting him. Muzan swiftly analyzes his surroundings, slicing at the approximate locations where he hears the air parting. With his attacks, he strikes Inosuke Hashibira, Kanao Tsuyuri, and Zenitsu Agatsuma, who suddenly become visible as seals on their heads are cut. They express surprise at Muzan's speed, while Gyomei is relieved to see them alive, with Inosuke humorously boasting about his abundant seals.

Muzan interrupts Inosuke's monologue with a whip attack, but Obanai seizes the opportunity to slice off both of Muzan's arms with his bright red blade, causing a noticeable delay in Muzan's regeneration. Sanemi, heartened by this, notes the effectiveness of the red blade to his companions. Kanao and Zenitsu quickly apply new seals and launch their respective attacks: Flower Breathing, Fourth Form: Crimson Hanagoromo and Thunder Breathing, First Form: Thunderclap and Flash. Muzan, enraged, dismisses them as "pesky flies" and their "pitiful tricks," but is again interrupted by Obanai, who executes Serpent Breathing, Third Form: Coil Choke.

Gyomei reflects that the arrival of reinforcements and Obanai's red blade manifestation have greatly aided their efforts, allowing him to concentrate more. He clashes his weapons together, turning them bright red, and with a powerful swing, severs Muzan's entire left shoulder, exposing his spine. As Muzan pauses, Sanemi yells at Giyu to prepare, then strikes Giyu's blade, turning both their weapons bright red. A Kasugai Crow announces that dawn is now only an hour and three minutes away, and Sanemi confidently declares they will chop Muzan into pieces before sunrise, setting the stage for the final, desperate struggle in the climactic Sunrise Countdown Arc of the Demon Slayer manga.
