While Tanjiro fights Daki alone and becomes overwhelmed by the strain Hinokami Kagura. Tengen finds his first wife, Hinatsuru. After he gives her the antidote he goes in search of the demon. Using his hearing to find Zenitsu, Inosuke, and his two wives fighting underground. Inosuke, Zenitsu, and Tengen all get a chance to show off how flashy they can be.
Demon Slayer Season 2 Episode 12 goes to get pains to show how much effort it takes for demon slayers to fight. Even the focus on “breathing,” something we assume would require very little effort, feels exhausting. In a flashback, Tanjiro recalls the intense pressure attempting to use Flame Dance: Clear Blue Sky caused. At the time it’s “sheer force,” was too much for him to handle. In the present, Tanjiro remembers Rengoku’s words: “set your heart ablaze.” He performs Hinokami Kagura: Raging Sun, successful cutting Daki’s obi. The Upper Demon quickly notices the “sharpening” of Tanjiro’s skills. However, he’s still not able to handle Hinokami and collapses.
Daki attempts to gain the advantage and kill Tanjiro while he’s incapacitated on the ground. In danger, Tanjiro uses Recovery Breathing to regain his some of his movement. Throughout this fight, Daki is impressed Tanjiro has kept up, but she’s not the least bit concerned. It’s clear that Tanjiro is already heading towards his end. Regardless, he’s determined to protect the innocent. Meanwhile, Inosuke is terrorizing the women in the brothel as he rampages, while searching for the demon. He finds the hole leading to the demon lair and creepily dislocates his joints to slither through the tunnel. Once inside, Inosuke finds Daki’s Obi, draped around like webbing. He finds he victims trapped inside including Zenitsu.
Maybe you should stay asleep the whole time
Things are going to get real flashy
Suddenly, the sash, with a face and mouth, begins attacking Inosuke. He easily avoids it, while freeing the captured humans. Daki orders the sash to catch Inosuke and the “ten most beautiful,” she can kill all the rest. Makio and Suma help battle the “worm belt,” as Inosuke calls it. Inosuke is concerned if the worm belt isn’t the real body then he will be stuck down their “forever.” Without warning, Zenitsu uses Thunder Breathing, First Form: Thunderclap and Flash, Sixfold, and begins cutting up the sashes. While Zenitsu was causing a ruckus, Tengen was crashing through the ground. He enters the lair in epic fashion. The worm belt instantly identifies Tengen as a Hashira. Tengen attacks, slicing the belt into tiny pieces.
Demon Slayer Season 2 Episode 12 shows us the difference between the trio and Tengen. First the worm belt is impressed with Inosuke’s “intuition”, his ability to “detect murderous intent”. He’s able to avoid the worm belt’s attacks. Zenitsu, who still needs to be unconscienced has amazing speed but wasn’t able to kill the worm belt either. When Tengen appears, the worm belt doesn’t have time to dodge. Tengen’s speed overwhelms her and she’s quickly killed. The gap in power between Inosuke, Zenitsu, and Tanjiro when compared to Tengen and Daki is notable.
