Anime 47778 Kimetsu No Yaiba Yuukaku-hen Episode 9

Synopsis

Tengen remembers visiting his family grave alongside his wives, having promised them to live "the flashiest lives possible" in their honor. In the present, he and Tanjiro close into Gyutaro’s neck, but the demon has managed to neutralize the wisteria poison and regenerate both his legs. Using a new Blood Demon Art, he fends off Tengen and vanishes, suddenly appearing alongside Hinatsuru. Seeing her life in danger, Tengen reminisces on how he had promised his wives that they would retire from fighting, if they managed to defeat an Upper Rank demon. Unwilling to let another person die, Tanjiro combines his Hinokami Kagura and Water Breathing, unleashing a very fast charge that stuns the Upper Rank and saves Hinatsuru. Tengen shows him his gratitude and joins him in attempting again to slice off Gyutaro’s head, while Zenitsu and Inosuke continue to fend off Daki’s obi. Gyutaro stops the blades from hitting him and unleashes his Blood Demon Art again, forcing Tengen to throw himself and Gyutaro away to save Hinatsuru and Tanjiro. With Tengen continuing to fight Gyutaro alone, Tanjiro joins Zenitsu and Inosuke in battling Daki. Coordinating their attacks, Tanjiro and Zenitsu open the way for Inosuke, who saws off Daki’s head with his swords and runs away with it, preventing reattachment to her body. Without warning, Gyutaro appears and stabs Inosuke from behind through his chest, retrieving Daki’s head. Tanjiro turns around, only to see Tengen’s severed hand and unconscious body on the ground. Devastated for not being able to help Inosuke and Tengen in time, Tanjiro freezes. Zenitsu pushes him off the roof to save him from an incoming obi attack.
