Kimetsu no Yaiba

Flame Hashira Kyojuro Rengoku receives new orders: Travel to the Mugen Train, where over forty people have gone missing, and conduct an investigation. Leaving the Demon Slayer Corps Headquarters, he sets off on this new mission.

Kyojuro Rengoku heads to the Mugen Train to investigate the disappearance of over forty passengers and encounters a demon along the way. After saving the people attacked by the demon, he finally arrives at the Mugen Train. What lies ahead of him?

Trapped in Enmu's spell, Tanjiro, Zenitsu, Inosuke and Kyojuro fall closer and deeper into an eternal slumber. Faced with death, Tanjiro is forced to confront his demons to save them.

With Tanjiro successfully awakening from his dream, he confronts the demon responsible, Lower One Enmu. But the situation challenges Tanjiro's resolve when Enmu proves more powerful that any demon he's ever faced.

The battle with Enmu continues as Inosuke, Zenitsu and Rengoku awaken from the spell. Tanjiro and Inosuke try to pinpoint the demon's weak spot, while the others focus on protecting the passengers in the train.

Tanjiro has finally slashed Enmu's neck with the help of Inosuke. The tremors from the train flipped it over the rails. As silence deepens a mysterious figure approaches from behind.

Akaza continues to offer Rengoku the chance to become a demon to improve his skills. Rengoku refuses his offer and is trying his best to keep up with him. The fire Hashira has one goal:to protect his comrades even if it costs his own life.

After the Mugen Train incident, Akaza visits Muzan Kibutsuji. Guided by a crow, Tanjiro Kamado heads off to the Rengoku residence to convey Kyojuro Rengoku's last messages to his father and little brother. Tanjiro's group return to the Butterfly Mansion.

One day, Tanjiro returns to the Butterfly Mansion and finds Sound Hashira, Tengen Uzui, attempting to take Aoi and Naho away on a mission against their will. Tanjiro, Zenitsu and Inosuke offer to go on that mission instead, and they head to their next destination - the Entertainment District.

After arriving at the Entertainment District, Tanjiro and his comrades infiltrate each House where Uzui's wives, Suma, Makio and Hinatsuru, work. While working as apprentices and searching for their whereabouts, Inosuke hears that Makio has been shutting herself away from everyone in her room.

Realizing Zenitsu is now missing, Tanjiro and Inosuke re-arm and look for signs of the demon. Tanjiro goes in alone and is confronted by Upper Rank Six. 

Facing Daki alone, Tanjiro tries to use Hinokami Kagura but is hampered by the extreme stress it causes his body. Inosuke and Tengen locate the demon's victims and meet the demon responsible for abducting Zenitsu and his wives. 

Furious at Daki's disregard for lives, Tanjiro angrily confronts her, causing her to experience Muzan's memories of an old enemy. His excessive use of Hinokami Kagura soon brings him to his knees in pain.

As Nezuko fights and overwhelms Daki, she nearly loses herself and forces Tanjiro to stop her. Daki prepares to exact revenge but Tengen arrives.

Facing the dual holders of Upper Six, Tengen, Tanjiro, Inosuke and Zenitsu battle Daki and Gyutaro head on.

While Zenitsu and Inosuke struggle with Daki's obi, Tengen and Tanjiro are repeatedly forced on the defensive by Gyutaro.

With his friends severely wounded, Tanjiro is confronted by Gyutaro. He offers to turn him into a demon but Tanjiro takes his last stand and attacks despite his severe injuries.

After defeating the Upper Rank Six demons, Nezuko quickly heals Tanjiro, Inosuke and Tengen of the poison. Tanjiro heads out to finish off the demons while Gyutaro reminisces about his past.
