Demon Slayer: Kimetsu no Yaiba

After completing their mission on Mugen Train, Tanjiro and his friends are recuperating in the Butterfly Mansion. Though, Tanjiro sneaks out and visits Rengoku's house to pass his messages. Tanjiro got irritated at first because Shinjuro insult his own son, Kyojuro, who just passed away, but as soon as Shinjuro sees Tanjiro's earrings, he becomes a frenzy.

Tanjiro, Nezuko, Zenitsu, and Inosuke are assigned on a mission with Uzui. They are heading to a town that always shines in the night, the Entertainment District. Uzui's wives have been infiltrating the brothels to gather intel about the demons, but they lost contact. So, Tanjiro and his friends are going on a mission with their disguise.

Tanjiro and his friends infiltrate the brothels to get information about Uzui's wives. Inosuke breaks into Makio's room when he heard about her name from the workers. Meanwhile, Zenitsu hears a girl crying and rushes to her. He is surprised when he sees a wounded girl and a messy room, but suddenly there's someone behind him.

Zenitsu realises that Warabihime is a demon, but at the same time, she also realises that Zenitsu is a member of the Demon Slayer Corps. Shortly afterwards, Zenitsu disappears, and his whereabouts are unknown. When Tanjiro and Inosuke are gathered for a regular meeting, they are told by Uzui that they must leave this district.

The master of Kyogoku Brothel tells Uzui about Warabihime. And Uzui suspects her of being a demon. Uzui searches for the presence of the demons while he goes to Hinatsuru's place, who is said moved to a low-class brothel because of her illness. But there, he finds Hinatsuru trapped by Daki's obi. Meanwhile, Tanjiro is struggling to fight against Daki.

Tanjiro beats at the onslaught of Daki with Hinokami Kagura. However, the obi demon that has escaped from its lair after being attacked by Uzui, Inosuke, and Zenitsu, then enters the main body. Now, Daki becomes more powerful. Furthermore, when the people heard the commotion and came out of the buildings, Daki attacks them.

Tanjiro is furious with Daki who despised human life. He pushes Daki harder than before, but his body is already over the limit. When he falls and is now in a pinch, Nezuko comes to help him. However, Nezuko changes her appearance to become more demon-like during the fierce battle.

Uzui confronts Daki and Gyutaro, another demon who emerged from Daki's body. Uzui fights fiercely against those two, but the poison he got from Gyutaro's attack drains his strength. And then, Zenitsu who is still asleep, Inosuke come to help. Followed by Tanjiro who had put Nezuko back into the box.

Hinatsuru was using poison extracted from wisteria flowers and gives Gyutaro a moment of respite, but Tanjiro and Uzui's attacks are thwarted at the last moment. Furthermore, Gyutaro disappeared from Uzui's sight by using his Demon Blood Art and attacking Hinatsuru. Tanjiro and Uzui try to save Hinatsuru, but Daki's obis blocked their way.

Tanjiro and Uzui are separated because of Gyutaro's Demon Blood Art. Tanjiro joins Zenitsu and Inosuke, who are struggling, and the three of them finally succeed in beheading Daki. However, when Inosuke tries to take away Daki's head, Gyutaro's sickle pierces his heart. Uzui is knocked out, Tanjiro and his friends are in grave peril.

At the end of a fierce battle, Tanjiro and Uzui decapitated Gyutaro's head. Meanwhile, Zenitsu and Inosuke decapitated Daki's head at the same time. However, Gyutaro unleashes his Demon Blood Art and covers the district in the wreckage. Tanjiro wakes up and joins up with Nezuko and Zenitsu, but Inosuke and Uzui are on the verge of death, having been poisoned by Gyutaro.
