Kimetsu no Yaiba - Season 2

Rengoku Kyojuro the Flame Hashira begins to solve the case of the deaths in the Mugen Train.

Tanjiro (with his sister in tow), Zenitsu, and Inosuke meet Kyojuro inside the train where they fall into a deep sleep thanks to Enmu's magic.

The effects of Enmu's blood demon art become clear, making the protagonists face their individual, inner struggles. Tanjiro desperately looks for a way to negate the spell.

Tanjiro manages to break free from the demon-art dream. He finds Enmu, and the battle begins. Enmu reveals a more holistic, sinister agenda behind his actions, placing the demon slayers into a sticky challenge.

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 fighting causes the train to derail. 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 tries his best to keep up with him. The Flame Hashira has one goal: to protect his comrades even if it costs him his own life.

Following the death of Kyojurou, Tanjiro visits the Rengoku residence to deliver Kyojurou's last messages to Kyojurou's brother and father. Four months later Tanjiro, Zenitsu, and Inosuke are tasked with visiting an Entertainment District along with the Sound Hashira Tengen Uzui.

Led by Sound Hashira Tengen Uzui, Tanjiro, Inosuke and Zenitsu disguise themselves so they can get hired in the Entertainment District.

A mysterious Oiran is creating havoc in the brothels, but who is she?

Tanjiro and Inosuke further continue the investigation even after Uzui's disapproval of their participation in the mission.

Tanjiro continues to fight Daki and starts using Hinokami Kagura instead of Water Breathing. Tengen saves one of his wives who had been stuck in Daki's belt. Inosuke, Zenitsu, and Tengen's other wives fight the belt demon.

As the fight between Tanjiro and Daki continues, Daki causes immense damage to the district resulting in Tanjiro turning berserk due to rage.

As Nezuko rushes to aid Tanjiro during a critical moment, her appearance begins to gradually take on a demon form as she sustains Daki's attacks.

Putting Nezuko to rest, Tanjiro, along with Inosuke and Zenitsu, rushes to Uzui's aid, against his battle with the Upper Six Demons- Gyutaro and Daki.

Gyutaro evades Uzui and goes after Hinatsuru. Tanjiro and Uzui rush to save her, but Daki's obi blocks their way.

Tanjiro wakes up to find himself surrounded by burning debris with Gyutaro laughing delightedly at his plight.

In the battle aftermath, Tanjiro and Nezuko search for the others. Suma pleads for Tengen to live, and Nezuko helps him. Tanjiro smells their scent and sees the demons arguing viciously. Gyutaro recalls his past.
