Demon Slayer: Kimetsu no Yaiba

A new order has been given to Kyojuro Rengoku the Flame Hashira. The mission is to investigate the "Mugen Train" that has eaten more than forty people. After leaving Demon Slayer Corps headquarters, he sets off on his mission to the Mugen Train, but...

After Tanjiro and his friends completed their training in Butterfly Mansion, they head for their next mission to aboard Mugen Train. They meet up with Rengoku there, who has already boarded the train. Tanjiro is overwhelmed by high spirited Rengoku. Zenitsu is frightened by the demon, and Inosuke is excited by the train. A new battle awaits on the train with so many passengers.

Tanjiro spends a happy time with his family. But actually, it's a dream world made by Enmu, the Lower Rank One demon. Enmu's aim is to invade Tanjiro and friends' unconscious realms and destroy their "spiritual core." Will they be able to wake up before their spiritual cores are destroyed?

Tanjiro realised that he's inside a dream. In order to wake up from his dream, he has to cut his own neck. Meanwhile, Enmu's collaborators who have entered their unconscious realm to destroy Tanjiro and his friends' spiritual cores are growing impatient as they fail to achieve their goal.

After fusing with the Mugen Train, Enmu takes more than 200 passengers as his hostages. In every car, there are Enmu tentacles that want to devour the passengers, but Tanjiro doesn't have the ability to protect them alone. However, Inosuke is awakened and comes to help. Followed by Nezuko, Zenitsu, and Rengoku, they join the battle. The all-out battle for protecting the passengers begins.

Tanjiro and Inosuke managed to cut Enmu's head off. The Mugen Train overturns, Tanjiro and his friends are thrown off from the train. With a severe wound, Tanjiro feels relieved after hearing from Rengoku that the passengers are safe. But then, another demon appears in front of them...

Tanjiro and Inosuke can only watch the fierce battle of Rengoku and Akaza. No matter how many times Akaza got slashed by Rengoku, he just recovers instantly. In order to put end to the battle, Rengoku unleashes his esoteric art with all his might. Without letting anyone die, Rengoku's deadly battle comes to an end.
