The Demon Slayer Corps are drawn into the Infinity Castle, where Tanjiro, Nezuko, and the Hashira face terrifying Upper Rank demons in a desperate fight as the final battle against Muzan Kibutsuji begins.

Tanjiro Kamado, joined with Inosuke Hashibira, a boy raised by boars who wears a boar's head, and Zenitsu Agatsuma, a scared boy who reveals his true power when he sleeps, boards the Infinity Train on a new mission with the Fire Hashira, Kyojuro Rengoku, to defeat a demon who has been tormenting the people and killing the demon slayers who oppose it!

The Seraphim, a mystical spirit race who act as a stabilizing force in the land, blessed a human boy known as Sorey with powers. Sorey's encounter with Alisha and Lunarre leads him to leave on a journey to becoming the Shepherd and saving the world.

Mikiya Kokutou gives Shiki Ryougi a cat to watch, as he will be away for a little while. Though Shiki protests, he leaves the cat anyway, and Shiki is stuck trying to understand her new feline companion. But as luck would have it, the cat seems to have taken a liking to Mikiya and misses him. Later in another part of the city, Ririsu Miyazuki visits the place where her dear friend committed suicide. She intends to end her life as well, but she meets Fujino Asagami, a blind classmate with a traumatic past. Though the two girls don't have much in common, Asagami reminds Miyazuki of her lost friend and helps her understand her pain. Two months later, Mikiya elects to celebrate New Year's with Shiki instead of his family, which makes his sister Azaka very upset, leading to her spending the holiday with her school friends. As the snow begins to fall, Mikiya reflects on what he wishes for most of all: that Shiki's life be filled with happiness.
