Masanori Miyake

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!

One hot summer day a little girl gets lost in an enchanted forest of the mountain god where spirits reside. A young boy appears before her, but she cannot touch him for fear of making him disappear. And so a wondrous adventure awaits...

The movie starts off with Ryotsu (with Honda as his patsy) hatching another crackpot scam with a fake UFO sighting (via fake crop circles and a wire-hanging UFO). But the plan fails per usual, with the Kameari Park Police Box which results in Ohara punishes Ryotsu by subtracting him from the station's group vacation to Hawaii the following day.
