Ufotable Studios to come up with their best move ever
Intense Battle Scenes
The action would be close: that is, the Demon Slayer Corps would face Muzan and the Upper Moon demons. They’re not guaranteed to be cinematic, but there should be tense, action-oriented battles with fast sword sequences, demon abilities, etc.
Transformation of Muzan Kibutsuji
It is because of this that Muzan was able to master the power of shapeshifting and the perception of his environment. His is would dominate the plot and his gruesome shapes would be taken as the issues.
The Hashira's Fight
The nine strongest members are called Hashira who would step in and each demonstrate the abilities and determination of a demon slayer. Such battles would be angry and formative of the plot.
Visuals and Animation
The studio, as is Ufotable, is evident that they produce beautiful animations and with this arc referred to as the Infinite Castle arc, the fight scenes would be a beautiful mixture of intense fighting, colors, and details especially with demon’s illustrations. It also could be a great cinematic moment for anime and, possibly, reveal the climax of the story.
