Several key characters have been introduced in the Infinity Castle arc, adding depth and complexity to the story:

One of the most anticipated confrontations in the entire film is the rematch between Tanjiro Kamado and Akaza, the Upper Moon Three who killed the beloved Flame Hashira, Kyojuro Rengoku. Tanjiro finally has a chance to avenge Rengoku, but even combined with Giyu Tomioka’s strength, their forces aren’t enough to defeat the overwhelming power of Akaza.
