Demon Slayer: Kimetsu no Yaiba - The Movie 2: Infinity Castle

As the fortress keeps shifting, the Corps split across endless halls and are forced into decisive one-on-one battles. Zenitsu tracks down Kaigaku and cuts ties with his former senior in a duel that turns on pride and timing. In another wing, Shinobu confronts Doma and springs a plan prepared long before she entered the castle; Kanao and Inosuke carry the result to its end. Deeper inside, the castle’s master warps corridors to isolate intruders while Hashira converge on a foe whose blade work has outlived generations. The fight drags in Muichiro and Genya and becomes a struggle against technique, regeneration, and the cost of staying on one line of attack. Outside maneuvers lay a snare for the one enemy who never appears without turning the field against his hunters. The castle answers by folding rooms and dropping floors until the structure itself begins to fail, pushing survivors toward a final convergence that will not stay contained below ground.
