A few thoughts on Demon Slayer: Kimetsu no Yaiba Infinity Castle
Swordplay this precise pairs well with Sekiro: Shadows Die Twice, whose one-armed shinobi cuts through demons and warlords in a haunted feudal Japan. Ghost of Tsushima gives the same weight to a lone blade and a beautiful, bloody landscape. In print, Rurouni Kenshin follows a wandering Meiji-era swordsman carrying old kills, close kin to Tanjiro's steady, mournful resolve.
The rest of the Demon Slayer saga, arc by arc
Infinity Castle picks up straight from the fourth season to open the final war against Muzan's Upper Ranks, but Tanjiro's fight really starts back at Mt. Natagumo and the Asakusa Arc. Mugen Train, the Hashira Meeting Arc and Sibling's Bond fill in the training, loss and alliances that built toward this siege, so watching them first pays off everything Infinity Castle assumes you already know.
Sword-fighting action with real weight behind every clash
The Hashira fight with breath techniques honed for years, and that same discipline drives Jujutsu Kaisen's cursed-energy duels and Rurouni Kenshin's reverse-blade swordsmanship. Sekiro: Shadows Die Twice and Ghost of Tsushima put that same precision in your own hands, trading anime spectacle for a sword fight that punishes a single mistimed parry.
Anime that throws its whole cast into one last epic battle
Infinity Castle gathers every surviving Hashira for the opening stretch of a war years in the making, and that same all-in structure drives Fate/stay night: Heaven's Feel II and Puella Magi Madoka Magica's Rebellion, both franchise entries built around a cast's final stand. Kabaneri of the Iron Fortress and Mobile Suit Gundam 00 scale that same idea up to full battlefield chaos.
