Fighting of Demon Slayer Infinity Castle Arc:

Gyomei, Sanemi, Muichiro & Genya vs. Kokushibo (Upper Rank One)

The most brutal and strategically complex battle. Kokushibo, the former Demon Slayer and original Moon Breathing user, is Muzan’s strongest subordinate. The Hashira and Genya unleash everything they have. Muichiro and Genya both make ultimate sacrifices, with Muichiro activating his Red Blade and Genya using his demon-eating ability to critical effect. Gyomei and Sanemi, the two strongest Hashira, coordinate brilliantly, pushing Kokushibo to an extreme.

Shinobu vs. Doma (Upper Rank Two)

This highly anticipated fight sees Shinobu, the Insect Hashira confront Doma. Shinobu’s vengeance fuels her, but Doma’s cryokinesis and immense power are overwhelming. Shinobu, aware of her physical limitations, employs a brilliant, self-sacrificing strategy: she intentionally allows Doma to consume her, having filled her body with a massive dose of potent Wisteria poison.

Tanjiro & Giyu vs Akaza (Upper Rank Three)

This intense rematch in the Infinity Castle, Tanjiro (with Giyu) against Akaza, the powerful Upper Rank Three who killed Rengoku. Witnessing Tanjiro’s Demon Slayer Mark activate and his use of the Transparent World to match Akaza’s speed shows a breathtaking display of evolved power and vengeance.

The Demon Nakime (Upper Rank Four)

Nakime, the biwa demon, controls the Infinity Castle’s architecture with her music. She can shift rooms, manipulate gravity, and separate opponents instantly, making it a chaotic and disorienting battlefield.

Mitsuri & Obanai vs.Hantengu’s :

Mitsuri and Obanai are initially engaged with a further manifestation of Hantengu’s powers or lesser demons controlled by Muzan, and later join the main battle against Muzan.

Zenitsu vs. Kaigaku (Upper Rank Six)

Zenitsu faces Kaigaku, his former fellow disciple of Thunder Breathing, who betrayed their master and became a demon. Kaigaku, now infused with demonic power, uses a corrupted Thunder Breathing style. Zenitsu’s performance is driven by rage and sorrow over his master’s death. He unleashes his new, ultimate Seventh Form of Thunder Breathing.

Tanjiro vs. Muzan Kibutsuji (Final Battle):

The Infinity Castle Arc culminates in humanity’s ultimate struggle against Muzan Kibutsuji, the Demon King. After defeating the Upper Moons, all surviving Demon Slayers, led by Tanjiro, engage Muzan in a horrific, earth-shattering final battle.

Muzan reveals his terrifying new form with rapid regeneration and devastating attacks. The fight transforms into a desperate war of attrition, as Slayers endure continuous assaults, utilizing Tamayo’s anti-demon drug to weaken him, and aiming to hold him until sunrise. Hashira Pillars and key character contributes to this grueling, sacrificial climax. The arc ends with Muzan’s desperate attempt to transfer his essence to Tanjiro, leading to Tanjiro’s temporary demonization and the final, heart-wrenching challenge for Nezuko and the remaining Slayers.

Visual Ufotable Studio Masterclass Performance:

Demon Slayer’s success is undeniable, driven by Ufotable Studio’s iconic animation. Its cinematic quality shines in every Hinokami Kagura’s dynamic sword strike and Water Breathing technique, often blending with traditional Japanese art to create deeply emotive character expressions, such as Tanjiro’s resolve and Zenitsu’s fear. The stunningly crafted world, whether a peaceful wisteria garden or a scary demon lair. Navigating a world in which “demons” are evil, encountering tragic backstories of demons, makes this cinematic journey redefine shonen anime standards.
