A new trailer for “Demon Slayer: Kimetsu no Yaiba – Infinity Castle” has just been released, and it’s already making waves across social media. The highlight? A fierce and emotional battle between Shinobu Kocho and the demon Doma.
Shinobu’s Revenge Begins
Shinobu Kocho, the Insect Hashira, is known for her calm nature and deadly poison techniques. But in this movie, she’s not just fighting — she’s seeking revenge. Doma is the demon who killed her sister, Kanae, and now Shinobu enters the Infinity Castle with one goal: to take him down.
The trailer shows Shinobu’s graceful attacks clashing with Doma’s icy powers. Her speed, precision, and poison-based swordplay are beautifully animated by studio ufotable. Fans can expect a mix of elegance and intensity as Shinobu risks everything in this one-on-one showdown.
Doma’s Cold Power
Doma, one of the Upper Rank demons, is charming on the outside but cruel and heartless within. He uses ice-based techniques and has a twisted sense of peace. In the trailer, his calm smile contrasts with the brutal fight, making the scene even more chilling.
This battle is not just physical — it’s emotional. Shinobu carries the pain of her sister’s death, and Doma treats it like a joke. That tension is what makes this fight one of the most powerful moments in the series.
Movie Release Details
“Infinity Castle” is the first part of the final arc in the Demon Slayer story. It continues from where “Mugen Train” and “Swordsmith Village” left off. The movie will premiere in North America on September 12, 2025, with early fan screenings starting September 9.
