The newest Demon Slayer movie, Infinity Castle, has shocked the Japanese movie industry with its record-breaking opening. In just one weekend, the film earned a massive ¥6 billion, which is about $40.6 million in U.S. dollars. This incredible number has officially broken the previous opening weekend record set by Demon Slayer: Mugen Train, which earned ¥4.6 billion during its debut in 2020.
This major success has confirmed once again just how popular Demon Slayer is, not only in Japan but around the world. The excitement for Infinity Castle had been building for months. As soon as tickets went on sale, fans rushed to buy them. Some movie theaters had long lines of people waiting, and many screenings were completely sold out. Some fans even watched the film more than once during the weekend.
The story of Infinity Castle picks up from where the previous seasons of the anime left off. The main characters; Tanjiro Kamado, Nezuko, Zenitsu, and Inosuke enter a mysterious place called the Infinity Castle. It’s a huge and strange building that constantly shifts and moves. Inside, the Demon Slayer Corps faces off against some of the most powerful demons in existence, including Muzan Kibutsuji, the main villain of the series.
