It's been exactly five years since the Demon Slayer: Mugen Train film was released, and the series hasn't been the same since.
The Demon Slayer: Mugen Train film was released in Japanese theaters on October 16th, 2020, not 2025, and it made history with its astounding success.
Before the anime adaptation was released in 2019, the manga had over 3.5 million copies in circulation, which increased to 10 million in September, around the time of the first season’s finale.
The manga continued to rise through the charts, eventually hitting the 100 million milestone about two weeks before Mugen Train‘s premiere.
The series could already be considered at the peak of its popularity, but Mugen Train‘s groundbreaking success etched its name into anime history.
The film surpassed the long-standing box office records of classics such as Makoto Shinkai’s Your Name and Studio Ghibli’s Spirited Away.
Author summary: Demon Slayer film changed series future.
