Demon Slayer outsells the whole western comic industry
Demon Slayer is the last big success in manga industry. The anime was incredibly successful and the movie released last year was the highest box office in Japan's history, becoming the 5th highest box office in 2020, after Tenet.
The manga itself has outsold the whole western comic industry last year. It's not a joke. This manga alone sold more comics last year than the whole western comic industry.
