Last month, Viz media posted the Chainsaw Man manga trailer which was unnerving and awesome at the same time. On October 10, Viz media then released a "behind the music" to the trailer on their Twitter account. The music video had to be censored multiple times due to "shocking expressions," and featured high-octane opera vocals as its soundtrack.
The manga began serialization in Shueisha's Weekly Shonen Jump on December 3, 2018. It also debuted on the same day in Viz Media's digital English edition of the magazine. Viz describes the plot as:
"Denji's a poor young man who'll do anything for money, even hunting down devils with his pet devil-dog Pochita. He's a simple man with simple dreams, drowning under a mountain of debt. But his sad life gets turned upside down one day when he's betrayed by someone he trusts. Now with the power of a devil inside him, Denji's become a whole new man—Chainsaw Man!"
Viz released the first compiled volume on October 6, 2020.
As of August 2020, Chainsaw Man has over 3 million copies in print, and the digital sales of the manga series started in Weekly Shonen Jump in Japanese and the Shonen Jump app in English in December 2018.
