The 12th volume of Tatsuki Fujimoto’s Chainsaw Man manga just launched in Japan, and with it comes some updated numbers. According to the volume’s wraparound band and editor Shihei Lin, the series now has physically printed and digitally sold over 16 million copies.
That number is four million higher than it was in December, and that number is likely going to increase further alongside the arrival of the anime adaptation, which shreds up screens starting on October 11.

VIZ Media publishes the Chainsaw Man manga, with all of Part 1 currently available digitally and in print and Part 2 running each week via the Shonen Jump app. Here’s how VIZ describes it:
Denji is a teenage boy living with a Chainsaw Devil named Pochita. Due to the debt his father left behind, he has been living a rock-bottom life while repaying his debt by harvesting devil corpses with Pochita.
One day, Denji is betrayed and killed. As his consciousness fades, he makes a contract with Pochita and gets revived as “Chainsaw Man” — a man with a devil’s heart.
