What was the top-selling manga in 2020?
In 2020, the top-selling manga was Demon Slayer, with over 82.3 million copies sold. This was largely due to the anime's comeback and the manga's finale that year, and these numbers blew out the second and third most-selling mangas in 2020, with Kingdom and One Piece selling 8 million and 7 million copies each, respectively.
