haven't seen it but I'm going to guess that Dog Man and similar YA + manga make up most of the top spots.
One manga is at #18 (My Hero Academia book one), the rest of the top twenty is Dog Man, Raina and other kids or YA.
Dog Man’s ten volumes alone are 13% of all comics sold through bookshop-type retail (& that’s probably a lesser fraction of what copawganda moves to libraries and direct through Scholastic), and only displaced from the top ten at #5 and #8. Pilkey did 4.2 million units, Raina 1.3.
