It's honestly kinda crazy that Kimetsu almost beat JJK. Like 1.4 million is a big gap, but considering that the series ended last year and this was all backlog makes that a really crazy accomplishment. Tokyo Revengers, my feelings towards the series notwithstanding, did really well, even without a top-tier adaptation like Kimetsu and JJK.
One Piece dropping to sixth is insane. Yes, another volume would have allowed it to jump to fourth, but the fact that that's the highest it could have gone is crazy.
CSM and Spy x Family are gonna explode when their animes finally drop if they're already doing numbers like this (especially in CSM's case which ended last year).
