Yes... when curiosity gets us, we often read the manga... Though, I tend to read the manga first before there's an anime announcement. haha
I used to read JJK when there wasn't an anime yet, but I forgot where I stopped and never really checked the anime... Same with KnY... After reading the manga, I only watched the first season and first movie. haha
Really? Well, it's always better to read the manga because it's more complete and you don't get so many spoilers from those who watch the anime when it comes out. In my case I've never been able to finish reading a manga, not that I've tried with many stories, but I guess I'll finish JJK.
There's a first for everything and JJK must be the one for you... 😎✨
