Thank you pookie
Bro already mentioned everything I wanted to recommend
It's because there's not a lot of shounens actually worth reading except these, a lot of the others are either really boring or full of weird shit.
True
Kekkaishi is good very shonen.
It has an anime
some good shonen mangas like Kagurabachi, ones which don't have anime adaptation
