Been reading it lately, and it helps reduce my scrolling time. I've hardly read any, so you can recommend really popular stuff, too.
I've read Vagabond, 20th Century Boys, Claymore (years ago), and some berserk. I just finished reading Teppu, which I thought was an interesting subversion of a lot of anime tropes. I also liked that it was a short run (only 8 volumes). I guess I like seinen, but I've also enjoyed josei like She Loves to Cook, and She Loves to Eat.
Anyway, no shonen please. Hard mode: please nothing about high school
Monster is pretty good and Pluto both by the same mangaka as 20th century boys, my favorite ongoing manga is Chainsawman which is a bit of a shonene but it has no high school stuff in part 1.
Yeah, I actually read Pluto and watched monster. I like urasawa, but I do feel like his stories feel a little too similar
Now that i remember the author of csm made good one shots stories in "look back" and "goodbye eri"
Maybe I'll check that out to see what the csm hype is about
