Manga suggestions?

[senpai]

I won't lie. I'm persnickety when it comes to manga. I used to read a lot of it when I was younger but these days I find it hard to dedicate myself to long ongoing series. Can anyone suggest some relatively short manga titles for me to read? I am open to many genres so long as the story's are good. Here's a list of my favorites to kind of give you a starting point.

-Akira (my favorite manga ever)
-Berserk
-Cage of Eden
-Vinland Saga

I now that's not much but like I said, I don't like that much manga but when I find a series or story that I like I can really appreciate them. I've also been reading a lot of novels and American comics lately so I'm just in the mood for something different.

Some people have recommended titles like Gantz, Claymore, Basilisk, and other dark-themed anime series but I tried all those and couldn't get into it.

Thanks everyone!
