I've been out of the manga scene for a year. what is good now?
Do you want to what is good or what is the latest craze? Whats good hasn't really changed much, though a few things have gotten shittier. The best new series I can think of in the last year have been things like Assassination Classroom and Onepunchman (which is okay).
As for whats the latest craze... I mostly suggest you ignore the flavor-of-the-month mangas actually.
What's good is only what matters.
I'm telling you, Himu, read Watashi ga Motenai, it's the feel good manga of our generation. You'll laugh, you'll cry, and maybe, just maybe, you'll learn a little something about yourself.
