This is a compilation of recommendations for short manga (normally 7 volumes or less, but I made a few exceptions) made by reddit's manga subreddit. - The numerical order is ordered in 3 alphabetical "levels": first are the manga I read, then...
these are manga that need an anime or second anime be cause the first one sucked, or was incomplete. Alphabetical order, i add a description if i feel it's necessary.
Must read (This is a personal list, so I'll remove those entries I already started/ended)
Very messed-up, major mindfucks, things like that. Really grim and dark and make the reader go "Nooooo!!!/Whaaaat?"
