with how mangas used to perhaps take up the trouble of coming up with a plot,
the mainstream new age manga is nothing more than a formula,
which is a royal pain in one's behind since there's nothing much to it.
But i suggest that a couple of mangas which nearly broke away from this formula,
were mugen no junin (blade of the immortal) which we might be posting up links for
as well as Blame.
Action packed, so to speak,
but incredible plots,
with no prerequisites required - at least none which have one resign oneself to bad artwork.
