umm completed as a genre? yeah that won't be happening cause it doesn fit the definition of a genre... and theres already a way to search for completed manga anyways. just go search for it.
and yeah thats not every completed series. just the stuff i've seen or could find (non shoujo/non yaoi/non shounen ai/non yuri probably as well) pretty much shounen and seinen. and yeah theres probably a few ones missing and havent updated list since manick made that completely scanlated option.
