#5 They’re Insane.
Japan is where reason and logic go to die, so of course, why would their graphic novels be any different? On a bat-shit insane scale of 1 to 10, most manga plots are about a 20. Yet somehow, because they come from such a crazy culture to begin with, I TOTALLY BUY IT! A boarding school where a secret class of vampires attends school with an unknowing bunch of humans, protected only by the two fifteen-year old school prefects? I’m sure it happens all the time in Tokyo!
#4 Engrish
Oddly enough, western culture crops up all the time in manga, often with hysterical results.
Behold WcDonalds!

#3 Easy Access
Thanks to the inter-webs, those of us too cheap to actually purchase volumes of manga can go online and find fan-scan sites. I would highly recommend these two:

#2 You want it, they got it
I know I sound like a used car salesman, but seriously, there are manga’s for everyone. Romance, Fantasy, Drama, Martial Arts, History, Sci-fi, Psychological and the list goes on forever. One word of warning for those who haven’t ever read manga and don’t speak Japanese: DO NOT CLICK ON ANYTHING LABELED YAOI (unless your into gay porn). I’m not joking.
#1 The Art
For my money, the art found in manga is unparalleled. Hino Matsuri is probably my favorite. He has a style that is both exaggerated yet still realistic. He writes fantasy/romance-ish stories that have a way of staying with you after you finish a chapter. A friend of mine, and fellow manga freak, calls his work “sexy”. It’s not dirty or anything, but I think that’s probably the most apt description, it is sexy if not a touch melancholy.
