Well it's full name is Jojo's Bizarre Adventure; it's about a main character with the nickname Jojo and they go on an adventure and it is bizarre (right what it says there on the tin). Tis the second longest running manga in the world (it is i think 24 or 23 years old and still running)
God...they have ALOT of homage (Rohan has a wing of an art museum dedicated to him, Castlevania and Touhou have characters based off of it, there's a Japanese music video where one guy is supposed to be Jotaro) just ALOT of stuff because it's so incredibly popular (and for some reason japan REALLLLY loves their fictional characters)
It's INCREDIBLY infamous for slaughtering (and boy do I mean slaughter) almost all of it's characters; out of all of those videos you have just seen only 6 of those characters are still alive in the story thus far. Also, it is Seinen (made for guys 18+ but it's SOOO BEAUTIFUL AND SWEET AT TIMES~) but extreme gore (mostly towards men & dogs) and language are verrrry common indeedy. Also, in the series there is 1 or 2 fights that take up more than 2 chapters (those are normally the huge, important fights)
The art design is also AMAZINGLY GOOD and you can really tell how Araki's artwork has developed over the years. ALSOOOO, it is....fabulously manly (no I'm serious, the series is full of homoerotic moments between guys that it's just hilarious)
But yeah...you WILL find moe-moe moments but they're normally given to girls and such.
It's INCREDIBLY original in plot (although the characters/setting/idea/plot changes each part, it still keeps the overall story of the Joestar Bloodline). *nodnod* Yup....oh and they take place in different timeperiods, locations, and (now) universes.
So yeah...OH and only part 3 was translated and brought to America (the rest you have to read online....and I must warn you...part 4 has a FAILTRANSLATION although people are now in the middle of redoing it)
and for some reason, Steel Ball Run and Stone Ocean (parts 7 & 6 respectively) are always separated from parts 1-5 on manga sites >.>
ANYWHO YEAH! I can't really sum up the series anymore than this because it's soo.....bizarre and the everchanging stories kindof...yeah
YOU JUST READ IT
Btw, totally don't watch the 13 episode OVA of part 3....just don't (and the MOVIE CUT OUT SPEEDWAGOOOOOOOON!!! WHYYYYY?!!) ;-;
Also, there are amillion music references (the name "jojo" came from the beatle's song Get Back)
so yeah. READ NAO~
*End Happy Rand
