JoJo

JoJo is a nickname shared by the main protagonists of JoJo's Bizarre Adventure. The name comes from the recurrence of "Jo" in the character's name.

In the case of Josuke, he takes his nickname, because the second kanji of his personal name, "suke", can also be read "jo". There's an unusual "exception" with the name Giorno Giovanna, who is called GioGio. However his name in katakana is written "Joruno Jobana", to reflect the Italian pronunciation of GioGio (a "Jo" sound rather than a "Gio" sound).

Non-protagonists who may be considered "JoJo"'s:
 *  Geo rge  Jo estar I
 *  Geo rge  Jo estar II
 * Norisuke Higashikata IV (born Josuke)
