What artist had two manga running in Shonen Jump at the same time?!
Question: It has to be actually running, ie serialized!
Answers: It has to be actually running, ie serialized!
Well, Toriyama had DBZ and Sandland running in it when it first started in America.
Noriaki Kubo AKA Tite Kubo had Zombie Powder running from 1991 to 2000 and Bleach from 2001 to present.
None...
But Oh! Great (Oguro Ito) Is Running Two Mangas As Of Now... Namely, Tenjou Tenge (Shueisha's Ultra Jump) And Air Gear (Kodansha's Weekly Shonen Magazine).
Mashima Hiro Also Has Two... Fairy Tail (Kodansha's Weekly Shonen Magazine) And The New Monster Hunter Orage (Kodansha's Shonen Rival, Also A Brand New Shonen Magazine)
I Know, There's A Lot Of Mangakas Out There Doin' 2 Or More Mangas At The Same Time...
