This is a hardcore fan question, but in Masaya Tokuhiro's Watery Friend: Kappaman Volume 1, Page 93, Panel 4, why is "Eiichiro Oda" written there? Were you working on it as an assistant or something?
Whoa, scary! You noticed. Yes, I was an assistant.
My history as an assistant manga artist includes work on Shinobu Kaitani-sensei's Midoriyama Police Gang, Masaya Tokuhiro-sensei's Jungle King Tar-chan and Kappaman, and Nobuhiro Watsuki-sensei's Rurouni Kenshin.
I learned many things from those three. Seriously, I respect them all as manga artists and as people.
