Mikio Itoo

Mikio Ito (いとうみきお), born in Yokohama, Kanagawa Prefecture on March 26, 1973, is a manga writer for the magazine Weekly Shonen Jump. An assistant for writer Nobuhiro Watsuki alongside One Piece writer Eiichiro Oda, his three most notable series in the magazine include Normandy Secret Club (ノルマンディーひみつ倶楽部), Granada -Ultimate Science Explorers- (グラナダ -究極科学探検隊-) and Mysterious Murasame-kun (謎の村雨くん).

Within the One Piece universe, Mikio Itoo (ミキオイトゥー) is also known as a secret gag character printed on various bounty posters through certain early areas of East Blue. Depicted as a smiling man with a gun in his hand, his bounty is known as 1,000,000 yen. Since the currency of the OP universe is the Beli, it is unknown how much this bounty is really worth in this world. Itoo also appeared as a joke character in two other series at the same time: his master Watsuki's Rurouni Kenshin and fellow assistant Hiroyuki Takei's series Butsu Zone.
