Usuto Yoshii (よしいうすと), Marty Flang in the Vitello and Phuuz dubs, is a 44 year old manga artist and Masao's favorite idol. He lives in the same neighborhood as Shin-chan. He often gets ideas from Shin-chan. He is a parody of Yoshito Usui himself (the creator of Crayon Shin-chan), and his name is an anagram of the author's own name. He is the author of Fubukimaru.
