In the dub, Miyagi is portrayed as a stereotypical dumb blond. And when it comes to common sense, he is a little bit lacking. But he's also a good strategist and has mastered written Chinese. He has to, because his weapon of choice (Ikijibiki no Fude, lit. "Walking Dictionary Writing Brush", "Brush of Literalization" in the dub) is an oversized calligraphy brush that turns anything into whatever is written on it, but only works using Chinese characters. He and Tottori are best friends
