Daisuke_Jigen

Daisuke Jigen (Japanese: 次元 大介, Hepburn: Jigen Daisuke) is a fictional character created by Monkey Punch for his manga series Lupin III, which debuted in Weekly Manga Action on August 10, 1967. Jigen is the marksman, aide-de-camp and best friend of Arsène Lupin III. Along with colleague Goemon Ishikawa XIII, he joins Lupin in pursuit of riches acquired typically by theft. Traveling across the globe, Jigen has garnered fame as a gunman with a wildly capable speed and accuracy.

His name comes from Monkey Punch's love for the word "dimension," which translates to "jigen" in Japanese. In an interview with Mainichi Shimbun, he stated the name is a corruption of the Japanese phrase "jigen daisuki" (次元大好き, "Iove dimensions").
