In 1976, while still a student at the Kyoto University of Art's department for traditionalist nihonga painting, Itahashi debuted with "Pale Cocoon" (Monthly OUT, Minori Publ.). In 1981, his "Run away to Lucky Route" (Weekly Shonen Jump, Shueisha) was accepted for the 21st Tezuka Award. In 1986, his series "AI CITY" (Super Action, Futabasha, 1983-1984) was adapted into an animated movie. Itahashi's specialty is SF action manga, and one can trace the influence of foreign, especially American, comics in his rendering of characters and onomatopoeia. At present, he publishes mainly webcomics under the pen-name of SYUFO. Apart from manga he created the scenario for the TV Game "Running High" (1997), as well as the Play Station comic "Carol the Dark Angel" (1998). He also works as a designer of monsters for SFX television productions.
