Eiichi Yamagishi (山岸 栄一 Yamagishi Eiichi?) is the alter-ego of eponymous mangaka Eiichi Yamagishi, an assistant of Gosho Aoyama who appears in several of his series. He's known to most Detective Conan fans as the manager of Yoko Okino, who's also based on a mangaka and past senior student of Gosho and Eiichi from the Ekoda Campus of Nihon University. He also got cameos in other Gosho works, like WALK MAN, Magic Kaito, Yaiba and 3rd Base 4th, additionally to the spin-offs Zero's Tea Time and Hanzawa the Criminal, made by other people.


In Detective Conan, Eiichi Yamagishi is portrayed as a rather silent person who tries to stay in the background of things and shies away from attention, as seen by his actions, when he tried to remove evidence from an active crime scene on the hunch alone that Yoko could be guilty and was the most vocal about trying not to drag the media's attention to the whole thing, even asking not to call the police when Akiyoshi Fujie's corpse was found.
