Zenko Aoi (born 1962) was a Japanese man who became a fan of the Arakure Quest video game series. In 1988, Aoi was in line for the new stock of Arakure Quest 3: Quest for the Quantum Quill copies at the Don Quijote store in Kabukicho. When Kazuma Kiryu approached him to inquire about the line, Aoi told Kiryu conscientiously to get to the back of the line like everyone else.
