Hiroshi features solely in Shōjirō Nishimi's one-minute Studio 4°C short "Invasion from Space - Hiroshi's Case" as a young boy engrossed in reading a manga within his room. A small robot abruptly disrupts him by firing pellets, deliberately interfering with Hiroshi's reading to create a distraction. This tactic enables the robot's swift escape from the room. Hiroshi's entire documented narrative presence revolves exclusively around this fleeting encounter.
