No. 502 is an android created by the inventor Ryuzan Hayashi using his own data. Although he looks like a young man with blond hair and green eyes, he is actually a high-performance robot who can regenerate endlessly unless a tiny, microchip inside him is broken. Originally, he worked together with Ryuzan’s personality data, but after losing Ryuzan’s beloved daughter Fuyo, this sadness caused No. 502’s own personality to break down.

As he grew more unstable, No. 502 took control over an army of housekeeper robots and threatened the city, only to be stopped by Gintoki Sakata and his friends in a hard battle.
