S2·E1 Jiro Meets Ichiro

Jiro is running with Reiko and Akida from a bunch of machines (sent to capture Akida). When suddenly, a mysterious Kikaider shows up and defeats them. The Kikaider takes the trio to a temple and the reverend there tells Jiro that the Kikaider is known as 01 and Ichiro. Ichiro is the older brother of Jiro but unlike Jiro, he is simple and has no conscience circuit. Ichiro then agrees to go with Jiro so that he can help.
