An android created by Dr. Komyoji to stop DARK. He acts to protect Dr. Komyoji's children Mitsuko and Masaru. Since his conscience circuit is incomplete, Professor Gill's hypnotic flute causes him pain, and is ultimately able to control him. He defends himself by overpowering its influence (for example, using a louder sound to drown it out). Jiro has a guitar, which he uses to announce his presence and motorcycle, which is called Sidemachine. He often defeats Destructoids by using his special attack called Denji Endo (Electro End). Jiro is played by Daisuke Ban in his human form while Toshiaki Kikuchi plays his robot form.
