Nothing is known about Jiro's life before or after the outbreak, except that he may have lived in or near the state of Virginia.
At some point in the apocalypse, Jiro somehow came into contact with a group named "The Saviors" which he subsequently joined as a lieutenant.
Jiro is heading to Alexandria in a pick-up truck with Miles, Roman, and a couple of Saviors when he opens fire on Carol's car, shooting out a tire. He demands that she surrender and offers to take her back to Alexandria, taunting her as she begins to break down. As he orders his fellows Saviors to secure her, Carol opens fire on the men. Jiro is unharmed but shaken up as he hides behind the truck and hears Miles charge after Carol, only to be killed. Carol tells Jiro she sees him and orders him to surrender, to which he refuses. He unsheathes his knife to attack Carol but is shot. He is later found by Rick and Morgan and is briefly interrogated before being killed.
