Ep. 3: Nanbu enters Joe into the rankings while they secure gear and face a prototype theft incident.
Nanbu places Joe in the Megalo Box rankings at 257th, aiming for the top bracket in five fights. They visit Goskino Factory for equipment, where a boy named Sachio and friends trade stolen cameras for Red Candy. When the drug supply proves insufficient, Sachio attacks the shopkeeper, prompting Joe to intervene. He is thrown out by Potemkin Higashi, a former Megalo Boxer. Nanbu arranges for Joe to fight the 185th ranked Shark Samejima, and training begins. Sachio interrupts, begging to go to Megalonia. After being refused, he steals a Shirato Group Composite Titanium Prototype Gear from Goskino but is caught. Joe, Nanbu, and other children rescue him. Joe attempts to fight Higashi using the Prototype, but it breaks. Surprisingly, Joe defeats Higashi without it. Consequently, Joe and Nanbu decide to take Sachio with them.
