الحلقة 4: يهزم جو بلا ترس شام شيماجيما ويتصدر المرتبة 102 قبل مواجهة خصم غامض من ماضيه.

Joe enters the ring for his first professional match against Shark Samejima, but shocks the whole arena by not wearing any gear for the fight, being dubbed "Gearless" Joe, this is all part of Nanbu's plan to have him attract attention. Joe gets knocked down in the first round which badly disorients him, but he gets up at the 9th count just as the round ends. Shark loses his temper in the second round and fouls Joe, who spends the rest of the round dodging him. During the interval Sachio chastises both Joe and Nanbu, which allows the two to focus and get their priorities straight. Joe uses his footwork to KO Shark in the third round. Some time passes, during which Joe wins 2 more fights and climbs to rank 102 while gaining a reputation for himself, even grabbing Yukiko's attention. Nanbu visits an old acquaintance to meet Joe's next opponent who is rank 17, but is shocked to find that the challenger is someone from his past with a half-burned face. (Source: Wikipedia)
