Trama
After a humiliating defeat against Tiger Ozaki, Joe agrees to another bout despite Danpei's protests. Under Tiger Ozaki's guidance, Ryu Harajima, Joe's opponent takes advantage of Joe's weakness in the ring. To prove them wrong, Joe unleashes a punch to Harajima's temple, the same punch that killed Toru Rikiishi. However, an unexpected physical reaction suddenly overwhelms Joe.
