Ring ni Kakero 1: Nichibei Kessen-hen

Ryuuji Takane's victory in the Champion Carnival is quickly followed by a challenge from Black Shaft, the U.S. Junior Champion, who seeks to test Japan's top boxers before the World Tournament. Ryuuji, along with Takeshi Kawai, Kazuki Shinatora, Ishimatsu Katori, and Superstar Jun Kenzaki, must demonstrate their world-class abilities in preparation for the event. Black Shaft is not only assembling a team of boxers but also recruiting a Death Row inmate and the leader of the Great Angels, a notorious American gang. His team also includes a mysterious woman and the "Dark Emperor of the South." Additionally, Shaft reaches out to Don Giuliano, the Italian Junior Champion, as a precaution.
