Takeshi Kawai

Ring ni Kakero (リングにかけろ, Ringu ni Kakero?), or Put It All in the Ring, is a manga created by Masami Kurumada. A total of 25 volumes were published in Weekly Shōnen Jump between 1977 and 1981.

The story centers around the life of a young boxer named Ryuuji Takane and his sister Kiku, who is also his coach. Their father had been a famous boxer but is now deceased. Ryuuji and his sister both inherited their father's talent for boxing: Ryuuji inherited his strength and techniques, while Kiku picked up his talent for analysis and strategy. Ryuuji and Kiku leave home to train and become famous in order to help their lonely mother. On the way to stardom, they have to defeat the strongest challengers all over the world.

In Ring ni Kakero 1, the characters are briefly introduced, telling the story from the moment Ryuuji and Jun Kenzaki, his eternal challenger and supposed best friend, achieve stardom and fight for the National Boxing Title. Ryuuji's sister then tells the story from the beginning, when Ryuuji was the finalist in a local youth championship and had to compete against Kenzaki, the latter winning in a close K.O. one-to-one fight.

Afterward, most of the series depicts Ryuuji as being Kenzaki's successor after Kenaki was terribly injured and almost crippled. Ryuuji competes in the Japan National Boxing Championship, where he encounters strong and deadly opponents, including:

Ryuji also fights opponents from the United States (Black Shaft) and France (Napoleón Baroa). He fights an opponent named Führer Skorpion, who orders a fellow member of the Boxing Team to spy on Kenzaki and Ryuuji as possible threats to the World Championship.
