Ryo Sakazaki is the main protagonist of the Art of Fighting series.

Personality
Ryo is very serious about fighting and loyal to his friends and family. He has been given discipline through his Karate training by his father, Takuma. He treats Robert as his rival, but they are best friends. He is a little old fashioned and blunt, which sometimes alienates him from his trendier sister and stylish rival. He's also admits to not being very smart or talented but he believes that these are obstacles for him to overcome. Compared to Yuri and Robert's ideology on training, Ryo believes he can attain greatness in his art through hard work and experience. Having raised both himself and Yuri during their childhood, he struggles with his own wishes to protect his sister and his own wishes to see her grow up. He accepts her growing maturity with bittersweet acquiescence.
