Yuri Sakazaki is a friendly young girl who always cares about her family and friends. She is a strong believer of innovation and trends, constantly finding ways to improve herself through change. She is often arguing with her father and Ryo over matters regarding her newfound sense of independence.
In the Art of Fighting series, it is heavily implied that she has a romantic interest in Robert after her kidnapping. As of Art of Fighting 3, she is confirmed to be in a relationship with Robert. Though still present to a certain degree, this attraction and relationship is downplayed in the King of Fighters series, and is sometimes the humorous cause as to why Robert is suddenly being beaten up by Ryo and Takuma.
Yuri, now confident in her fighting prowess, decides to enter the tournament, but is denied to enter by her brother. She defies his wishes and enters with King and Mai. It isn’t until the 1996 tournament that they finally form a team together to represent the prestige of Kyokugenryu to the world. She is forced to join when Takuma gives her an ultimatum to either enter with Ryo or leave the house.
After the 1999 King of Fighters tournament, Yuri wanted to once again show her independence. She begs King to take her place for the year and joins the Women’s Team. In 2001, Robert reveals to the family that his family business is in trouble. They decide to all enter together to win the prize money and help out Robert’s situation. Since 2001, Yuri then has been a regular for the Art of Fighting team alongside Ryo and Robert. In The King of Fighters XI, Yuri has a rival in the form of Malin. She stuns her father with her whimsical haircut before KOF XIII and is upset by her family’s eccentric reactions. Since the rising skill of martial artists in the tournaments outclasses her basic training, Robert informs her of her brother and father’s wishes to quit Karate for her own safety. Optimistic in her attempts to improve herself, however, she teams with Mai and King for the newest tournament.
