Yuri Sakazaki/Story

=Art of Fighting series=

Past
As a child, Takuma dedicated more time training Ryo to be next family heir rather than raising Yuri. When she was six years old, her mother died in a tragic car accident. Sensing his family was being targeted, their father leaves in order to protect them. With the loss of both parents, she becomes fearful and heavily dependent on Ryo for the rest of their childhood. When she first meets Robert, she does not trust him but eventually warms up to him.

Art of Fighting
When she was 17, Yuri was kidnapped by Mr. Big on behalf of Geese Howard as part of a ploy to blackmail her father when he began to show signs of reluctance and resistance to continue doing their dirty work. Ryo and Robert search Southtown to find her whereabouts and rescue her. While held hostage, she finds out the identity of Mr. Karate. When Ryo defeats her captors, she reveals it to her brother and the family is reunited.

Art of Fighting 2
In order to protect herself in the future, Takuma teaches her how to fight much to Ryo and Robert's chagrin. He trained Yuri in secret, but only taught her enough to defend herself.

Art of Fighting 3
She becomes worried about Robert when he doesn't appear for their date before Art of Fighting 3. Setting out with her brother, they search for him in Glasshill. During their trip, she is wounded by Sinclair and briefly hospitalized. If the player plays through Robert's story, a strained Yuri appears to assist his plight against Wyler. She is healthy enough to leave with Robert by the end of the game's events.

Buriki One
According to Ryo, she and Robert are still single by the time Buriki One takes place. She likely stayed at home to help the family business, as she is close enough to her brother to tell him to shave off the hair from his chin.

=The King of Fighters series= Yuri's life in this timeline is exactly the same as her Art of Fighting counterpart up until Art of Fighting 2.

Orochi Saga
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.

NESTS Chronicles
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.

Tales of Ash
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.

Shun'ei Saga
By the time of The King of Fighters XIV, the Sakazaki family has opened a Kyokugen BBQ restaurant with the help of Richard Meyer.

SNK Heroines Tag Team Frenzy
Several months prior to the events of the fifteenth tournament, Kukri's obsession for women caused him to create a pocket dimension where women fighters must survive in his universe and join forces and slug it out with other women. Kukri transports most of the female fighters, including Yuri, to this pocket dimension, and they suddenly fall unconscious. Upon waking, they find themselves in a strange mansion, along some male fighters who have been changed into women. The fighters attempt to battle their way out, but are confronted by the mastermind, Kukri, who reveals he has trapped them in his castle in a pocket dimension and they must defeat him to return home.

Upon Kukri's defeat, the pocket dimension collapsed, sending everyone back through their dreams. Yuri reawakens back to reality after a nightmare where Ryo was captured instead of her in the first Art of Fighting (complete with her defeating opponents from Art of Fighting, as well as Mr. Karate being revealed to be Ryuhaku Todoh in this dream).
