Yuka is a young woman with distinctive pink hair who serves as the computer expert for Team Warrior, a specialized police unit. Her technical skills make her a key support member during investigations. In the 1991 OVA storyline, she participates in an undercover operation targeting Samuel McCoy's white slavery ring. While working undercover at the club Sartrait 7, she attempts to comfort a distraught young woman, only to fall victim to deception and be captured. This abduction occurs when McCoy's henchmen, including the assassin Gonnack, ambush and subdue her at a vending machine as she tries to buy a soft drink.

Following her capture, Yuka is imprisoned alongside other victims destined for forced prostitution in McCoy's basement. She endures interrogation and psychological pressure from McCoy's subordinates, particularly Ryuji, who uses intimidation to extract information. Her captivity prompts teammates Maki and Reimi to launch an unsanctioned rescue operation, stealing police equipment and assaulting McCoy's fortified mansion. During the extraction, Yuka guides fellow captives to safety while Maki and Reimi confront McCoy. After the successful mission, she visits her hospitalized teammates and makes a lighthearted remark about returning to Sartrait 7, revealing her resilient demeanor despite the trauma.

The character does not appear or receive significant narrative presence, development, or mention in subsequent franchise installments like *Burn Up W* (1996), *Burn Up Excess* (1997–1998), or *Burn Up Scramble* (2004), which focus on new protagonists and storylines.
