Description
Ruka Sarashina is a high school student and rental girlfriend affiliated with a different agency than the primary female lead. Born with congenital bradycardia, her resting heart rate rarely surpasses 90 beats per minute, restricting strenuous activities and causing lifelong social isolation. Seeking heart-racing experiences and genuine affection, she entered the rental girlfriend profession.
Initial clients failed to elevate her pulse until a chance encounter with Kazuya Kinoshita, who accompanied another rental partner. During this meeting, her heart rate surged unprecedentedly—an occurrence she deemed proof of authentic emotional connection. Witnessing Kazuya’s sincerity toward rental girlfriends solidified her intense feelings, prompting her to confess her love and resign from rental work.
To secure Kazuya, Ruka exploited her knowledge of Chizuru Ichinose’s rental identity and Kazuya’s fabricated relationship with her. She blackmailed him into a "trial relationship" in exchange for secrecy, establishing herself as a constant fixture in his life and fueling tension with Chizuru. Later, she joined Kazuya’s workplace, a karaoke bar, for closer proximity.
Cheerful, passionate, and direct about her emotions, Ruka’s medical history fostered possessive and self-centered tendencies. These manifest as stubbornness, impulsivity, and tantrums when thwarted. She aggressively infiltrates Kazuya’s family events and social circles, vying to replace Chizuru in their regard. Despite her pushiness, she displays restraint in critical moments and yearns for Kazuya’s validation and familial acceptance.
Her appearance blends youthful charm with a womanly physique, highlighted by a prominent bust and slender legs. At 153 cm (5'0"), she is the series’ shortest female character. Distinguishing traits include short black hair, blue eyes, and a signature ribbon—typically blue—in her hair. She predominantly wears her school uniform: white button-up, tie, blue blazer, and short skirt. Rental dates feature turtleneck sweaters and patterned short skirts, while casual outfits include sundresses or modest long-sleeved attire with leggings. Blue is her favored color.
Throughout the narrative, Ruka relentlessly pursues Kazuya despite his preference for Chizuru. Her tactics include generating popular social media content, amplified by her physical appeal. Her story arc centers on cementing the trial relationship while contending with Kazuya’s emotional distance and complications from his bond with Chizuru.
