Kise Yukawa is a fictional character from the anime and game Girl Friend BETA. She is a sixteen-year-old second-year student at Seiou Academy, belonging to class 2-A. Kise holds the position of vice president of the Chemistry Club, a role that perfectly aligns with her primary passion for scientific research. She is often seen wearing a white lab coat over her school uniform, as she spends most of her time indoors, deeply immersed in her studies and experiments.

In terms of personality, Kise is a quintessential science enthusiast with a strong inclination toward research. Her hobbies include coming up with formulations, testing them, and building or creating things. This dedication, however, sometimes takes on a mad scientist quality, as her experiments frequently result in failures such as explosions, billowing smoke, or melting equipment. Despite these mishaps, she remains undeterred, often using herself as a test subject for her creations. Her speech patterns are notably old-fashioned, as she uses the first-person pronoun "wagahai" and refers to others with the honorific "dono."

Kise has a distinctive appearance with light green, straight hair that falls to her chest and blue eyes, though her eyes are usually hidden behind a pair of swirly-lensed glasses. When she removes her glasses, she reveals a conventionally cute face; however, she has no personal interest in her own appearance. Standing at 148 centimeters tall, she has a small stature. Her birthday is January 23, making her an Aquarius, and her blood type is AB. She has a particular fondness for curry and dislikes green peppers, with chemistry being her best subject.
