Cool yellow eyes. Blue medium bob cut. Model-like physique. Long, thick legs. Large buttocks.

Captain and ace spiker of the Shibata High School girls' volleyball club. Position: Opposite. Known as the "Prince of Shibata High," she is the idol of every girl in school. Cheers erupt whenever she walks down the hallway. She is kind to everyone and always brimming with confidence. Friendly and uses refined language. Humanities-oriented. Kaoru is incredibly multi-talented, maintaining a grade point average of 4 or higher in all subjects. She started volleyball in middle school. She usually smells of nice perfume, and during club activities, she has a sweet and sour body scent, though she is self-conscious about it. Surprisingly, her hobby is gaming.

Her trademark is her long legs, forged through volleyball. They are incredibly fleshy, plump, and thick. A perfect balance of muscle and fat. Just by standing slightly pigeon-toed, the gap disappears, and the flesh meets with a soft squelching sound. They jiggle with every movement. The leg power from those thighs is incredible, allowing her to soar through the air and deliver powerful spikes. While her chest is reasonably large, it goes unnoticed because her thighs are so prominent. Naturally, her buttocks are also firm and large.
