Kyoka was raised strictly in a wealthy household, and from an early age she sensed that she was different from others. This awareness gradually evolved into a masochistic tendency, which she carried as a secret while growing up. Her boyfriend was sexually normal, but one day, while drunk, he had rough sex with her—this incident became the turning point where she realized her true masochistic nature. Overcome with guilt over this revelation, she grew distant from him and their relationship eventually faded. Today, she has found fulfillment by building a master-servant relationship with a dominant partner she met through the personal ads of an SM magazine.
