MKON-111 - My beloved girlfriend was brainwashed by the leader of a cult and degraded until she became an anal rape toilet for believers, Shiina Kokoro.

I went to the house of my first girlfriend, 'Kokoro-chan'. A large photograph of the leader of a cult was displayed in the living room, and I was told that all of Kokoro-chan's family members except for her were fervent believers. Of course, that didn't change my love for Kokoro-chan. Just as we were getting into a good mood, Kokoro-chan's older brother came home. 'We are about to perform an important Ring Ceremony, so I'm sorry, but you'll have to leave today.' I don't intend to interfere with the family's faith, so I'll go home today. I never imagined that such a thing would happen after that...
