When Ichika wakes up, she finds herself in a pitch black room... and is chained to a collar. In front of me is a creepy man who doesn't say a word...I don't know why or how I got here, and now I've started living a life where I'm being harassed 24/7! When the limit of sexual intercourse is exceeded by being silently forced without a break for 24 hours, what are the feelings left behind? Take a closer look at the well-developed story and Ichika's soulful play, which sets it apart from ordinary rape works!
