GGEN-015 I was trapped in a room where I couldn’t get out unless I had intimate relations with someone other than my boyfriend… Mitsuki Nagisa

The best kind of challenge is one that benefits no one, lol. Come on, shake off your despair, you fools, lol. As usual, after stopping by the convenience store on the way home from school for just a moment… I have no memory of what happened. Where am I? Hey, why are you here? A locked-room mystery that raises even more questions. The only way out is… well, you can’t leave unless you find a way to escape together.
