Unknown Game Mashiro

Love between a death game participant and a death game organizer?! I (Kurosaki), who was forced to participate in a death game, finally lost. "If you tell me a story that entertains me, I can make use of it. It's okay ♪" suggested Mashiro, its organizer. In order to survive, I have no choice but to live up to Mashiro's expectations. I'm horrified at my memorable first love... Mashiro and Kurosaki's true intentions and the ending!
