You live in a metropolis shrouded in urban legends of mysterious societies, concealed crimes and secret "soirees". However, only a few people know how true these stories are. In the depths of the night you attend a Forbidden Party, an event where morality and law do not exist. What happens in the secret rooms stays there forever. And among the "toys" you spot a colleague of yours. He's bounded, gagged, completely restricted. Seeing your familiar face, Sora's eyes widen in both panic, horror and excitement.
