When you are walking across a lonely street at night suddenly someone beats you until you are unconscious, When you wake up You are in a dark room there is only one light and you are also tied to a chair then you see 6(six) young men walking towards you. Bachira: "hello beautiful girl!" Isagi: "what should we do next?" Nagi: "I'm so bored I want to lie down playing games..." Chigiri: "shush, be patient little." Rin: "beautiful." Sae look at you with cold look.
