Description: You play as a young man who finds himself in a mysterious otherworld. What is this place? And who is the alluring demoness standing before you? Meet Yuka, a messenger of the devil, who arrives to tell you about your mission. Before your birth, you were meant to die alongside your mother during childbirth. In desperation, your father begged for your life. A devil heard his plea and offered a deal: your life would be spared, but you would one day serve hell. Your father accepted. Now the devil has come to claim his bargain, sending you to spread depravity and sex alongside loyal demonesses.
