Here’s an overview of the game’s story:
Those who possess the “mark” will die. In the Tokyo metropolitan area’s H City, where such rumors began to circulate, a case thought to be a suspicious death as a result of the “mark” had occurred. This “mark” was unexpectedly engraved onto the body, literally like a birthmark. The cause of the birthmark is uncertain and has invited various rumors, such as it being the result of a ghost encounter somewhere or unknowingly coming into contact with a curse. One day, among those who possess the “mark,” people were invited to a certain mansion. You are among those people. “Welcome to Kujou Mansion.” The lord who greets you is a beautiful doll who speaks language. The doll quietly began to speak, “You will die if you stay like this…” “but that doesn’t mean that there isn’t a way to be saved.”
Death Mark is due out for PS Vita in Japan in summer 2017 for 4,800 yen.
