One mystical object from one different dimension in one blank room, telling one past about one person's alternate life. Nobility and honor? Or agony and despair? For every person, the story and the quest within oneself differs. Depending on the item, the end goal within each person will determine the outcome of life or painful death.

19 year-old college student Suzume Akihiro is a kind, caring and overall friendly girl who puts others in front of herself. Everything seems to be heading in the right direction with her life, but one unfortunate day on the way back from college, an incoming speeding car crashes into her and her boyfriend, 20 year-old Sanjiro Nakada, leaving behind two lifeless corpses.

It's her turn in this so called "Purgatory Room", and the item that rests on a marble pedestal tells a story much contrasting to her personality. She realizes the painful trek throughout an incredible dimension that she must journey across, hoping that one day she can rest peacefully.
