[Some sins, once committed, will follow you throughout your life until death. ]
If time could go back to that day ten years ago, Takagi Yoichi would definitely choose...
Yoichi accompanies his girlfriend and a group of people to try their luck at the "ruin of ghosts" that is popular on urban supernatural forums. This so-called "ruin of ghosts" is actually the high school dormitory where Yoichi lived ten years ago. A fire turned the dormitory into a hell on earth, which is the darkest memory that Yoichi hides in his heart.
Now that he returns to his old place, what will be waiting for him...?
