High school student Yuri Honjo finds herself lost in the "abnormal space". Here, countless skyscrapers are connected by suspension bridges, and "masked men" ruthlessly kill confused and fleeing victims. To get out of this purgatory alive, Yuri has only two choices: kill the masked man, or die. She decides to fight for her life to destroy this world that defies common sense. What is her final fate?
