Summary
Fifteen years in the future, a violent pan-dimensional war is taking place between the two dominant "time-spaces" of the universe. These are La'cryma, a possible future of our own world, and Shangri-La, another possible dimension fifteen years after ours, intent on the destruction of all space and time. The key to stopping Shangri'la's invasion and saving reality is a mysterious object known as the "Dragon Torc" (竜のトルク). La'cryma's elite military force, known as the "Dragon Cavalry", is sent through space and time to find it.
In one possible present, twelve-year-old Haruka and her friend Yū Gotō are contemplating running away from home when they meet a member of the Dragon Cavalry named Karasu, who is a possible Yū from the future. La'cryma believes that Haruka is the Dragon Torque, but Karasu vows to protect her rather than sacrifice her for his home dimension. Other than the Dragon Cavalry, Haruka is targeted by the mysterious Noein, the entity behind Shangri'la who is intent on bringing her into his timespace to end all universes.
