One star, two worlds. How can I save the shattered space-time? [Synopsis] In the world of "Sapphire Sphere", human beings have a highly developed scientific civilization, but they are paying a big price for excessive consumption of life energy called spiritual elements. I was trying to pick you up. Mankind devised a plan to save the dying planet, repeated many trials and errors, and finally created a dimensional gate called "Blue Boundary" in the "Ninth Star Saving Plan". Because the flow of time slows down inside the gate, humans migrated there to wait for the revival of their home planet. However, in the first plan that was abandoned in the past, a sister who was remodeled in the plan was left behind in the ruins of a dying planet. With the desire to "be loved", they created a new intellectual life form and built a new paradise "Erin". Finally, the dimensional gate and blue boundary are destroyed, and a war breaks out between the two worlds. The story of promise and rebellion (Uragiri) began here...
