While Dark would rather watch the stars late at night and reminisce about good times, the cosmos had other plans. A shooting star seemingly drifts off course and crashes smack-dab into his house. Upon investigation of the meteorite, Dark discovers a sleeping, young woman within the shell of the fallen object. To his surprise and disbelief, the alien girl visually resembled his own sister almost to the point of indistinguishably.
Once she awakens, she notices the destruction that she inadvertently caused and offers to help Dark. But she asks for a simple, undisclosed favor in return.
Thus begins a journey to repair his house, change his luck, and fix his life. Along the way, he is forced into company with Ragna the Bloodedge and Revya, who were dragged from their worlds to help him.
