Once upon a time, there was a witch named Ireina. Her journey with her master is approaching its end. During this time, she encounters a mermaid troubled by love and a shy traveler. The young "Witch of Stardust" and her troubled master, along with a cantankerous novelist. Sisters searching for a new hometown and a wizard living in a ruined castle in the sky. A devil lurking in a book, a broomstick, and a magical doll shaped like the "Witch of Ashes." And the "Witch of Coal," who is heartbroken after losing her dear friend... Various events hold the two back, as if to prevent the end of their journey. "I have always been here since we first met, haven't I?" Guided by the countless lights dancing in the night sky, the girls create a miracle that lasts for just one night.
