The anime centers on a girl named Elaina. When she was a kid, she loved reading books. And among all the books she read, there was a series called 'Niike's Adventure', which was her favorite. It was a collection of short stories about the witch Niike's adventures around the whole world, based off of the writer's own life experience. Elaina liked Niike's adventures so much that starting her own adventure became her all life's dream.
