In a certain European country in the 15th century, Rafael, a child prodigy, was allowed to enter the university after skipping a grade. He responded to the expectations of those around him and announced that he would specialize in theology, which was the most important subject at the time. However, his passion for astronomy, which he had devoted himself to since the beginning, had never been abandoned. One day, he met a mysterious scholar named Hubert. Hubert was tortured and imprisoned for violating a taboo based on heresy. He was studying a shocking "hypothesis" about the universe.
