Move history. Move hearts. Move destiny. Move the stars. The story takes place in 15th-century Europe, a time when heretical ideas were met with severe punishment. Rafal, a gifted young scholar, is set to enter university ahead of schedule to study theology. As someone who values reason above all else, he sees this as a natural choice. As long as he follows reason, the world should be simple. But one day, a mysterious man appears before him. The subject of his research is a certain truth—one considered heretical by the authorities. Is there a belief you would never abandon, even at the cost of your life? Is there an ideal you would uphold, even if it meant standing against the world? From Uoto, creator of Hyakuemu, comes a story about people driven by convictions powerful enough to change history.
