The protagonist is Tarot Card No. 0, "The Fool", and is a fantasy adventure story that takes place on the fictional continent of Reforst. He originally wanted to take his loyal dog Sancho on a long-planned trip, but he encountered a huge threat that was not part of his plan but was destined. Other Tarot cards encountered along the way, after learning about the unspeakable existence that may threaten the safety of the entire continent, helped "The Fool" to varying degrees, and "The Fool" finally assumed the meaning of "the world".
