Satsuki Hikawa's high school student lives alone in the mansion, while his grandfather, who is the only living family member and Art dealer, travels around the country. One day, Grandfather Satsuki sends him a feature book called Tablet. It seems that each page of the book presents different Tarot cards, but most of the characters are missing. Shortly after receiving the book, the mysterious girl breaks into the house of Satsuki and claims that she owns the tablet, and Satsuki says that all missing characters should be found and returned to the book before "they" make any leisure. To find and return symbols, Satsuki should call the correct characters to defeat the fugitives. Any character you will return to the book will become your servants. Can Satsuki find and capture all the characters that escaped?
