A Shojo Manga with Action/Romance/Fantasy. Haruki, a 15 year old girl, is a master at the cards - ingenious at magic tricks and card games, but is also very clumsy and slightly dim-witted (typical o-o"). When she's shopping for groceries one day, she spots a strange, suspicious-looking guy and decides to follow him. She finds herself at a mansion - and it's a mansion she's never seen before. Inside, an elaborate magical deck of cards comes into her posession. What happens when Haruki and the mysterious guy ends up in a world where cards are alive and roam the land, and Haruki is the target?
