Anise Yamamoto has been told that if she ever removes the rose choker given to her by her father, a terrible punishment will befall her. Unfortunately she loses that choker when a bat-like being falls from the sky and hits her. Anise is granted four cards representing four knights whom she can summon with a kiss. But now that she has these gorgeous men at her beck and call, what exactly is her quest?!

High school student Anise Yamamoto is the "Rose Princess" of four handsome Rose Knights. She encountered more Rose Knights when two boys known as the Orange Rose and Lime Rose revealed themselves to be "Fake Knights" created by her father. But while searching for an Arcana Card at an amusement park, Anise comes face-to-face with another fake--and this time it's a Rose Princess!
