Anise is granted four cards representing four gorgeous knights whom she can summon with a kiss.
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?!
Fearing her absent father will return and discover her rose choker missing, Anise commands her knights to do a search for the necklace. Before they can set out, new transfer student Haruto Kisugi appears. Anise and he were friends back when she was living in Osaka, but her four knights—especially Kaede—do not trust him.
