Nikawa Kazumi (仁川一実) is beloved amongst all the students in a certain prestigious all-girls Catholic high school... She assumes the highest position, representing the school's ideals and romanticism, and all of her classmates admire her. However, she struggles to conquer Sekiguchi Juuko (堰口十子), a corrupt delinquent who resides in her own self-proclaimed occult club. Despite their disagreements, Nikawa cannot control her feelings for Sekiguchi.
Even if Nikawa could play with the rest of her dolls whenever she wanted...just the fact that there remained one she could never control bothered her to no end. No amount of demons could compare...to the influence she started to have on Nikawa. Though, not even she understood what exactly that was...and she would put off those feelings, fearing them...until the day eventually came when there was no one else but them two. The school became empty. Somehow, inexplicably, at a point no one remembered. Perhaps everyone graduated. And Nikawa was left alone, still unable to grow up... And if it were that Sekiguchi who put that spell on her, then...
She could only prepare herself be kneeling at the confessional. Where those eyes that always listened to her...that were always with her...would gaze upon her.
