This is the first title by Frantic LABO. Kyousuke accidentally embarrassed the new transfer student Misa. Unfortunately for him, she is fond of black magic and cursed him in revenge by locking him in the school and forcing him to search for a magic book in the underground bookcase. For some reason, she ended up cursing herself as well and also trapped his osananajimi Sayu, the timid Nono, and the rich ojousama Reika in the school. But the school grounds become a strange amusement park at night. Will they be able to find the magic book and dispel the curse?
