* Based on a light novel series written by Iwata Hiroki and illustrated by Satou Toshiyuki.
Everyone calls it "Beatrice". That strange power that responds to the will of certain people and is capable of doing many wondrous and dangerous things. And Yoshimura Mamoru has been accepted to a high school that specializes in teaching the use of the strange "magic power". On his way to school, he sees a pretty 2nd year student standing under the cherry trees. After a few words with her, she suddenly blushes and asks him to go out with her! In his first class, he is surprised to notice that everybody is staring at him - because of the rumor that Takasu Ayako, the "angel of death" actually confessed to him! And then suddenly, he is summoned to the student council chambers and is offered a position with Takasu-sempai's on her student committee! It is going to be a very busy school year for Mamoru.
Mamoru's new girlfriend is Takasu Ayako. She is a year older than him, a lot taller, very beautiful, the committee leader for school discipline, a genius at using her "Beatrice" powers and the TERROR of the school. Nobody would ever believe Mamoru if he tried to tell them that she is really a very nice and shy girl.
