Manifesting itself from people's emotions, the mysterious power known as Beatrice is the most powerful magic known to mankind.
There is only one school in Japan that teaches the ways of Beatrice- Tokyo Beatrice University Senior High school, also known as TBU High.
Mamoru Yoshimura is a short teenager who looks like he's about ten years old. His smile is his saving grace, and can make anyone feel better. He is honest, cheerful, courteous and a true romantic. As a child, his life was saved by the magic of Beatrice. Waiting to learn more about conjuring and controlling the supernatural, he transfers TBU High as a freshman. He will soon discover that while he lacks development, he has a talent for controlling Beatrice and may even be a genius-level charmer. On Mamoru's first day, he saw a girl sitting under a blooming cherry blossom tree. She is a sight to behold. Before Mamoru can even ask her name, he was told by her, "We should go steady."
And that was the day that fate brought Mamoru and Ayako together.
Ayako Takasu is a sophomore at TBU High. She serves as the president of the student body and is the granddaughter of an important politician. In addition to being tall and gorgeous, she also is a genius-level Beatrice charmer capable of using her powers to do almost anything that pops into her head. The other students call her Beatrice the Witch and Beatrice the Angel of Death behind her back, but deep down inside, she is actually a very innocent girl with a kind soul.
