The story takes place at the end of the 21st century, when magic no longer existed only in myths and legends, but merged with science and superpowers and became a well-known existence. The country even established the First University of Magic University to train talents in this field so that they can better serve the country. Shiba Tatsuya (voiced by Yuichi Nakamura) and his sister Shiba Miyuki (voiced by Saori Hayami) are freshmen at the magic high school. Miyuki is a "crown" with excellent abilities, while Tatsuya is a "weed" who is a substitute for her. In the academy, the brother and sister met many interesting companions-Chiba Erica (voiced by Yumi Uchiyama), who is carefree and informal, Shibata Mizuki (voiced by Sato Satomi), who is quiet and timid, Saijo Leoharut (voiced by Takuma Terajima), and Yoshida Mikuko (voiced by Atsushi Tamaru), who is serious and hardworking. In the process of learning, the secrets existing in the academy are gradually revealed.
