Mahouka Koukou no Rettousei (The Irregular at Magic High School)
The story takes place in a world in which magic is not a fairy tale, but has existed for nearly one hundred years. In the spring, the Private Magic University Affiliated High School (Magic High School for short) is welcoming its new students, and names the top student with the best grades at the time of their arrival the Bloom (read as “garland” in Japanese), and the student called the Weed is the Bloom's replacement.
Twin siblings Tatsuya and Miyuki Shiba are designated as the Weed and Bloom, respectively. Miyuki is given the title of Bloom due to her amazing grades, while Tatsuya is given the title of Weed due to his poor grades. Tatsuya, the young man who always has a farsighted expression, and Miyuki, the young woman who feels far more for her brother than sibling love. Since the day the two entered the gates of the elite school, the establishment's peaceful days have become chaotic.
