The Honor at Magic High School

To celebrate her 15th birthday, Miyuki Shiba goes shopping with her older brother Tatsuya in Yokohama. However, they are interrupted by a call from the main branch of their family, the Yotsubas, who are members of the Ten Master Clans.

Honoka Mitsui and Shizuku Kitayama are accepted into First High. Ever since Honoka caught a glimpse of Miyuki at the entrance exams, she felt a strong admiration for her, and is overjoyed when they unexpectedly become friends.

With the club recruitment week happening at First High School, Honoka and Shizuku, who are all-round outstanding students, are asked by various clubs to join.

After observing the behavior of Mibu and the Kendo Club, Tatsuya concludes that the person who attacked him must be a member of the international anti-magic political organization, Blanche.

During the public forum with the volunteer coalition, Blanche's combat unit invades First High. Honoka and Shizuku almost get attacked, but they fight back with magic.

First High is aiming to win for the third year in a row at the National Magic High School Goodwill Tournament of Magic Skills, also known as the Nine Schools Competition.
