The Irregular at Magic High School

Siblings Tatsuya (a slacker known as a Weed) and Miyuki (a bright Bloom) enrol at the Magic High School.

The president of the student council asks Miyuki to join the student council; Miyuki considers it, but only if her brother can join.

Everyone is surprised at Tatsuya's defeat of Hattori; Miyuki has mixed feelings about her brother.

Mibu thanks Tatsuya for his help and asks him to join the kendo team; Tatsuya is suspicious of Mibu's motives.

Mibu tells Tatsuya that they are planning to let the school know their thoughts about the discrimination among the students.

There are intruders in the library, and they have Mibu; Tatsuya and the others work to fight the intruders and save Mibu.
