The eldest lady and her seven younger brothers live a busy life in the magic academy.
Teacher: What do you want to do most after learning magic?
Dream: Beat my seven younger brothers
Second brother: Beat up my six younger brothers
Third brother: Beat up my five younger brothers, and the remaining younger brothers will pass it on in turn, until they reach the last younger brother.
The youngest ("Are you okay?" Face): Then I hope none of them can learn it (gnashing teeth).
