The Honor Student at Magic High School, Vol. 2 - manga

It hasn't taken long for Miyuki and her brother Tatsuya to start drawing attention at First High, though for very different reasons. When the student council takes an interest, the devoted Miyuki isn't about to sit idly by while her precious brother's talents go unrecognized! But can these two siblings change people's attitudes in a system specifically designed to separate the "Blooms" from the "Weeds"?
