Tamatori Girl's High School teaches all their students to treat Kainarashi Boy's High School students as beings more contemptible than their parents' enemies. Get close to them as "lovers," and when their guard is lowered, that is when you kill them in their sleep.

On the other hand, students of Kainarashi Boy's High School are taught that true men are those who can placate the savage students of Tamatori Girl's High School and win their hearts. It is then that they would be hailed as heroes.
