As a part of class studies home teacher chose 9th Amendment to the constitution as a debate topic. The classroom is going to become the battlefield between supporters of 9th Amendment and revisionists. Naoki did not have particular interest for the agenda and kept neutral position. "Please stand up with the Guardians !!" "Please enter the constitutional reform faction !!" Bribe? Intimidation? Venus trap? All means are good to bring Naoki to one's camp. Shall Naoki give in to pressure or be able to find his own answer on the matter?
