Medaka Box - S02

After Myouri Unzen is defeated by Medaka Kurokami and her Student Council, peace returns to Hakoniwa Academy, though only for a short while. Soon, Medaka, Zenkichi Hitoyoshi, Kouki Akune, and Mogana Kikaijima are pulled into another sinister scheme known as the "Flask Plan," led by the school's principal himself. But the council's first problem is a whole new group of superhuman students calling themselves the "Thirteen Party," led by the egotistical yet powerful Oudo Miyakonojou. With the mysterious Flask Plan, Oudo's tyranny, and the return of an old enemy, Hakoniwa Academy is far from calm, and Medaka and her friends have their hands full as things only get much more abnormal.
