Snow? In the classroom? Mumei and Koui face a new test and attempt not to freeze to death. A mysterious examiner awakens from his 10,000 year slumber to whip these cheating students into shape. However, things take an unexpected turn when Mumei's crush, Ryuu Haku, is accused of cheating. Will Mumei be able to clear her name and win her favor?
I repeat, Ryuu Haku, the Class 1-1 
student who took the test earlier—
 1-1 أكرّر، على ريو هاكو، طالبة الصف
التي أخذت الامتحان للتوّ القدوم
Wiederhole:
Repito, Ryuu Haku, de primero,
la estudiante que tomó el examen…
Repito, Ryuu Haku, de primero.
La estudiante que ha hecho el examen.
Ripeto.
Repito, Ryuu Haku, que acaba de fazer 
um dos testes, venha imediatamente...
