It's the season for student teachers at Mai High.  Keima's class gets Miss Nagase, a cheerful pro wrestling fan who has great hopes and dreams about becoming a teacher.
However, her attention is immediately drawn to a problem child who plays games during class (...Keima, of course).
The other teachers have already given up on Keima's attitude, but Jun is inspired to save him...
I'm so glad to be in this class!
¡Qué gusto me da estar en esta clase!
¡Qué feliz soy de estar en esta clase!
Que bom que estou nesta sala!
