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'll use that time to come up with a plan.
Mientras tanto pensaré en un plan.
