Hayate wants Nagi to attend school on a daily basis. One day, however, when returning from school, Nagi forgets a notebook, and as her butler, Hayate goes to the academy to get the notebook. However he arrives at night.... in an area that's supposed to be haunted!
This is what happens when 
I make a rare excursion to school!
¡Esto es lo que pasa cuando hago 
una excepcional visita a clase!
É isso o que acontece quando eu 
finalmente resolvo ir para a escola!
