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!
What happened earlier is to be kept 
strictly secret, all right, Hayate?
Debes mantener en secreto lo que pasó
 recién, ¿entendido, Hayate-kun?
É para você esquecer o que você viu e 
não contar para ninguém, viu Hayate-kun?
