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!
I'm sorry to ask this, but might 
I borrow the key to the classroom?
Siento pedirte esto, pero
 ¿me prestas la llave de la clase?
Me desculpe o incômodo, mas poderia me 
emprestar a chave da sala de aula dela?
