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!
He's probably ransacking Hina's desk right 
about now and has her recorder...
Seguro que ha curioseando en el pupitre 
de Hina-chan y ha tomado su flauta...
Ele provavelmente está pilhando a mesa da
Hina-chan agora, e com sua flauta doce...
