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!
Hey, maybe Hayata's mistakenly 
wandered into the old school building.
Puede que Hayata-kun se haya metido 
por error en el edificio antiguo...
