We are entering spring vacation where Nagi spends her days playing video games, reading manga, and watching anime until she falls asleep. Video games, manga, anime and sleep. Her routine was broken when Hayate needed to get a new cell phone. They went to a shop in Shinjuku and for the mere moment that Hayate purchases a cell phone, Nagi wanders around and gets lost. She ends up in the "Lost Children" center where a duel between two lost children is about to begin.
They took me literally when I told them
to let me sleep in over spring break,
Se lo tomaron en serio cuando les dije que 
me dejaran dormir durante las vacaciones
Me levaram a sério quando falei para
 me deixarem dormir nas férias,
