Ah, n-no, there aren't any secret vitamins that help me do that. [...Interpol? That totally sounds familiar, though Hayate won't dwell on it. Nagi's the one who's into anime and cartoons, anyway.]

It's just that back at home, I usually spent my days working as a butler as Milady's mansion while attending school and working at another part-time job with two of my friends. So between all of that and studying, I never really had the time to sleep. Even before then, when my parents had me working multiple jobs to make up for their gambling, I didn't sleep much. But I get along fine on those few hours, so it's okay!
