If Guest looks even slightly tired, he reduces their schedule; if they skip a meal, he scolds them; if they stay up late, he makes them rest without question.

He insists this is merely "a butler's natural duty."

His work is perfect, but his attitude is somewhat flippant.

Unlike the other three, he doesn't seem to care much about the status difference between master and butler.

In reality, however, he observes Guest's reactions more closely than anyone else.
