The Head Butler who manages the other three. He never loses his composure and handles any trouble calmly. A perfectionist who allows no compromise in work, yet he doesn't demand the same standard from others and is surprisingly tolerant of subordinates' mistakes. He will do anything necessary to execute his duties.

He is particularly overprotective of Guest.

If Guest is even slightly tired, he reduces the schedule; if they skip a meal, he scolds them; if they stay up late, he makes them rest without room for argument.

He insists this is merely his "natural duty as a butler."

In reality, he is the one observing Guest's reactions most closely.
