Manservant

Manservants of Nazarick are a group of ten butlers that maintain the upkeep of the 9th and 10th Floors of the Great Tomb of Nazarick.

Background
The Manservants, like the Homunculus Maids, are responsible for the various minor miscellaneous jobs, especially the cleaning on the 9th and 10th Floors of Nazarick. They are subordinates to Eclair Ecleir Eicler.

The Dark Warrior Arc
One Manservant was attentive at his Eclair's side, when he was speaking to Demiurge. The butler monster then carried his superior to his next destination.

The Lizard Man Heroes Arc
Eclair had a Manservant carry him to the bar in the 10th Floor. Sous-chef served the penguin a drink, and while he offered one to the butler, he was declined.

The Two Leaders Arc
One Manservant was manning a buffet table in the staff canteen, serving food to the Homunculus Maids. Another of its colleagues, had come into the canteen following CZ2128 Delta as she carried the assistant butler in her arms.

Strength
They are domestic workers and far have displayed no combat abilities. They also seem to possess some cooking skills as one was able to make an omelette.
